Note

Industrial security

Siemens provides products and solutions with industrial security functions that support the

secure operation of plants, systems, machines and networks.

In order to protect plants, systems, machines and networks against cyber threats, it is

necessary to implement - and continuously maintain - a holistic, state-of-the-art industrial

security concept. Siemens’ products and solutions constitute one element of such a concept.

Customers are responsible for preventing unauthorized access to their plants, systems,

machines and networks. Such systems, machines and components should only be connected

to an enterprise network or the Internet if and to the extent such a connection is necessary

and only when appropriate security measures (e.g. firewalls and/or network segmentation) are

in place.

For additional information on industrial security measures that may be implemented, please

visit:

Industrial security (http://www.siemens.com/industrialsecurity )

Siemens’ products and solutions undergo continuous development to make them more secure.

Siemens strongly recommends that product updates are applied as soon as they are available

and that the latest product versions are used. Use of product versions that are no longer

supported, and failure to apply the latest updates may increase customer’s exposure to cyber

threats.

A4: Digital and analog NC I/O for SINUMERIK 840D sl

2.1

Introduction

Functions

I/O modules can be connected to a SINUMERIK 840D sl via PROFIBUS or PROFINET.

Normally, the PLC user program uses the appropriate digital or analog inputs and outputs for

access. The "Digital and analog NC I/O for SINUMERIK 840D sl" function enables access to

the inputs/outputs of the I/O modules via system variables of compile cycles directly from the

NC (part programs, synchronized actions and compile cycles). This I/O is referred to as the

NC I/O in the following.

Three different functions are available for compatibility reasons:

1. Direct I/O access without PLC (Page 58)

Avoiding the PLC, the control internal images of the inputs/outputs of the I/O modules can

be accessed directly from the NC.

This is currently the function with the highest performance with regard to the quantity

structure and response time.

2. Direct I/O access via PLC (Page 53)

The read and write requests of the inputs/outputs of the I/O modules are written from the

NC via the interface to the PLC. An interrupt is then triggered on the PLC. The requests

from the PLC are processed as part of the interrupt processing.

From the quantity structure, the function is equivalent to that described above. However,

the response time is not as good.

3. Indirect I/O access via PLC (Page 32)

The read and write requests of the inputs/outputs of the I/O modules are written from the

NC via the interface to the PLC. The requests are processed cyclically in the OB1 cycle.

This function has the lowest performance with regard to the quantity structure and response

time.

Requirements

● The PROFIBUS/PROFINET I/O modules of the NC I/O must be connected and ready to

use.

● The HW configuration of the PROFIBUS/PROFINET I/O modules of the NC I/O has been

performed with the SIMATIC S7 Manager or HW Config and loaded to the PLC.

Function Manual, 12/2018, A5E40874029B AB

A4: Digital and analog NC I/O for SINUMERIK 840D sl

2.2 Indirect I/O access via PLC

Monitoring

The following monitoring functions are active for the NC I/Os:

● Ramp-up:

- Check for consistency of the I/Os detected on the PLC and the NC I/O parameterized

in the machine data.

● Cyclic operation:

- Sign-of-life monitoring in interpolation cycles

- Module monitoring in interpolation cycles

- Temperature monitoring

In the event of an error, the DB10.DBX104.7 "NC ready" signal is reset and an alarm is

displayed.

Response to faults

The digital and analog outputs of the NC I/O are switched to a safe status (0 V) in the event

of faults (e.g. NC ready = 0), for errors in the NCU or power failures.

Application

The NC I/O is used, for example, by the following NC functions:

● Several feedrate values or auxiliary functions in one block

● Rapid retraction on final dimension

● Axis-specific delete distance-to-go

● Program branches

● Rapid NC Start

● Analog calipers

● Position switching signals

● Punching/nibbling functions

● Analog-value control

Four digital inputs and outputs of the X142 interface are available as so-called fast NC I/O.

They can be read or written via the first address byte and via the $A_IN[1...4] and $A_OUT[1...4]

system variables.

2.2 Indirect I/O access via PLC

I/O modules can also be connected to the PROFIBUS DP/MPI interfaces X126 and X136. This

enables the number of digital and analog NC inputs/outputs to be expanded by 32 digital and

8 analog inputs and outputs respectively. These NC inputs/outputs are called external NC I/

Os in the following.

