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.
This doesn't affect the subscribing of the tag in ignition though, you can still browse and read the tags when the plc is in program mode
I said that incorrectly. At least for Rockwell Logix, if you haven't yet downloaded the program with your new tag and put the PLC into run mode, you won't see it yet. If you work mostly in offline mode like me at least.
Thank you for responding everyone. I am able to see the tag in SCADA. However it shows local tags that I created (Scope- Main program) I create global tag with controller scope and it wasn't showing it in SCADA but when I tried local tags it was available under main program folder.
I don't know the reason why it let lcoal tag visible and not global. I will check on this.
Check for "ExternalAccess: None". That will prevent external systems from seeing that tag.
Sure, I will look for this.
