FC17: YDelta - star-delta switchover

Function

Block FC17 is used for star-delta changeover for digital main spindle drives. The changeover can

be made in both directions (star > delta or delta > star).

Prerequisite

The prerequisite is two isolated contactors. The contactors are controlled via the peripheral

output signals configured at the FC17 outputs: "Y" or "Delta".

Internal sequence

The internal sequence when changing over between star and delta after switching over the

FC17 control signal is described in the following: "YDelta" displayed.

1. DB31,

DBX21.5 = 0 (reset feedback signal "motor selected")

DB31,

DBX21.x = 1 (set request "2nd motor data set" corresponding to the interface

parameterization DB31,

DBX130.0 - 4)

2. DB31,

DBX93.7 == 0 (feedback signal "pulses enabled" was reset) ⇒

- Start FC17 timer

- FC17: "Y" = 0 (reset output for star contactor)

3. After the FC17 timer elapses (FC17: "TimeVal") ⇒

- FC17: "Y" = 1 (set output for delta contactor)

4. After the FC17 timer elapses again (FC17: "TimeVal") ⇒

- The pulses are again internally set

- DB31,

DBX93.7 == 1 (feedback signal "pulses enabled" was set)

- DB31,

DBX21.5 = 0 (feedback signal "motor selected" was set)

Note

Drive parameters

The following drive parameters must be considered for a star-delta changeover:

• p833 (dataset changeover configuration)

- Bit 0 = 1 (contactor switchover via application)

- Bit 1 = 0 (pulse cancellation by drive)

• p826 (motor changeover motor number)

• p827 (motor changeover status word bit number)

Block descriptions

17.23 FC17: YDelta - star-delta switchover

Boundary conditions

• Block FC17 must be called absolutely and separately for each spindle.

• The drive pulses are deactivated during a star-delta changeover. The feedback signal to the

PLC is realized using:

- DB31,

DBX93.7 == 0 (pulses enabled)

- DB31,

DBX61.7 == 0 (current controller active)

– DB31,

DBX61.6 == 0 (speed controller active)

• For a spindle which is located in an axis mode such as M70 or SPOS, a start-delta changeover

is not carried out.

• For a closed-loop position controlled spindle (DB31,

DBX61.5 == 1 (position control

active) ), while the spindle is moving it is not permissible to carry out a star-delta changeover.

In the case of a fault, Alarm 25050 "Contour monitoring" is displayed, and the star-delta

changeover is not executed.

• Once the star-delta changeover has been initiated using FC17, it cannot be delayed by the

user, e.g. by waiting until the star-delta contactors change over during the course of

operation. A delay such as this must be implemented by the user in the PLC user program.

FC18: SpinCtrl - spindle control

Function

Block FC18 "SpinCtrl" can be used to control spindles and axes from the PLC. The block supports

the following functions:

• Position spindle

• Rotate spindle

• Oscillate spindle

• Traverse indexing axis

• Traverse positioning axis

Each function is activated by the positive edge of the appropriate initiation signal (start, stop).

This signal must remain at a logical "1" until the function has been acknowledged positively or

Block descriptions

17.24 FC18: SpinCtrl - spindle control

negatively by InPos="1" or Error = "1". The output parameters are deleted when the relevant

trigger signal is reset and the function has been completed.

To be able to control an axis or spindle via the PLC, it must be activated for the PLC. This can, for

example, be achieved by calling the block with activation of the "Start" or "Stop" parameter.

When you do this, the block requests control of the spindle/axis from the NC.

The NC signals the status of the spindle/axis in the associated axis-specific interface DB31, ...

DBX68.4 - 7. Once the axis/spindle is operating under PLC control, the travel command for the

active status can be evaluated via the relevant axis-specific interface.

Upon completion ("InPos" is True, "Start" changes to zero), the axis/spindle check function is

switched to a neutral status using block FC18.

Alternatively, the PLC user program can also request control for the PLC before calling FC18.

By calling this function several times in succession, a better response by the spindle/axis can be

obtained as the changeover process in the FC can be omitted.

Activation through the PLC user program is executed in the corresponding spindle interface in

byte 8.

After return of the check, the spindle can again be programmed by the NC program.

WARNING

Changed response behavior of the axis/spindle

If several block calls (FC18) have been programmed for the same axis/spindle in the PLC user

program, then the functions concerned must be interlocked by conditional calls in the user

program. The conditional call of a started block (parameter Start or Stop = TRUE) must be called

cyclically until the signal state of output parameter "Active" or "InPos" changes from 1 to 0.

