SAFETY PRECAUTIONS

(Read these precautions before using this product.)

Before using this product, please read this manual and the relevant manuals carefully and pay full attention

to safety to handle the product correctly.

The precautions given in this manual are concerned with this product only. For the safety precautions of the

programmable controller system, refer to the user’s manual for the CPU module used.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION"

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to

serious consequences.

Observe the precautions of both levels because they are important for personal and system safety.

Make sure that the end users read this manual and then keep the manual in a safe place for future

reference.

[Design Precautions]

WARNING

When a communication error occurs on PROFIBUS-DP, the status of the faulty station is as shown

below.

Create an interlock circuit in the sequence program using the communication status information to

ensure the system operates safely (Input X1, buffer memory 5A20Hto 5B19H(23072 to 23321)).

An erroneous output or malfunction may cause accidents.

(1) The QJ71PB92V holds the input data before the communication failure.

(2) When the QJ71PB92V has gone down, the output status of each DP-Slave is dependent on the

QJ71PB92V parameter setting on GX Configurator-DP.

(3) When a DP-Slave has gone down, the output status of the other DP-Slaves is dependent on the

QJ71PB92V parameter setting on GX Configurator-DP.

Do not output the "use prohibited" signal as the output signal to an intelligent function module from

the programmable controller CPU.

Doing so may cause malfunction of the programmable controller system.

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions,

resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions,

resulting in minor or moderate injury or property damage.

A- 2

[Design Precautions]

WARNING

When a stop error has occurred to the CPU module, the communication status varies depending on

the error time output mode setting of GX Works2 as shown below.

Set the communication status for when a stop error has occurred to the CPU module according to

the system specifications.

Note that, if the QJ71PB92V is mounted to a redundant system, it operates as described in (1) below

regardless of the setting.

(1) When "Error time output mode" is set to "Hold"

(a) Since the communication with the DP-Slave is continued, values at the time of the CPU

module stop error occurrence are held as the output data sent to the DP-Slave from the

QJ71PB92V.

(b) Input data received from DP-Slaves are updated into the buffer memory of the QJ71PB92V.

(2) When "Error time output mode" is set to "Clear"

(a) Communications with DP-Slaves are interrupted, and output data are not sent.

(b) Input data received from DP-Slaves are held in the buffer memory of the QJ71PB92V.

When the QJ71PB92V is mounted in a redundant system, set the watchdog timer for DP-Slaves so

that the calculation formula shown in Section 4.8 (5) is satisfied.

If the formula is not satisfied, a watchdog timer error occurs in DP-Slaves during system switching.

CAUTION

Do not install PROFIBUS cables together with the main circuit or power lines or bring them close to

each other.

Keep a distance of 100mm (3.94 inches) or more between them.

Failure to do so may result in malfunction due to noise.

A- 3

[Installation Precautions]

CAUTION

Use the programmable controller in an environment that meets the general specifications in the

user's manual for the CPU module used.

Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the

product.

To mount the module, while pressing the module mounting lever located in the lower part of the

module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the

module until it snaps into place.

Incorrect mounting may cause malfunction, failure or drop of the module.

When using the programmable controller in an environment of frequent vibrations, fix the module

with a screw.

Tighten the screw within the specified torque range.

Undertightening can cause drop of the screw, short circuit or malfunction.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Shut off the external power supply (all phases) used in the system before mounting or removing the

module.

Failure to do so may result in damage to the product.

Do not directly touch any conductive parts and electronic components of the module.

Doing so can cause malfunction or failure of the module.

A- 4

[Wiring Precautions]

WARNING

Be sure to shut off all phases of the external power supply used by the system before wiring

PROFIBUS cables.

Failure to do so may cause the module to fail or malfunction.

CAUTION

Prevent foreign matter such as dust or wire chips from entering the module.

Such foreign matter can cause a fire, failure, or malfunction.

Be sure to place the PROFIBUS cables in a duct or clamp them.

If not, dangling cable may swing or inadvertently be pulled, resulting in damage to the module or

cables or malfunction due to poor contact.

When disconnecting the PROFIBUS cable, do not pull it by holding the cable part.

Be sure to hold its connector which is plugged into the module.

Pulling the cable with it connected to the module may damage the module and/or cable, or cause

malfunctions due to poor contact of the cable.

A protective film is attached to the top of the module to prevent foreign matter, such as wire chips,

from entering the module during wiring.

Do not remove the film during wiring.

Remove it for heat dissipation before system operation.

A- 5

[Startup and Maintenance Precautions]

[Disposal Precautions]

WARNING

Shut off the external power supply (all phases) used in the system before cleaning the module or

retightening the connector screws or module fixing screws.

Failure to do so may result in electric shock or cause the module to fail or malfunction.

Undertightening can cause drop of the screw, short circuit or malfunction.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

CAUTION

Do not disassemble or modify the modules.

Doing so may cause failure, malfunction, injury, or a fire.

Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone

System) more than 25cm (9.85 inches) away in all directions from the programmable controller.

Failure to do so may cause malfunction.

Shut off the external power supply (all phases) used in the system before mounting or removing the

module.

Failure to do so may cause the module to fail or malfunction.

After the first use of the product, do not mount/remove the module to/from the base unit more than

50 times (IEC 61131-2 compliant).

Exceeding the limit may cause malfunction.

Before handling the module, touch a grounded metal object to discharge the static electricity from the

human body.

Failure to do so may cause the module to fail or malfunction.

CAUTION

When disposing of this product, treat is as an industrial waste.
