Modbus Address Mapping error

I deleted a row of modbus tag addresses because they were incorrectly named. This caused all the tag values in the same device to go bad quality. I tried to add them back to undo it but it made no difference. An suggestions on why this happened or how to solve it. Does the tag path to the device change for the other addresses when a row is deleted?

Thanks

No.

Are you sure you added them back exactly as before?

Tip: Don't use the Modbus Address mapping configuration. Just manually address the OPC tags as described in the manual (for manual addressing). Then these kinds of mistakes are not possible.
