You can specify the acceptable time period for a WITS Field Device to respond to a callback request from the Geo SCADA Expert server.
You would issue a callback request to check that a Field Device can dial into the Geo SCADA Expert server (see Callback for WITS Network Connections)). Typically, you would do this for Field Devices that are not scheduled to regularly dial into Geo SCADA Expert (see Scheduled PSTN Dial In for a WITS Outstation) and see Scheduled Network Connections for a WITS Outstation).
When you issue a callback request, Geo SCADA Expert dials out to the Field Device and requests a callback. If the Geo SCADA Expert server does not receive a callback within the time period that you specify, Geo SCADA Expert raises an alarm.
To specify the acceptable time period for a Field Device to respond to a callback request, first select the WITS section in the Global Parameters branch in the Geo SCADA Expert Server Configuration Tool. Use the From and To fields within the Callback section to specify the period (see Working with the Geo SCADA Expert Server Configuration Tool).