Parameterization

Machine data

Number of active NC I/Os

The number of active or from the NC usable digital NC I/O bytes are set in the following machine

data:

● Number of digital NC input bytes

MD10350 $MN_FASTIO_DIG_NUM_INPUTS = <number>

● Number of digital NC output bytes

MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS = <number>

The number of active or from the NC usable analog I/Os are set in the following machine data:

● Number of analog NC inputs

MD10300 $MN_FASTIO_ANA_NUM_INPUTS = <number>

● Number of the analog NC outputs

MD10310 $MN_FASTIO_ANA_NUM_OUTPUTS = <number>

The I/Os do not have to actually exist in the hardware. In this case, the signal states or the

analog values are set to "zero" in a defined way inside the NC.

The values present at the I/O inputs can be changed from the PLC user program before they

are read by the NC.

Overwrite

If, in the interface, a bit is set, then for the corresponding output, instead of the value written

using system variables $A_OUT, the setting value specified from the PLC user program is

used. The value written via system variables $A_OUT is then lost.

If the bit in the interface is reset, then the actual value is kept at the hardware output.

Setting value

Using the setting value, the PLC user program can specify a defined output value. In order

that the setting value becomes active, it must be activated via the interfaces for "Overwrite" or

"Target".

Setpoint

The actual NC output value can be read in the PLC user program via the setpoint.

Note

Different values

The value in the "Setpoint" interface can, as a result of the various subsequent influencing

possibilities, have a different value than that available at the NC output.

Target

If, in the interface, a bit is set, then for the corresponding output, instead of the NC output

value, the setting value specified by the PLC user program is used. The actual NC output value

is kept.

If a bit is reset in the interface, then the last NC output value becomes active again.

Special cases

● If several output bits are assigned to the same input bit, then the one with the highest MD

index becomes effective.

● If inputs or outputs are specified which do not exist or are not activated, then the assignment

is ignored without an alarm. Checking of the active bytes of the NC I/Os is performed via

the entries in machine data:

MD10350 $MN_FASTIO_DIG_NUM_INPUTS

MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS

Defining assignments

The assignments are specified via machine data:

MD10361 $MN_FASTIO_DIG_SHORT_CIRCUIT[n]

n: can accept values 0 to 9, so up to 10 assignments can be specified.

Two hexadecimal characters are provided for specifying the byte and bit of an output and an

input.

Comparator inputs

Function

Two internal comparator input bytes, each with eight comparator inputs, are available in

addition to the digital and analog NC inputs. The signal state of the comparator inputs is

generated on the basis of a comparison between the analog values present at the fast analog

inputs and the threshold values parameterized in setting data.

The $A_INCO[<n>] system variable allows the signal state (i.e. the result of the comparison)

of comparator input [<n>] to be scanned directly in the part program.

Applies for index <n>:

<n> = 1 ... 8

For comparator byte 1

<n> = 9 ... 16

For comparator byte 2

Terms

In this description, the terms comparator inputs (with index <n>; value range of <n>: 1 ... 8 or

9 ... 16) and comparator input bits (with index ; value range of : 0 ... 7) are used.

They are related as follows:

For <n> = 1 ... 8:

Comparator input <n> is equivalent to comparator input bit

= <n> - 1.

For <n> = 9 ... 16:

Comparator input <n> is equivalent to comparator input bit

= <n> - 9.

Example: Comparator input 1 is equivalent to comparator input bit 0.

Assignment of the analog inputs

The following machine data is used to assign an analog input to input bit of comparator

byte 1:

MD10530 $MN_COMPAR_ASSIGN_ANA_INPUT_1[]

Example:

MD10530 $MN_COMPAR_ASSIGN_ANA_INPUT_1[0] = 1

MD10530 $MN_COMPAR_ASSIGN_ANA_INPUT_1[1] = 1

MD10530 $MN_COMPAR_ASSIGN_ANA_INPUT_1[7] = 7

Analog input 1 acts on input bits 0 and 1 of comparator byte 1.

Analog input 7 acts on input bit 7 of comparator byte 1.

The analog inputs for comparator byte 2 are assigned with the machine data:

MD10531 $MN_COMPAR_ASSIGN_ANA_INPUT_2[]

2.2 Indirect I/O access via PLC

Comparator settings

The settings for the individual bits (0 to 7) of comparator byte 1 or 2 are parameterized via the

machine data:

MD10540 $MN_COMPAR_TYPE_1 (parameter assignment for comparator byte 1)

MD10541 $MN_COMPAR_TYPE_2 (parameter assignment for comparator byte 2)

The following settings are possible:

● Comparison type mask (bits 0 … 7)

The type of comparison condition is defined for each comparator input bit:

Bit = 1:

Associated comparator input bit is set to "1" if:

Analog value ≥ threshold value

Bit = 0:

Associated comparator input bit is set to "0" if:

Analog value < threshold value

● Output of the comparator input byte via digital NC outputs (bits 16 … 23)

The comparator bits can also be output directly via the digital NC outputs byte-by-byte. This

requires specification in this byte (bits 16 … 23) of the digital NC output byte to be used.

