I have created a tag in PLC (Output tag) it is not connected to any out put terminal. I am trying to browse this tag in SCADA but it is not populating? I am not able to see the created PLC tag.
Share more. PLC model, firmware (if Logix), driver you are using, OPC Item Path you have, et cetera.
Make sure your PLC is in run mode, not program mode. That gets me quite often until I notice it.