PLC

Function Manual, 10/2020, 6FC5397-0HP40-0BA1

273

Block descriptions

17.24 FC18: SpinCtrl - spindle control

Note

Call note

FC18 must be called cyclically until signal "InPos" or, in the case of an error "Error", produces an

edge transition of 1 to 0. An additional "Start" or "Stop" is only possible for this spindle/axis when

the "InPos"/"Error" signal has supplied a value of 0. (the system must wait for at least one PLC

cycle with the next "Start" or "Stop"). This also applies when the assignment in data byte 8 on the

axial interface has been changed.

Abort

The function cannot be aborted by means of parameter "Start" or "Stop", but only by means of

the axial interface signals (e.g. delete distance-to-go). The axial interface also returns status

signals of the axis that may need to be evaluated (e.g. exact stop, traverse command).

Simultaneity

Several axes can be traversed simultaneously or subject to a delay by FC18 blocks. The upper

limit is only limited by the maximum number of axes of the NC.

Axis disable

For a set axis inhibit (DB31,

DBX1.4 == 1), the axis controlled via FC18 does not move. Only

a simulated actual value is generated. Same behavior as when traversing the axis for an axis

inhibit by the NC.

FC19: MCP_IFM - transfer of MCP signals to interface

Function

Block FC19 "MCP_IFM" (M version e.g. MCP 483) is used to transfer data from the machine

control panel to the NC/PLC interface:

• Modes

• Axis selections

• WCS/MCS switchover

• Traversing keys

• Spindle and feedrate override

Block descriptions

17.25 FC19: MCP_IFM - transfer of MCP signals to interface

• Program control

• Keyswitch

The following specifications apply to the feedrate override, axis travel keys and INC keys

depending on the active mode or on the coordinate system selected:

• Feedrate override

- The feedrate override is transferred to the interface of the selected channel (DB21,

… .DBB4) and to the interface of all axes (DB31, … .DBB0).

- The feedrate override signals are transferred to the NC channel in addition to the "Rapid

traverse override" (DBB5) interface byte if the "Feedrate override for rapid traverse

effective" HMI signal is set (exception: Switch setting "Zero"). "Rapid traverse override

effective" is also set with this HMI signal.

• Axis traversing keys

- When the MCS is selected, the signals are transferred to the interface of the selected

machine axis.

- When the WCS is selected, the signals are transferred to the geometry axis interface of the

parameterized channel.

- When the system is switched between MCS and WCS, the active axes are generally

deselected.

The LEDs on the machine control panel derived from the selections in the feedback.

Feedrate and spindle Start/Stop are not transferred to the interface, but output modally as a

"FeedHold" or "SpindleHold" signal. The user can link these signals to other signals leading to a

feed or spindle stop (this can be implemented, e.g. using the appropriate input signals in FC10:

AL_MSG). The associated LEDs are activated at the same time.

If the machine control panel fails, the signals it outputs are preset to zero; this also applies to

"FeedHold" and "SpindleHold" output signals.

FC19 or also FC24, FC25, FC26 can be called a multiple number of times in a single PLC cycle. In

this case, the first call in the cycle drives the LED displays. Furthermore, all actions of the

parameterized block are carried out in the first call:

• Provisioning of the mode group interface in accordance with parameter "BAGNo" (mode

group number)

• Provisioning of the channel interface in accordance with parameter "ChanNo"

• Provisioning of the axis interface of all axes up to the maximum configured axis number

• Provisioning of the spindle interface in accordance with parameter "SpindleIFNo"

In the following calls, only a reduced level of processing of the channel and mode group

interface takes place. The geometry axes are supplied with directional data only in the first block

call in the cycle.

Single block processing can be selected/deselected only in the first call in the cycle.

The second machine control panel can be processed if parameter "ModeGroupNo" has been

increased by B#16#10. When parameterizing, the mode group number is contained in the lower

nibble.

"BAGNo" = 0 or B#16#10 ⇒ mode group signals are not processed.

Block descriptions

17.25 FC19: MCP_IFM - transfer of MCP signals to interface

"ChanNo" = 0 ⇒ no processing of the channel signals.

The INC selections are transferred to the mode group interface. The activation for this

specification is done via the DB10.DBX57.0 (INC inputs in BAG area active) through this block

once after power up.

