• The communication status of safety stations connected to the 5th 
CC-Link IE Field Network module (the one whose start I/O number is 
stored in SD1908) is stored.
• A communication error means that the safety station is not in any of 
the communication states stored in SA\SD1104 to SA\SD1223.
The bit arrangement of the safety connection number is the same as 
that of the 1st module. (Note that the SA\SD numbers differ.)
