Server Redundacy for system 800xA version6.0.3
Hello, dear collègue.
I work for ABB Malaysia, and I have the next problem:
I have two server using window 10 IOT enterprise software for the system 800xa version 6.0.3. i have observe that, both server service are running well but checking the rnrp for ASCS1 its show primary port of ASCS2 and PM864 (controller) is down but can be ping from ASCS1. refer ASCS1 attachement .
Same goes for ASCS2 server the rnrp show ASCS1 primary is down. refer to attachement ASCS2.
Please could you help me on this project?
Don't trust ping when RNRP service is running. One of the main purposes with RNRP is to automatically adjust the routing table to counter a network disconnection/break. Ping will not know/tell if the telegrams are exchanged via the secondary network.
Stop the RNRP Service (in Windows Control Panel>Administrative Tools>Services) if you want to "see the truth" with ping.
I suggest that you examine the network hardware used for primary network.
If ping work OK even with RNRP service stopped, the problem is likely that you have IGMP enabled on the primary network. RNRP requires that IGMP is disabled.
