OPC HDA Failover

Question asked by AnshulSo29 on Nov 18, 2020



We have 2 OPC HDA server which are currently working as data source. We have only 1 interface and we want to configure failover in case any one of my source is down due to any issue.


We added the secondary server in Backup server details and tried testing by taking out primary server from network but it is not working and the interface is not switching between the backup & primary server for data.


Is there anything that we are missing out in configuration or someone can help in the same?