Byte = 0:

No output via digital NC outputs

Byte = 1:

Output via digital onboard NC outputs 9 … 16

Byte = 2:

Output via external digital NC outputs 17 … 24

Byte = 3:

Output via external digital NC outputs 25 … 32

Byte = 4:

Output via external digital NC outputs 33 … 40

● Inversion mask for output of the comparator input byte (bits 24 … 31)

For every comparator signal it is also possible to define whether the signal state to be output

at the digital NC output is to be inverted or not.

Bit = 1:

Associated comparator input bit is not inverted.

Bit = 0:

Associated comparator input bit is inverted.

Threshold values

The threshold values used for comparisons on comparator byte 1 or 2 must be stored as setting

data. A separate threshold value must be entered for each comparator input bit (with

= 0 … 7):

SD41600 $SN_COMPAR_THRESHOLD_1[]

SD41601 $SN_COMPAR_THRESHOLD_2[]

2.2 Indirect I/O access via PLC

Comparator signals as digital NC inputs

All NC functions that are processed as a function of digital NC inputs can also be controlled

by the signal states of the comparators. The byte address for comparator byte 1 (HW byte 128)

or 2 (HW byte 129) must be entered in the machine data associated with the NC function

("Assignment of hardware byte used").

Example:

"Multiple feedrates in one block" NC function

Entry in channel-specific machine data:

MD21220 $MC_MULTFEED_ASSIGN_FASTIN = 129

This activates various feedrate values as a function of the status of comparator byte 2.

Transfer times

● Transfer of the output data from the NC to the output modules

- The output data is transferred from the NC to the output modules at the end of the current

interpolator cycle.

- The transfer is only performed when at least one output data item has been written in

the current interpolator cycle.

● Transfer of the input data from the input modules to the NC

- Time within which the cyclic request for the update of the input data (input image of the

modules → NC input data) from the NC to the PLC is sent, can be set via the machine

data:

- MD10398 $MN_PLCIO_IN_UPDATE_TIME = <update time>

- The parameterized update time is rounded up internally to the next highest multiple of

an interpolator cycle. With update time = 0, the request is transferred to the PLC in each

interpolation cycle.

- The request for the update of the input data is sent to the PLC at the end of the

parameterized interpolation cycle.

- The updated input data is available at the earliest in the following interpolation cycle.

Selection of the storage format (little/big endian)

A total of 16 KB is available for the data transfer between the NC and PLC for all NC channels.

These areas have to be managed by the user (i.e. no overlapping of the variables, not even

across channel borders).

The display of the variables within these areas depends on the setting in the machine data:

2.3.3

Supplementary conditions

Several slots

If several slots form an input or output range of the PLC I/O used directly by the NC, the address

range of the slots must be configured as a continuous range without gaps.

Parallel writing of the NC and PLC

Parallel writing of I/O outputs by the NC via direct access over the PLC and from the PLC user

program results in a random, mutual overwriting of the output values. The application is

therefore not permitted, but cannot be prevented on the control.

Time response

The time when the data is read in from the PLC I/Os is not synchronized with the time when

the data is made available to the part program via system variables!

Data transfer

● The output of the output data on the PLC I/O is always for all parameterized output data,

even when only one output data item was written for each system variable.

● If several system variables are assigned values simultaneously, it is not certain that they

are transferred in the same interpolation cycle.

I/O range

If slots are configured for a PROFIBUS/PROFINET slave used for the NC I/O in such a way

that they are in ascending order without gaps, they are called the I/O range in the following.

An I/O range is therefore characterized by:

● Logical start address: Logical start address of the first slot of the PROFIBUS/PROFINET

slave

● Length: Total length of all slots used for the PROFIBUS/PROFINET slave

The parameterization of the logical start address and the length of the I/O range is performed

in the NC via machine data (see "Parameter assignment (Page 60)").

Reading/writing

Part programs / synchronized actions: System variables

The reading/writing of the NC I/O is performed in the NC via system variables in the interpolator

cycle. The writing on the NC I/O is performed after the interpolation cycle.

Data consistency: Interpolator cycle

See "System variables (Page 61)".

