Hi geys ,
I'v communication problems between REF542 plus and PLC , and the status on HMI indicate IBB Error
I've red LED 'Ibb error' in HMI of ABB Ref 542plus. When I reset the Modbus communication board in the first and the second Ref 542plus the LEDs 'Ibb error' becomes green. In the third Ref 542plus it becomes green a few seconds and becomes red , when i checked the slave ID adress on ref542plus it become 99 fault adress , I reset several times but the LED stay red. When I checked the communication board LEDs:
The first LED (communication board monitoring) blink 0.5 seconds period
in the first and second communication board:
The first LED (communication board monitoring) blink 2 seconds period
help me please !
