4 PRECAUTIONS FOR USE OF SAFETY PROGRAMMABLE CONTROLLER
4.2 Precautions for Programming
Programs to be used in a program for realizing safety functions
Configure input and output data of a program for realizing safety functions using safety data. Determine the safety/non-safety
of input/output data as follows.
■Devices transferring safety data through safety communications with safety remote I/O
module
The safety data of devices transferring safety data to be refreshed by safety communications with the safety remote I/O
module is a safety data.
*1 These are inputs such as an emergency stop switch, safety switch, and light curtain.
*2 These are the outputs such as a power source of robots.
User devices to be refreshed by communications with standard remote I/O module can be used only by standard program.
When using standard remote I/O module inputs and outputs with safety program, use standard/safety shared label to deliver
data between standard and safety programs. ( Page 37 Standard/safety shared label)
■Devices transferring safety data by safety communications between Safety CPUs
The safety data of devices transferring safety data to be refreshed by safety communications between Safety CPUs with the
CC-Link IE Field Network is a safety data. For details, refer to the following.