Parallel reading/writing

Reading

Parallel reading through compile cycles and part programs / synchronized actions on input

data of the same I/O range is possible. Write access to the NC I/O is performed in different

ways.

● The data consistency is ensured.

● The data equality during an interpolator cycle is not ensured.

Writing

Parallel writing through compile cycles and part programs / synchronized actions on output

data of the same I/O range is not possible.

Logical start addresses of the I/O ranges

The logical start addresses of the I/O ranges used are set via the following machine data:

● Logical start addresses of the input range 1, 2, ... m:

MD10500 $MN_DPIO_LOGIC_ADDRESS_IN[ <n>] = <logical start address> ; with <n> =

0, 1, 2, ... (m - 1)

MD10510 $MN_DPIO_LOGIC_ADDRESS_OUT[ <n>] = <logical start address> ; with <n>

= 0, 1, 2, ... (m - 1)

The following must be taken into account for logical start addresses within the PLC process

image (see References):

- Input slots: Reading from the NC also possible

- Output slots: Writing from the NC not permitted ⇒ alarm after run-up of the NC

Note

I/O ranges for the write access (MD10510) on the PROFIBUS I/O must not be in the range

of the process image, e.g. PLC 317-3, output addresses 0 - 1023.

For PROFINET I/O, these I/O ranges must be assigned in the process image to "TPA 2";

the configuration is realized using the synchronous cycle interrupt "NC".

Lengths of the I/O ranges

The lengths of the I/O ranges used are set via the following machine data:

● Length of the input range 1, 2, ... m:

MD10501 $MN_DPIO_RANGE_LENGTH_IN[ <n> ] = <length>; with <n> = 0, 1, 2, ... (m -

If the value 0 is entered as length, the length of the first user data slot found under the specified

start address (MD10500/MD10510) is set internally as the length of the I/O range.

Valid I/O ranges for part programs / synchronized actions

Each system variable is a 32-bit bit array. Each bit is assigned to an I/O range.

Bit <n> ≙ machine data index <n> ≙ I/O range <n+1>

Bit <n> == 1 ⇒ The I/O range <n+1> is valid. Reading/writing via part programs / synchronized

actions

2.4 Direct I/O access without PLC

System variable

Type

Meaning

<n> = index of the I/O range

State

0: I/O range has not been configured

1: I/O range could not be activated

2: I/O range is available

3: I/O range is currently not available

Length of an I/O range

The configured length of an I/O range can be read via the following system variables.

System variable

Meaning

$A_DP_IN_LENGTH[<n>]

Reading the length of the input data range

$A_DP_OUT_LENGTH[<n>]

Reading the length of the output data range

<n> = index of the I/O range

Supplementary conditions

● A preprocessing stop is triggered in the channel when reading/writing from a part program.

● To ensure data consistency during programming from the part program and the

synchronized actions, the PROFIBUS I/O data is accessed which is kept consistent for the

respective IPO cycle.

● If the same PROFIBUS I/O data is to be write-accessed several times within an interpolation

cycle (e.g. synchronized actions, access from different channels, etc.), then the data of the

last write access is valid.

● The PROFIBUS I/O data to be written is output at the PROFIBUS I/O only after the

corresponding IPO cycle.

● The (RangeOffset) indicates the place (byte offset) within the I/O range as of which

the data access is to be started. Data types can be read/written at any byte offset within

the I/O range. Read/write accesses which exceed the configured limits of the respective I/

O range are rejected with the generation of an alarm (17030).

● Via the machine data MD10502 $MN_DPIO_RANGE_ATTRIBUTE_IN or MD10512

$MN_DPIO_RANGE_ATTRIBUTE_OUT (see "Parameter assignment (Page 60)"), the

display format (little/big endian) for $A_DPx_IN[<n>,] or $A_DPx_OUT[<n>,]

system variables can be defined for the read/write direction as well as for each individual

I/O range.

2.4.4

Supplementary conditions

Parallel writing of the NC and PLC

Parallel writing of I/O outputs by the NC via direct access and from the PLC user program

results in a random, mutual overwriting of the output values. The application is therefore not

permitted, but cannot be prevented on the control.

2.4 Direct I/O access without PLC

Life beat monitoring

At the start of an interpolator cycle, a check is made for each I/O range whether the sign-of-

life of the associated slot or I/O range has failed. If this is the case, alarm 9050 or 9052 is

displayed.

Effects:

● The part program processing is not stopped.

● When the sign-of-life returns, the alarm is cleared automatically.
