SAFETY PRECAUTIONS
(Always read these instructions before using this product.)
Before using this product, thoroughly read this manual and the relevant manuals introduced in this manual 
and pay careful attention to safety and handle the products properly.
The precautions given in this manual are concerned with this product. For the safety precautions of the 
programmable controller system, refer to the User’s Manual for the CPU module.
In this manual, the safety precautions are ranked as "
 WARNING" and "
 CAUTION".
Note that the 
 CAUTION level may lead to serious consequences according to the circumstances.
Always follow the precautions of both levels because they are important for personal safety.
Please save this manual to make it accessible when required and always forward it to the end user.
[Design Instructions]
[Startup and Maintenance Instructions]
 WARNING
● When data change, program change, or status control is performed from a personal computer to a running 
programmable controller, create an interlock circuit outside the programmable controller to ensure that the whole 
system always operates safely.
Furthermore, for the online operations performed from a personal computer to a programmable controller CPU, the 
corrective actions against a communication error due to such as a cable connection fault should be predetermined as 
a system.
 CAUTION
● The online operations performed from a personal computer to a running programmable controller CPU (Program 
change when a programmable controller CPU is RUN, operating status changes such as forced input/output 
operation and RUN-STOP switching, and remote control operation) must be executed after the manual has been 
carefully read and the safety has been ensured.
When changing a program while a programmable controller CPU is RUN, it may cause a program corruption in some 
operating conditions. Fully understand the precautions described in GX Works2 Version 1 Operating Manual 
(Common) before use.
● The positioning test functions of OPR, JOG, inching or positioning data for QD75/LD75 positioning module must be 
executed with the programmable controller set to STOP after the manual has been carefully read and the safety has 
been ensured. Specially when executing the function on the network system, ensure the safety thoroughly since the 
machinery whose operation cannot be checked by an operator may be activated. The operation failure may cause the 
injury or machine damage.
