Communications with safety stations
This function establishes a safety connection and performs one-on-one safety communications periodically between safety
stations in the same network.
Safety data is exchanged by using the safety device of the Safety CPU set by "Safety Communication Setting" under "Basic
Settings" from a program.
Whether a safety connection is established or not can be checked in 'Safety refresh communication status of each safety
connection (1st module)' (SA\SD1008 to SA\SD1015) of the Safety CPU.
