! !

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

follows. Configure an interlock circuit in the sequence program using the communication status information (input X1) so that the system can operate safely. Failure to do so may result in an accident due to an incorrect output or malfunction. (1) The input data from the master station remains unchanged from the data prior to the

communication error.

(2) When the master station becomes faulty, the output status of the QJ71PB93D will be as in

the parameter settings of the master station.

(3) When any QJ71PB93D is down, the output state of other slave stations will be in

accordance with the parameter settings of the master station.

 Do not output (turn on) the "Use prohibited" signal as the output signal to an intelligent function

module from the CPU module. Writing data into the "system area" or outputting a signal for "Use prohibited" may cause system malfunction in the programmable controller.

A - 1 A - 1

CAUTION

 Do not install the PROFIBUS cables together with the main circuit lines or power cables.

Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

[INSTALLATION PRECAUTIONS]

CAUTION

 Use the programmable controller under the environment specified in the user's manual of 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 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 malfunctions, a failure, or a drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw. Tighten the screws within the range of specified torque. If the screws are loose, it may cause the module to fallout, short circuits, or malfunction. If the screws are tightened too much, it may cause damage to the screw and/or the module, resulting in fallout, short circuits or malfunction.

 When disconnecting the PROFIBUS cable from the module, do not pull by holding the cable

section. To disconnect the cable, make sure to hold the connector which is coupled with the module. Do not attempt to pull the cable to disconnect it from the module. It could damage the module or the cable, or cause malfunction due to a 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.

[STARTING AND MAINTENANCE 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 of 50 times may cause malfunction.

(4) Swapping of I/O data

When I/O data is sent/received from/to the master station, their upper and lower bytes can be swapped. Though PROFIBUS-DP handles the upper and lower bytes of I/O data differently depending on the master station type, the I/O data need not be swapped in a sequence program. (Refer to Section 4.1.4)

(5) Start/stop of refreshing the input send area

Refreshing of send data from the QJ71PB93D to the master station is controllable by an output signal (Y00). Providing an interlock disables the buffer memory data from being sent to the master station at error occurrence. (Refer to Section 4.1.1)

(6) Extended trouble notification function

Data stored in the extended trouble information area of the buffer memory can be sent to the master station as extended trouble information faulty, for example. When the host is not faulty anymore, notify the master station that there is no fault. (Refer to Section 3.4.2(9))