Furthermore, two machine control panels can still be handled in parallel by the FC19 block. The

first call of the block transfers the keyswitch position to the NC interface signals. Mutual locking

of the axis selections for equally assigned axes is not supported. The same applies to

provisioning the channel, mode group, and spindle interfaces.

Cartesian manual traversing

The R11 direction key on the machine control panel (at the left next to WCS/MCS) makes the

"Manual traversing in tool orientation" function available. This requires activation via the FB1

input parameter "MCP_IF_TCS" in DB7.

For "MCP_IF_TCS" = TRUE, the R11 key switches to "Manual traversing in tool orientation". In this

case, the Z key (R3) is permanently selected with FC19. The direction keys are effective for the

3rd geometry axis of the respective channel.

Flexible axis configuration

Each axis selection key can be assigned to an arbitrary machine axis. FC19 can select up to 9

machine axes using the keys of the R key group. If machine axes with a number greater than 9

are to be selected using the axis selection keys, the assignment can be dynamically changed. The

new assignment only takes effect when the axis selection is changed.

The preset machine axes 1 to 9 correspond to the axis selection keys 1 to 9 (R1 to R9 in the R key

group). The number of usable axis selection keys can be limited by the value in DB10.DBW30

(symbolic name MCP1MaxAxis or MCP2MaxAxis). If the value 0 (default setting) is used, all 9

axis selection keys that are assigned a machine axis via an axis table can be used.

The assignment or modification of axis selection keys for the machine axes is explained in the

PLC manual in Chapter "Flexible axis configuration".

Example

Machine axes 10 to 18 are to be selected on the axis selection keys R1 to R9 using a free key of

the MCP. We recommend that you proceed as follows:

• Reserve free key on MCP

• Evaluate this key as a flip-flop

• Evaluate the flip-flop output as positive and negative edge

• On a positive edge, enter axis numbers 10 to 18 (remember to enter hexadecimal values) in

the axis table DB10.DBB8 - 16 (symbolic name MCP1AxisTbl[1..9]) and activate the LED via

this key

• On a negative edge, enter the preset axis numbers 1 to 9 in the axis table DB10.DBB8 - 16

(symbolic name MCP1AxisTbl[1..9]) again and deactivate the LED via this key

Block descriptions

17.25 FC19: MCP_IFM - transfer of MCP signals to interface

Axis selection from the HMI

In addition to the 9 axis selection keys of the MCP, the active axis can also be selected in the HMI.

The axis selection from the HMI is then only taken over for the MCP if the selected channel in the

HMI matches that at FC19. With axis selection from the HMI, an initial attempt is made, as with

axis selection using the axis selection keys of the MCP, to find an assignment between the

selected axis number and the actual machine axis in the axis table of the NC-DB, refer to section

"Flexible axis configuration".

This will ensure that the same machine axis is selected with axis selection from the HMI as would

have been if the corresponding axis selection key of the MCP had been selected. If an assignment

is not possible, the axis number selected from the HMI is directly used as machine axis. As a

consequence it is possible to select axes that cannot be selected via the MCP.

Single block mode

Pressing the single block key activates the single block mode and, if the key is pressed again, the

single block mode is deactivated. If the mode is called several times for one MCP, the block

transfers single block mode state from the channel of the first call to the channels of the

subsequent calls.

Axis selections via the function "Selection of JOG axis via HMI"

FC19 supports the function "Selection of JOG axis via HMI" from software version 4.92. This

functionality can be used as an alternative to or as extended operation of the axis selection keys

of the MCP.

The prerequisite for supporting this function is explained in the PLC manual in chapter "Selecting

the JOG axis via HMI".

FC19 then only takes over a machine axis selected via HMI if the channel view of the HMI

matches the input parameter (parameter "ChanNo" of FC19). Only this can ensure that axis

selection is performed.

If a selection is made via HMI, axis selection is performed and the associated LED on the MCP axis

selection keys is activated in accordance with the axis table in DB10 (symbolic name "NC")

(alternative operation). If assignment is not possible, the axis is selected with FC19 and all LEDs

of the axis selection keys (R1 to R9) are deactivated (supplementary operation). In this case,

feedback from the selected axis is performed only via the corresponding channel DB or the view

in the HMI.

The following figure shows SINUMERIK Operate with channel 1 by way of example. The setting

of parameter "ChanNo" of FC19 for this is "ChanNo := B#16#1".

