Pulling in a tag from a PLC5. Tag in the browser has a question mark and the value is Null. Its a float (F8:5), non zero value.

Thanks!

Just a follow up. I could not figure out what the issue was and didn't get any help here. Using quick client, the tag values were good, just the tag browser they were showing 'null'.

I rebooted the Ignition server VM. The tags are working correctly now.

Do you know what was the status of the device in Ignition?

One issue, with SLC driver, is that the device connection is stuck at the status "Disconnected: browse pending", and do not reconnect. I don't know the cause, but I have a scheduled script that disable, then re-enable the device, when the status match.
