Hello, I have a I/O MOXA device connect to Ignition (V 8.0.15). I have created 3 tags:
-OPC Tag “Is connected” (goes false when the device is disconnected)
-Expression Tag “low temperature” (goes true when analog input goes below a threshold)
-Expression Tag “MOXA Alarm” (goes true when !{[.]Is Connected} || {[.]low temperature}) with configured Notification alarm.
Now, if “MOXA Alarm” change state for “low temperature” start the notification but if change state for “Is connected” doesn’t start.
I tried to remove {[.]low temperature} from “MOXA Alarm” and works but with total expression !{[.]Is Connected} || {[.]low temperature} doesn’t work.
How is it possible?
