Indicators
Note
Depending on the interval of flashing, the meaning is as follows:
Protocol data being initialized: 0.3 s
Protocol data being overwritten: 1.0 s
Protocol data error: 1.0 s and CPU Unit ERR/ALM indicator is flashing
CPU Unit Indicators
A Serial Communications Board is mounted as an Inner Board in the CPU
Unit and thus affect the CPU Unit ERR/ALM indicator.
If an error in the Inner Board is the cause of the error indicated on the ERR/
ALM indicator, information on the error will be stored in A424: Inner Board
