FACTORY talk view SE tag change event

Post by sshah » Fri Aug 21, 2020 5:14 pm

Hello Guys.
Need a desperate help

I am trying to get a message being displayed in local message box in factorytalk view SE up on the change in tag value from 0 to 1 in PLC. Tag is in PLC whose value i need to keep checking and up on it's change from 0 to 1 and 1 to 0 i need to display message accordingly.

I need to use VBA as i can not touch plc problem.

I have used a lot of examples from help but can not get the tag change event triggered in vba code.
Please somebody help with the code.

Remember i have to use VBA and nothing else.
So VBA should be able to see tag change in. PLC and then on display message should be displayed on local message display.