Selection of geometry axes

Geometry axes are only processed in the first block call in the cycle. Special attention must be

paid to this, in particular, when the block is called multiple times for a number of channels. For

example, if 2 channels are programmed in one cycle with multiple calls, it must be ensured that

the block call that will implement the selection of geometry axes is called first in the cycle.

With these parameter settings, the signals are sent to the first mode group, the first channel and

all axes. In addition, the spindle override is transferred in the 4th axis/spindle interface. The feed

hold signal is passed to bit memory 22.0 and the spindle stop signal to data block DB2, data bit

151.0.

Reconnecting the axis selections

To ensure a flexible assignment of the axis selection keys to the appropriate axis or spindle,

FC19 needs not be modified or reprogrammed. The axis number simply has to be entered in

axis table starting from DB10.DBB8 as required.

Example

The spindle is defined as the 4th machine axis and is to be selected via axis key 9 (key R9 of the

R key group).

17.26 FC21: Transfer - data exchange NC/PLC

17.26.5

Function 3, 4: Fast data exchange PLC-NC

General

A separate, internal data area is provided as interface to allow the fast exchange of data between

the NC and the PLC. The interface encompasses 4096 bytes. PLC access operations (reading/

writing) are realized via FC21. The internal structure of the interface is solely defined by the user,

and must have precisely the same definition on the NC and PLC sides.

This data can be accessed by the NC program with the commands $A_DBB[x], $A_DBW[x],

$A_DBD[x], $A_DBR[x] (further information: List Manual, System Variables).

The concrete address in the data array is specified by a byte offset (0 to 4095) in parameter

"IVAR1". In this case, the alignment must be selected according to the data format, i.e. a DWORD

starts at a 4byte limit and a WORD at a 2byte limit. Bytes can be located at any offset within the

data field. Individual bits cannot be accessed. FC21 converts them over to a byte access. Data

type information and quantity of data are taken from the ANY parameter, transferred via S7Var.

Without additional programming-related measures, data consistency is only ensured for 1 and

2 byte access operations - both from the NCU and from the PLC. For 2-byte consistency this is true

only for the data type WORD or INT, but not for the data type BYTE.

In the case of longer data types or transfer of arrays which should be transferred consistently, the

semaphore byte must be used in parameter "IVAR2", which can be used by FC21 to determine

the validity or consistency of a block. This handling must be supported by the NC, i.e. in the NC

program, by writing or deleting the semaphore byte. The semaphore byte is stored in the same

data field as the user data.

The semaphore byte is identified by a value between 0 and 4095 in "IVAR2".

The PLC reads and writes to the semaphore byte via FC21 in the same call, in which the user data

should be transferred. The PLC programmer only has to define the semaphore variable in the

interface. For access from the NC via the NC program, the semaphore mechanism must be

programmed using individual instructions according to the flow chart shown below. The

sequence is different for reading and writing variables.

Only individual variables or arrays (fields) can be supported directly using the semaphore

technique. Transferring structures must be split up into individual jobs. Here, the user must

ensure data consistency of this structure by programming the appropriate semaphore

mechanism.

If "IVAR2" = -1 is set, data are transferred without a semaphore.

Block descriptions

17.27 FC22: TM_DIR - direction selection for tool management

Function

Referred to the location numbers, e.g. a tool magazine or revolver (indexing axis) block FC22

"TM_DIR" supplies the shortest path and direction of motion for positioning, based on the target

and current position.

Outputs

• Input FC22: "Start" = 1 ⇒ the outputs are cyclically updated.

• Input FC22: "Start" = 0 ⇒ the outputs are undefined.

Special positioning

For direction selection with special positioning (input FC22: "Offset" > 0) a new target position

is calculated from the target position, the offset for special positioning as well as the number of

magazines locations:

New_target position = ( target position - ( special position -1 ) ) neg. MODULO

number_of_magazine locations

The new target position corresponds to the location number at which the magazine must be

positioned so that the target position requested by the user corresponds to the location number

of the special position.

The directional optimization is active both with and without special positioning.

Call

The block must be called once with the appropriate parameter settings for each magazine.

17.28 FC24: MCP_IFM2 - transferring MCP signals to the interface

17.28

FC24: MCP_IFM2 - transferring MCP signals to the interface

Function

Block FC24 "MCP_IFM2" (M variant, e.g. MCP 310) is used for transferring data from the machine

control panel to the NC/PLC interface:

• Modes

• Axis selections

• WCS/MCS switchover

• Traversing keys

• Overrides or override simulation signals

• Key-operated switch position

The following specifications apply to the feedrate override, axis travel keys and INC keys

depending on the active mode or on the coordinate system selected:

• Feedrate override:

- The feedrate override is transferred to the interface of the selected channel and to the

interface of the axes.

