In RTU Panel we are having several Analogue & Digital
Inputs /Outputs. We are recently facing some problems over
Analog inputs , which are not updating properly (But
Digital Input are updating normally) Can any one tell me
from where the problem is creating , we have checked PLC
CPU card, Analog Input card & we reconfigured ,But still
the issue is there.
Issue :
1. Sometimes Analog values are updating & sometimes not.
2. Analog values are not updating normally , showing some
wrong Values
3. Total dead (0 value)
Analog values are Level & flow measurement from the field
instruments.
(But in field the instruments are working normally &
Displaying the values normally in local display unit)
This problem we are facing in our Water Plant.
If any one experienced this same problem or having any
ideas related to our issue PLS send your valuable
