Meaning
This register stores error detection status in the following bit
pattern.

Empty
1): When Xn0 of a mounted CC-Link module turns on, the
corresponding bit is set to 1 (on).
2): When either Xn1 or XnF of a mounted CC-Link module turns
off, the corresponding bit is set to 1 (on).
3): When a mounted CC-Link module is not able to
communicate with the CPU module, the corresponding bit is
set to 1 (on).
The above modules are numbered in order of the head I/O
numbers. (However, the one where parameter setting has not
been made is not counted.)
