DriverMUX Tag Type Properties: Settings Tab

In the event of a communication failure, the DriverMUX tag will poll the failed driver at a decreasing frequency, watching for communication to be restored.  This is done to allow communication to be re-established as quickly as possible in the event of a momentary outage, but to also reduce network load devoted to polling in the event of a longer outage.

Min Test Time(seconds)

The initial frequency at which checks are made to determine a failed driver's state.

Max Text Time (seconds)

The longest period to wait between checks of a failed driver.

Backoff Rate

The time between tests is multiplied by this rate to obtain a progressively slowing frequency between tests until the Max Test time is reached.

Secondary Ping Time (seconds)

When the mode is set to Primary Preferred and the primary driver is in use, the secondary driver is tested at this rate to ensure its availability.
