I have a datatype in my PLC that uses the suffix "\_Hist" to denote a historical value.

At first this PLC tag was initially created with the suffix "\_HIST" instead of "\_Hist". However, after changing it in the PLC the OPC server on ignition still shows the "\_HIST" suffix.

How can I resolve this?

Have you restarted the device? And refreshed the OPC browser? Tag names in Logix processors are case-insensitive case-preserving, so it might not have registered as a change.

I was able to fix it by renaming online. Renamed first to "\_h" then checked the browser to see the change take affect. Then change to "\_Hist". All good now.

The old-case tag must've still existed in RAM so renaming with only a case change must've grabbed that old name. I've seen that before with Logix processors when trying to create tags like that.

Thanks
