IAC timeout alarm
We will be getting alarm (System alarm) for IAC time out? or it will be only system event? Could any one please confirm this.
In one our project we are using IAC between applications within a controller.
In this case how to generate the IAC time out or IAC failure to demonstrate to the customer? Customer want to have alarm upon IAC failure/time out.

You can try using a variable of datatype HwStatus and connect it to the IAC MMS Unit Status (Under IP) in the Controller Hardware. This datatype has the ErrorsandWarnings which will contain the information if there is a connection failure. For example if the variable connected to UnitStatus is vIACError, you will get the information in vIACError.ErrorsAndWarnings.B0
Hi,
In the communication variables tab there is a option called Status for each declared variable.
In Online,this status value will change based on the communication status.
Use this value and try to make an alarm.
Simply disconnect the ethernet cable between controllers to make the timeout.
