Last Polled

Associated with: Outstations, including Slave outstations

This status attribute displays the date and time that the server last polled (scanned) the outstation.

(With a Slave outstation, this is the last time that the Slave’s SCADA master scanned the Slave (the ClearSCADA server) for data. The SCADA master might be another ClearSCADA server or a third-party server.)

For new outstations that have not yet gone ‘live’, the Last Polled attribute displays the value ‘Never’.
