The DNP3 protocol provides Frozen Counters that allow a DNP3 master (Geo SCADA Expert) to request the outstation to create a frozen ‘snapshot’ of the values of its counters.
Use the fields within the Freeze section of the DNP3 tab to specify whether the outstation supports frozen counters, and whether Geo SCADA Expert requires a response to freeze counter requests.
Select this check box if the outstation supports DNP3 frozen counters, and you intend to send DNP3 freeze counter controls to the outstation.
Clear the check box if the outstation does not support DNP3 frozen counters, or you do not intend to issue DNP3 freeze counter controls to the outstation.
Select this check box for Geo SCADA Expert to request a response to any DNP3 Freeze Counter requests that it issues to the outstation.
Clear the check box if responses are not required.
