Associated with: Direct and Shared outstations for which the direct connection is available on demand rather than always online

Security permission required to access this pick action: Retrieve Data

WARNING

UNEXPECTED BEHAVIOR OF APPLICATION

Use the Close Connection pick action with care. Always check an outstation’s current activity before deciding whether to use this action.

To check whether an outstation is currently processing a request, look at its entry in the Outstation List’s Current Request column. You can also check an outstation’s current activity via, for example, the Events List or the outstation’s Status display.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

This pick action is only available while the direct connection to an On Demand outstation is open (that is, while ClearSCADA is in the process of retrieving data from, or sending controls to, the outstation).

If necessary, use the Close Connection pick action to close the direct connection that is currently open.

When the Close Connection pick action is executed, ClearSCADA completes any outstanding read response, then closes the connection. Any actions that are otherwise in progress, or are outstanding, are canceled.
