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. To maintain the safety against unauthorized access via the Internet, take measures such as installing a firewall.

To maintain the safety of the programmable controller system against unauthorized access from external devices via the network, take appropriate measures. Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage. Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury. The operation failure may cause the injury or machine damage.

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 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. 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. 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. Please save this manual to make it accessible when required and always forward it to the end user. Always follow the precautions of both levels because they are important for personal safety.

Note that the CAUTION level may lead to serious consequences according to the circumstances. In this manual, the safety precautions are ranked as ' WARNING' and ' CAUTION'. For the safety precautions of the programmable controller system, refer to the User's Manual for the CPU module. The precautions given in this manual are concerned with this product.
