When I connected a new PLC and create some new OPC tags, I found all of these tags are with green question marks.
What should I do? Restart gateway or module?
Ignition 7.9.17
Ignition 7.9.17
Try restarting just the device. (Edit the device and save without actually changing anything.)
Thank you, Phil.
I tried, but not work.
Electrician told me that PLC firmware is above V21. So I deleted the device then create it again use the new firmware version.(Before that I used legacy version)
Working now.
Thanks again.
I didn't understand your solution. Deleted the device from Ignition?
Where does the firmware factor in to it (i.e. where is it specified in the PLC configuration under Ignition devices)?
It's not a setting, but a different driver for ControlLogix V20 and older, and CompactLogix V20 and older, versus generic Logix V21+. (With a caveat for v20.19. Details in the docs.)
