Associated with: PSTN outstations or outstations with PSTN fallback; Slave PSTN outstations
This pick action is only available on an outstation:
- That supports call extensions
- For which your User Account is allocated the Retrieve Data security permission.
Use the Extend Line pick action to reset a PSTN call that is in progress, if that call is otherwise likely to terminate before ClearSCADA has finished retrieving the outstation’s data. ClearSCADA re-applies the outstation’s Maximum Call Length from the instant that the Extend Line action is executed. For more information, see Define an Outstation’s PSTN Properties in the ClearSCADA Guide to Advanced Drivers.