- The feedrate override signals are transferred to the NC channel in addition to the "Rapid

traverse override" (DBB 5) interface byte if the "Feedrate override for rapid traverse

effective" HMI signal is set (exception: Switch setting "Zero"). "Rapid traverse override

effective" is also set with this HMI signal.

• Machine functions for INC and axis travel keys:

- When the MCS is selected, the signals are transferred to the interface of the selected

machine axis.

- When the WCS is selected, the signals are transferred to the geometry axis interface of the

parameterized channel.

- When the system is switched between MCS and WCS, the active axes are generally

deselected.

The associated LEDs on the machine control panel are derived from the acknowledgments from

the relevant selections.

Feedrate and spindle Start/Stop are not transferred to the interface, but output modally as a

"FeedHold" or "SpindleHold" signal. The user can link these signals to other signals leading to a

feed or spindle stop (this can be implemented, e.g. using the appropriate input signals in FC10:

AL_MSG). The associated LEDs are activated at the same time.

The spindle direction (+, -) is not switched directly either, but made available as output

parameter "SpindleDir". permitting, for example, FC18 to be parameterized. A spindle enable

signal is also switched via parameter "SpindleHold". One possible method of moving a spindle

directly is to preselect it as an axis so that it can be traversed via (axis) direction keys.

If the machine control panel fails, the signals it outputs are preset to zero; this also applies to

"FeedHold" and "SpindleHold" output signals.

FC24 or also FC19, FC25, FC26 can be called a multiple number of times in a single PLC cycle. In

this case, the first call in the cycle drives the LED displays. Furthermore, all actions of the

PLC

Function Manual, 10/2020, 6FC5397-0HP40-0BA1

Block descriptions

17.28 FC24: MCP_IFM2 - transferring MCP signals to the interface

parameterized block are carried out in the first call. In the following calls, only a reduced level of

processing of the channel and mode group interface takes place. The geometry axes are

supplied with directional data only in the first block call in the cycle.

Single block processing can be selected/deselected only in the first call in the cycle.

The second machine control panel can be processed if parameter "ModeGroupNo" has been

increased by B#16#10. When parameterizing, the HHU number is contained in the lower nibble

(lower 4 bits).

"BAGNo" = 0 or B#16#10 ⇒ mode group signals are not processed.

"ChanNo" = 0 ⇒ no processing of the channel signals.

The INC selections are transferred to the mode group interface. The activation for this

specification is done via the DB10.DBX57.0 (INC inputs in BAG area active) through this block

once after power up.

Furthermore, two machine control panels can be handled in parallel by this block. The block call

for the 2nd machine control panel in OB1 cycle must be set after the call of the 1st MCP. Support

for two MCPs is provided in the control panel blocks up to certain limits (support is not provided

as standard for mutual interlocking of axis selections with identical assignments on two MCPs).

Key-operated switch position

As of software version 4.5 SP2, the key-operated switch signals in the FC24 are also transferred

to the user interface (DBX56.5 to 7). This transfer is made independent of whether a keyswitch

is mounted on the MCP.

Note

For further information see "FC19: MCP_IFM - transfer of MCP signals to interface (Page 282)".

Flexible axis configuration

It is possible to be flexible in the assignment of axis selections or direction keys for machine axis

numbers.

Better support is now provided by the MCP blocks for the use of two MCPs, which are to run in

parallel, in particular for an application using two channels and two mode groups. Note that the

axis-numbers are also specified in the parameterized mode group number of the MCP block in

the axis tables of the relevant MCP.

To provide this flexibility, tables for axis numbers are stored in DB10.

For the 1st machine control panel (MCP) the table starts at byte 8 (symbolic name:

MCP1AxisTbl[1..22]) and for the second machine control panel (MCP) starting at byte 32

(symbolic name: MCP2AxisTbl[1..22]). The machine axis numbers must be entered byte by byte

here. It is permissible to enter a value of 0 in the axis table. Checks are not made to find illegal

axis numbers, meaning that false entries can lead to a PLC Stop.

For FC24, the maximum possible number of axis selections can also be restricted.

