2) LED indication description
(1) RUN: indicate that communication with PLC CPU is normal.
- On: interface with PLC is normal.
- Off: interface error or interface stop.
Since flicker period changes according to PLC scan, when PLC scan is long (more than
200ms) or PLC has more than two communication module and exchange a lot of data, LED is
on every 1, 2 second, so the user may consider that LED is off. But this is because data
calculation is getting slow because of many data and this is not abnormal operation of
communication module.
