I have an existing PLC program. I have a tag provider correctly connecting all tags with this plc program. I went ahead and added a new tag in the PLC program. I went to add the tag within Ignition and I couldn’t find it by browsing for it however I am able to see every other tag in the plc program that was previously there. I also went ahead and added the tag path manually and it is still telling me there is an error.
Any ideas?
Hey @michael.black I have had this happen to me before. try disabling the PLC OPC client connection in the gateway and reconnect it. That worked every time for me. for some reason sometime the new tags are not being pulled in.
hope this helps.
You don’t need to disable, just open and save it to restart it and force it to rebrowse. Or I guess if you want to script it, then you would have to disable and enable
Thanks guys. I tried eveyrthing. I finally ended up just restarting the VM that I had ignition running on and the new tags showed up.
Thank you for asking this question and Mr.K001's response.
I had the same problem....couldn't get a Control Logix PLC tag to show up no matter what....went to the Gateway, disabled the device and enabled the device......tag showed up.
Yes, I hit refresh numerous times, exited Ignition, saved the PLC program, waited etc. etc.....unchecking the enable box, saving and then enabling, saving in the Gateway was what worked.
See also the "Automatic Rebrowse" setting in your device's advanced connection settings.
Understand....I swear that the automatic rebrowse was checked (believe it's the default) in the advanced settings of the device/PLC......believe this has happened before once and the only solution that I found was to disable and then enable the PLC topic in the Gateway. Didn't happen for all tags....but for a few that had similar names that was the only way that I could get it to show up (map in Ignition).
There are some funky situations with some firmware that doesn't update the controller properties that signify a change. So, sometimes a rebrowse needs to be forced. (You don't actually have to disable, save, enable, save. You can just open the device's edit page and save.) There are script functions, too.
Okay....I'll try going to the Gateway PLC device and saving.....at least I know how to fix the issue
