Abnormality data

If an abnormality occurs in the input data or in the module, the DI13 bit

(status signal) becomes "1", resulting in the display changing from

temperature input data to abnormality data. Abnormality data is

assigned to these bits as listed below:

DI00 : CH1 input out of scale--the current temperature falls

outside the measurable range.

DI01 : CH1 input burn-out--the cable or connector has been

detached.

DI02 : CH3 input out of scale--the current temperature falls

outside the measurable range.

DI03 : CH3 input burn-out--the cable or connector has been

detached.

DI04 : Cold-junction abnormality (only for thermocouple-type

input module)--the temperature of the terminal board unit

falls outside the measurable range.

DI05 : System error--the internal circuit is abnormal.

DI06 : Wrong module--other than the correct module has been

installed.

Temperature input data

The temperature input data is in binary. It is ten times the actual

temperature.

Example

(41F3h → 0499 → 49.9°C)

The highest three bits are status signals.

For a thermoresistance-type module (ATI04A), the DI28 bit is a sign bit.

(Negative data is represented in two's complement.)

Example

(5FFBh → -0.5°C)

The highest three bits are status signals.

Abnormality data

If an abnormality occurs in the input data or the module, the DI29 bit

(status signal) is set to "1", resulting in the display changing from

temperature input data to abnormality data. Abnormality data is

assigned to these bits as listed below:

DI16 : CH2 input out of scale--the current temperature falls

outside the measurable range.

DI17 : CH2 input burn-out--the cable or connector has been

detached.

DI18 : CH4 input out of scale--the current temperature falls

outside the measurable range.

DI19 : CH4 input burn-out--the cable or connector has been

detached.

DI20 : Cold-junction abnormality (only for thermocouple-type

input module)--the temperature of the terminal board unit

falls outside the measurable range.

DI21 : System error--the internal circuit is abnormal.

DI22 : Wrong module--other than the correct module has been

installed.

When using the standard-type optical I/O Link adapter

(A13B-0154-B001):

Up to 5 partitions (I/O Link master -- group #0 -- group #1 -- ... --

group #15) can be configured with optical fibers.

Use electrical cables for the K1X in the other partitions.

When using the high-speed response type optical I/O Link adapter

(A13B-0154-B002):

The A13B-0154-B002 performs optical-electrical conversion

faster than the A13B-0154-B001.

All (16) partitions (master -- group #0 -- group #1 -- ... -- group

#15) can be configured with optical fiber.

NOTE

1 When using an optical fiber for I/O Links, use optical I/O Link adapters conforming to

the same specification on both ends of the optical fiber.

2 When using the high-speed response type optical I/O Link adapter

(A13B-0154-B002), do not use any optical fiber cable other than the

A66L-0001-0026.

When using the standard-type optical I/O Link adapter (A13B-0154-B001), either of

the optical fiber cables A66L-0001-0009 and A66L-0001-0026 can be used.

3 If 6 or more partitions of an I/O Link are configured with optical fibers, using the

standard-type optical I/O Link adapter even in one of these partitions disables the I/O

Link from operating normally.

When using optical fibers in 6 or more partitions, do not use the standard-type optical

I/O Link adapter; use only the high-speed response type optical I/O Link adapter.

Parts required per optical I/O Link partition

10.7.2 Notice of Optical Fiber Cable Handling

(1) Even though reinforcing cover used on the optical fiber code has

enough mechanical strength, be sure not to be damaged by heavy

materials drop.

(2) Detaching and attaching of optical connector should always be

made by touching connector. Optical fiber code should not be

touched when replacement.

(3) Optical connector is automatically locked with upper side lock

levels after being connected. It is impossible to pull out the

connector without releasing the lock levers.

(4) Optical connector cannot be connected oppositely. Be sure the

connector direction when connection is done.

(5) Optical connector should be processed as follows before laying of

optical fiber cable.

Fix a reinforcing cover to a wire with hook or tension member by a

tape.

At laying hook the wire or pull the tension member taking enough

care that optical connector does not receive pulling strength.

(6) Reinforcing cover is fixed to cable lamp so that optical fiber cable

could not weigh directly the connecting part of connector.

(7) Notice that optical connector's chip is clear.

The attached protect cap must be always put on when optical

connector is not used.

Remove dirty with a clear tissue or absorbent cotton (cotton with

ethyl alcohol is applicable). No other organic solvent than ethyl

alcohol cannot be used.

