Deltav Controller IP Addr Discrepancies

The DeltaV network is configured in two subnets 10.4.x.x for Primary and 10.8.x.x for Secondary. The Primary controller's IP address is 10.4.0.86 and the Secondary controller's Ip address is 10.8.0.86. When switching over redundancy controllers, the addresses displayed on diagnostics is 10.4.0.86 and 10.5.0.86.

Communications to operator stations are not affected so is this IP addr discrepancies a concern?

Why is the secondary controller showing a different address than what is configured?

Thanks

  • The primary controller uses 10.4.x.x and 10.8.x.x. The redundant controller uses 10.5.x.x and 10.9.x.x. This is expected behavior. As a reminder, DeltaV sets the IP addressing for each node and it should never be changed manually.
