Parameters > Citect.ini File Parameters > Dial Parameters > [Dial]WatchTime


The period at which the I/O Server checks for I/O devices to contact and checks for incoming calls from dialling I/O devices. The WatchTime should be less than your modem's inactivity timeout (if you are using dial back), otherwise the modem will hang up and CitectSCADA will miss the call.

Allowable Values: 1 to 600 (seconds)

Default Value: 20