10.7.4 Relay Using an Optical Fiber Junction Adapter

(1) External view of an optical fiber junction adapter

(2) Example of the use of an optical fiber junction adapter

Optical fiber junction adapter

Specification: A02B-0094-K841

NOTE

Up to one relay points are permitted.

When the high-speed response type optical I/O Link

adapter is used, however, it is impossible to use the

optical fiber junction adapter.

(3) Installing the optical fiber junction adapter

The optical fiber junction adapter should be installed within a cabinet,

as a rule. If it is impossible to avoid installing it within a cabinet, protect

the adapter and the optical cable portions (such as connectors and

cords) not covered with reinforcement coating from the outside air by,

for example, covering them with packing.

(4) Environmental resistance of the optical fiber junction adapter

• The optical fiber junction adapter is not waterproof. Even when

optical cables are attached to both ends of the adapter, there are

very small gaps in the linked portions, so water resistance can not

be expected.

•

When optical cables are attached to both ends of the junction

adapter installed in a normal environment

(such as within a

cabinet), it is unlikely that dust will penetrate between the adapter

and optical fiber to the degree that it may hamper normal optical

linkage. If one or both ends of the adapter are left open, dust and

dirt may accumulate even when the adapter is in a normal

environment (such as within a cabinet). The dust and dirt on the

adapter ends is likely to hamper normal optical linkage when the

optical cables are attached. In such a case, clean the junction

adapter and the optical connector using the optical fiber junction

adapter cleaning method described below.

•

Do not allow cutting fluid to splash over the adapter or those

optical cable portions (such as connectors and cords) that are not

covered with reinforcement coating. If the inside of the adapter

and fiber end surfaces are contaminated with cutting fluid, a

malfunction may occur.

(3) Cleaning

If the optical fiber junction adapter, optical-to-electrical conversion

module, and optical cable are soiled, clean them according to the

following procedures.

• Cleaning the optical

fiber

junction

adapter

and

optical-to-electrical conversion module

First, clean the entire housing by wiping it with a cloth moistened

with, or by washing it in, ethyl alcohol or HCFC141B (alternative

CFC; High Shower spray can DS-2168, manufactured by Sun

Hayato). Similarly, wash the two sleeves in the adapter or wipe

them with a cotton swab or the like.

• Cleaning optical cables

For the optical cables, it is important to clean the connectors at

their ends. Any soiling on the optical fiber end surfaces will

hamper optical transmission, resulting in a malfunction. Wipe the

optical fiber end surfaces

(that is, the ferrule end surfaces)

thoroughly with a soft, clean cloth (like gauze) moistened with

ethyl alcohol or HCFC141B, in the same way as described above.

The use of cotton swabs may prove convenient. The fiber end

surfaces of low-loss optical cables are lower than the ferrules. To

remove any soiling from the fiber end surfaces completely, push

the cotton swab or gauze into the depressions all the way through

while rotating the ferrule. If the ferrules and optical connectors are

contaminated with oily substances, and they may extend over a

cleaned fiber end surface when it is attached to the

optical-to-electrical conversion module, it is a good idea to wash

them before wiping the optical fiber end surfaces, using the

procedure stated above.

Cable

Maximum transmission distance by optical fiber junction cable is

shown below:

The maximum transmission distance varies depending on the number of

relay points supported by optical fiber junction adapters. When the

high-speed response type optical I/O Link adapter is in use, no optical

fiber junction adapter can be used.

11.I/O Link DUMMY UNIT

11.1

OVERVIEW

If a slave unit (such as the FS0, Power Mate, I/O Unit-MODEL A, or

connection unit) is removed from the FANUC I/O Link ^(Note), the group

number for those that followed the removed slave unit changes. So, it

becomes necessary to change the PMC assignment. However,

connecting a FANUC I/O Link dummy unit in place of the removed

slave unit makes it unnecessary to change PMC assignment.

This chapter describes the electrical and structural specifications that

apply to the FANUC I/O Link dummy unit when it is connected to the

FANUC I/O Link.

Specification: A13B-0167-B001

NOTE

The FANUC I/O Link is a serial interface for

connecting the CNC or cell controller to the I/O

Unit-MODEL A, Power Mate, or other units for

high-speed transfer of I/O signals (bit data).
