Ignition cannot detect changes in PLC values

Hi Everyone,
Calling all experts! I'm currently designing screens using Ignition 8.3.3 and running into an issue where Ignition fails to detect the signal reset from a Siemens S7-1500 PLC.

Here is the specific scenario: Ignition directly collects alarm signals from the S7-1500. When a PLC alarm is triggered, the screen element flashes to indicate the alarm, and it should stop flashing once the alarm is reset.

However, I'm facing an intermittent issue where the Ignition screen keeps flashing even after the PLC alarm value has been reset.

What could be causing this? How can I resolve it?

You should show us the tag configuration, the binding and the system you are using to display the plc alarm value, then we might be able to help.





Hi!
You can check the photos of the tag configurations. In actual operation, the values of some PLC tags occasionally update while the corresponding tags collected by Ignition stay unchanged. This can only be fixed by restarting the OPC connection for now. Let me know if you need any further information. Thank you.

Please show us the binding on the perspective view.
Could happend that everything is working but the binding is not set correctly and therefore is not updating correctly.

How is your default tag group defined?

What scripts do you have on your tag?

There are no alarms on your tags, so do you just mean values aren't changing?
