I am installing software redundant, after downloading i got this problem:
1. Both CPU in stop mode:
- at first IM153-2 SF blink, ACT off.
- at second IM153-2 every thing is OK, ACT on
- SF and BF LED at both CPU are off
2. Switch CPU to RUN mode:
- SF LED on at both CPU
- at first IM153-2 SF blink, ACT off.
- at second IM153-2 every thing is OK, ACT on
Could anybody tell me what is wrong? i attach my hw config and network picture along with my program. DiagnoseA.txt and DiagnoseB.txt are the event i recorded from diagnose buffer of CPU A and CPU B respectively.