This upper limit is set for the first machine control panel in DB10.DBW30 (symbolic name:

MCP1MaxAxis) or for the second machine control panel in DB10.DBW54 (symbolic name:

MCP2MaxAxis) for the respective MCP.

The default setting is 0, corresponding to the maximum number of configured axes. The axis

numbers and the limit can also be adapted dynamically. Afterwards, a new axis must be selected

Block descriptions

17.28 FC24: MCP_IFM2 - transferring MCP signals to the interface

for FC24. Axis numbers may not be switched over while the axes are traversing the relevant

direction keys. The compatibility mode is preset with axis numbers 1 to 6 for both MCPs and

restricted to the configured number of axes.

Axis selection from the HMI

In addition to the 6 axis selection keys of the MCP, the active axis can also be selected in the HMI.

If an axis is being selected from the HMI, then no axes can be traversed using the direction keys.

Axis selection from the HMI is then only adopted for the MCP if the selected channel in the HMI

correlates with that at FC25. With axis selection from the HMI, an initial attempt is made as with

axis selection using the axis selection keys of the MCP, to find an assignment between the

selected axis number and the actual machine axis in the axis table of the NC-DB, refer to section

"Flexible axis configuration".

This means that when an axis is selected from the HMI, the same machine axis is selected as if

the corresponding axis selection key of the MCP had been selected. If an assignment is not

possible, then the axis number selected from the HMI is directly used as machine axis. As a

consequence it is possible to select axes that cannot be selected via the MCP.

Single block mode

Pressing the single block key activates the single block mode and, if the key is pressed again, the

single block mode is deactivated. If the mode is called several times for one MCP, the block

transfers single block mode state from the channel of the first call to the channels of the

subsequent calls.

block call for the second machine control panel in OB1 cycle must be set after the call for the 1st

MCP. Note that the axis numbers are also specified in the parameterized mode group number of

the MCP block in the axis tables of the relevant MCP.

To provide this flexibility, tables for axis numbers are stored in DB10.

For the 1st machine control panel (MCP) the table starts at byte 8 (symbolic name:

MCP1AxisTbl[1..22]) and for the 2nd machine control panel (MCP) it starts at byte 32 (symbolic

name: MCP2AxisTbl[1..22]). The machine axis numbers are entered here byte-by-byte. It is

permissible to enter a value of 0 in the axis table. Checks are not made to find illegal axis

numbers, meaning that false entries can lead to a PLC Stop.

The restriction of the possible number of axes at FC25 is realized using the 0-values in the axis

table. The axis numbers can also be adapted dynamically. During the manual traversing of axes

using the direction keys, the axis numbers must not be switched over. The compatibility mode

is preset with axis numbers 1 to 4 for both MCPs and restricted to the configured number of axes.

currently a machine axis is being moved via a traversing key.

Flexible axis configuration for the HT 8

The assignment of axis traversing keys to machine axes can be configured flexibly. Each pair of

axis traversing keys can be assigned any machine axis. If more than six machine axes are to be

used, the assignment can be changed dynamically. The assignment must not be changed while

axes are traversing. The assignment is made via the data block DB10. The number of the

machine axis that is to be selected by the ith axis traversing key pair of the first HT 8 is entered

in the assignment table starting from DBB8. The assignment for the key pairs of the second HT 8

is entered in DB10 from DBB32. If an entry of the assignment tables is set to 0, this means that

no axis can be moved using the associated key pair. The number of usable axis traversing key

pairs can be limited by the value DB10.DBW30 or DB10.DBW54. If the value 0 (default setting)

is used, all axis traversing key pairs to which a machine axis has been assigned can be used. The

machine axes 1 to 6 are preset for the axis traversing key pairs 1 to 6 (see PLC manual, Chapter

"Flexible axis configuration").

Flexible axis configuration for the HT 10

Contrary to the HT 8, the HT 10 only has one plus and one minus key for traversing. There is also

a key for rapid traversing. The active axis, to which these traversing signals refer, must be

selected at the HMI (Smart Operate).

17.30 FC26: HPU_MCP - Transfer of the HT 8/HT 10 signals to the interface

If an axis is being selected from the HMI, then no axis can be traversed using the direction keys.

Axis selection from the HMI is then only adopted for the MCP if the selected channel in the HMI

correlates with that at FC26.

