 Post subject: Reading Value from Redundant Controllers

Hi,
I had a project which uses redundant CompactLogix (1769-L33ER).
One Controller acts as primary, this means only the value from primary is going to be displayed in HMI. (FYI, I use Ix Panel TA150).

In case of primary controller fail, the primary status will be transferred to second controller (this is done in PLC). But in HMI, eventhough I can read the status of failure, it is still reading from the first PLC.

I am planning to use Alias, however, it might be inefficient solution because there are 1105 tags that must be duplicated.
Does anyone have better solution? Can I do something with scripting?
Thank you.


Best regards,
Andrew
