1 GX Developer Version 8 Operating Manual (Safety Programmable Controller)-SW8D5C-GPPW-E A - 1 A - 1 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. In this Manual , the safety precautions are classified into two levels: "WARNING" and "CAUTION".

2 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 Instructions] ! WARNING When data/program change, or status control is performed from a PC to a running safety programmable controller, create an interlock circuit outside the sequence program and safety programmable controller to ensure that the whole system always operates safely.

3 For the operations to a safety programmable controller, pay full attention to safety by reading the relevant manuals carefully, and establishing the Operating procedure. Furthermore, for the online operations performed from a PC to a safety CPU module, the corrective actions of the whole system should be predetermined in case that a communication error occurs due to a cable connection fault, etc. When a safety remote I/O module has detected a CC-Link Safety error, it turns off all the outputs. Note that the outputs in a ladder program are not automatically turned off.

4 If a CC-Link Safety error has been detected, create a ladder program that turns off the outputs in the program. If the CC-Link Safety is restored with the outputs on, it may suddenly operate and result in an accident. To inhibit restart without Manual operation after safety function was performed and outputs were turned OFF, create an interlock program which uses a reset button for restart. A - 2 A - 2 [Startup/Maintenance Instructions] !

5 CAUTION The online operations performed from a PC to a running safety programmable controller (Program change when a safety CPU is RUN, device test, and Operating status change between RUN and STOP) have to be executed after the Manual has been carefully read and the safety has been ensured. Following the Operating procedure predetermined at designing, the operation has to be performed by an instructed person. When changing a program while a safety CPU is RUN (Write during RUN), it may cause a program breakdown in some Operating conditions.