If FC26 is called for an HT 10 with ChanNo := 0, no axes can be traversed as the current axis

cannot be determined from the channel DB. (See PLC manual chapter "Selection of JOG axis via

HMI")

17.30 FC26: HPU_MCP - Transfer of the HT 8/HT 10 signals to the interface

Transfer of the traversing key signals depending upon the active coordinate system

The traversing key signals for 6 axes lie in the HT 8 input data area below:

• IB n + 2, Bit 0 - Bit 5 (positive traversing direction)

• IB n + 3, Bit 0 - Bit 5 (negative traversing direction)

The switchover of the coordinate system is done via the input signal:

• IB n + 0, Bit 0 (MCS/WCS)

The input signal is evaluated in FC26 with the help of the edge trigger flag. The active coordinate

system is shown in the following output signal:

• QB n + 0, Bit 0 (MCS/WCKS) with 0 = MCS, 1 = WCS

In case of active MCS the traversing key signals of the axes 1 - 6 are transferred in the axis-

specific interfaces (DB31,

DBX4.6 and DBX4.7 (traversing key +/-)) of the axes specified in the

machine axis tables (DB10.DBB8 to DBB13 or DBB32 to DBB37).

For HT 8 with active WCS, it is assumed that the axes 1 - 3 of the machine axis table are geometry

axes. For the traverse key signals with HT 8, the following applies:

• The traverse key signals of axes 1 - 3 (EB n + 2 / 3, bit 0 - bit 2) are transferred into the interface

of the geometry axes in DB21,

DBB12 + (n * 4), with n = 0, 1, 2), bit 6 and bit 7 (traverse

keys +/-) of the channel specified with parameter "ChanNo".

The assignment of the traversing key signals of axes 1, 2 and 3 to the geometric axes 1, 2 and

3 of the channel is permanent and may not be changed.

• The traverse key signals of axes 4 - 6 (EB n + 2 / 3, bit 3 - bit 5) are transferred into the axis-

specific interfaces (DB31,

DBX4.6 and DBX4.7 (traverse keys +/-)) of axes 4 - 6 entered in

the machine axis table (DB10.DBB11 to DBB13 or DBB35 to DBB37).

For HT 10, only one geometry axis which was selected from the HMI can be traversed

respectively.

The axis traverse signals (+/- and rapid traverse) for HT 10 relate to a machine axis or a geometry

axis, depending on which axis was selected in the HMI and whether WCS or MCS is active. See

also "Flexible axis configuration for the HT 10".

No traversing of machine axes in WCS

In case of active WCS (AB n + 0, Bit 0 = 1) the traversing of the machine axes can be locked. For

this, the following output signals are to be set in the PLC user program:

• QB n + 3, Bit 7 = 1 (For WCS: no machine axes)

Requirement to the FC26, not to transfer any traversing key signals for the machine axes. The

traversing key signals for the axes 1 - 3 of the machine axis table are transferred to the

geometric axes 1 - 3 of the specified channel. The traversing key signals for the axes 4 - 6 of

the machine axis table are not transferred.

• QB n + 2, Bit 6 (axes 7 - n selected)

Requirement to the FC26 not to transfer any traversing key signals, since the axes 1 - 6 of the

machine axis table are switched over. The axes 1 - 3 are thus not geometric axes but machine

axes.

Block descriptions

17.30 FC26: HPU_MCP - Transfer of the HT 8/HT 10 signals to the interface

Feedrate override

The value of the HT 8 override switch is transferred as feedrate override in the channel-specific

interface DB21,

DBB4 (feedrate override) of the programmed channel (parameter: "ChanNo")

and in the axis-specific interfaces DB31,

DBB0 (feedrate override) of the axes programmed in

the table DB10.DBB8 to DBB13 (machine axis number).

Rapid traverse override

If for the programmed channel (parameter: "ChanNo") the signal DB21,

DBX25.3 = 1

(feedrate override for rapid traverse) is set, the value of the HT 8 override switch is sent as a rapid

traverse override to its channel-specific interface in DB21,

DBB5 (rapid traverse override) and

the signal DB21,

DBX6.6 = 1 (rapid traverse override active) is also set.

Machine function INC

The HT signals of the machine function INC are transferred differently depending upon the active

coordinate system MCS or WCS:

• Active coordinate system: MCS

The selected machine function INC is transferred for all 6 axes in the axis-specific interfaces

in DB31,

DBX5.0 to DBX5.5 (machine function) of the axes programmed in the table in

DB10.DBB8 to DBB13 (machine axis numbers) .

• Active coordinate system: WCS

For the axes 1 to 3 the signals of the machine function INC are transferred in the channel-

specific. Interface in DB21,

DBX13.0 to DBX13.5 (machine function) of the programmed

channel (Parameter: "ChanNo").

For the axes 4 to 6 the signals of the machine function INC are transferred in the channel-

specific. interfaces in DB31,

DBX5.0 to DBX5.5 (machine function) of the axes

programmed in the table in DB10.DBB11 to DBB13 (machine axis numbers).

The selection signals of the INC machine functions are transferred in the mode group-specific

interface DB11.DBB 2 + (n * 20), bit 0 to bit 5 (with n = 0, 1, 2, ...). The FC26 informs the NC about

the activation of the mode group interface for the INC machine functions once after power-up

with DB10.DBX57.0 (INC inputs active in the mode group area).

Handwheel selection

The hand-wheel selection signals are evaluated by HMI and transferred to the corresponding NC/

PLC interface signals of the machine or geometric axes:

• Geometry axes: DB21, ... DBB 12 + (n * 4), bit 0 to bit 2 (with n = 0, 1, 2)

• Machine axes: DB31,

DBX4.0 to DBX4.2

Requirement: FB1 parameters: "HWheelMMC" = TRUE

Multiple call in one PLC cycle

To transfer signals to multiple mode groups, channels or axes, the block can be called multiple

times with the corresponding parameters, "BAGNo" and "ChanNo".

Block descriptions

17.30 FC26: HPU_MCP - Transfer of the HT 8/HT 10 signals to the interface

In the first call of the block for an HT 8 or the HT 10, all signals are transferred to the data blocks

of the NC/PLC interface and the output signals are controlled. Only the signals to mode groups

and channels are now transferred for the following calls in the same PLC cycle.

Processing of two MCP

If the function FC26 is called twice for two MCP in the cyclic sequence of the PLC program

(organization block OB1), the call for the second MCP must be made after the call for the first

MCP.

Note

If an axis can be traversed from two MCP, then the implementation of a mutual interlocking is

the responsibility of the user (machine manufacturer).

Failure of the MCP of the HT

In case of failure of the MCP of the HT, all the input signals are set to the value 0. That means that

a current traversing movement is stopped and automatically continued when the HT is

connected again. It is the responsibility of the user (machine manufacturer) to comply with

safety regulations, e.g. by triggering a PLC stop when a failure of the MCP of the HT is detected.

The job is started with a rising edge at parameter "Req". The values at the input parameters are

applied and remain valid for the entire duration of the job.

The block must be called until it reports "done" or "error".

The job cannot be aborted.

After the end of the job, a rising edge at "Req" is required to start a new job.

Multiple, parallel calls are not allowed, even for different MCPs.

① "Done" and "Error" are reset with a falling edge at "Req".

② The functionality of the FB is not stopped with a falling edge at "Req". If the input "Req" is reset

before the output "Done" is set, the output "Done" is only set for one cycle.

③ If "Req" is already FALSE, then "Done" and "Error" are only active for one cycle.

④ A new job is requested with a rising edge at "Req" while the block is still being processed ("Busy"

= TRUE).

The old job is ended with the parameters active at the beginning of the job.

Application example: Setting the key color of a modular MCP

Colors that depend on the status can be assigned to the keys of a modular MCP. Possible statuses

are active and inactive.

The data record passed on to parameter "Record" must correspond to the format expected for the

configuration of the modular MCP. For this purpose, use the data type

"ModularMcpKeypadRecord" provided in the library. The hardware and data assignment of the

MCP are described in the Operating Components Manual Modular MCPs.

To assign a color to the keys, follow these steps:

• Transfer the value 128 at parameter "RecNum".

• Configure the variables of the data record that you transfer to parameter "Record".

"Version" must be set to 16#10

Specify keys using the index referring to specific keypad

Colors for the relevant key as RGB code (0 to 255)

• Specify the number of the keypad that you want to configure at parameter "SlotNum".

• Configure the remaining parameters of the FB.

with another station via the integrated "CP 840D sl." This station must be configured in STEP 7,

"NetPro."

In the basic program, this function is available as a function block FC1005. This is roughly

equivalent to function block FC5 in the "SIMATIC_NET_CP" library.

The TCP, UDP, and ISO-on-TCP protocols are supported.

Note

Smaller volume of transmittable data with SINUMERIK CP and UDP or ISO-on-TCP protocol
