Disable Channel

Associated with: Channels

Security permission required to access this pick action: Disable Points

NOTE: The 'Disable...' series of pick actions are assigned the 'Disable Points' security permission so that users with that permission can disable database items without necessarily being given the full 'Configuration' security permission. A user, such as an operator, whose User Account is given the 'Disable Points' permission but not the 'Configure' permission can disable a database item, but is prevented from altering the rest of that item's configuration.

Use this pick action to take a channel Out of Service.

The Disable Channel pick action clears the channel's In Service property, so that the channel is no longer active.

You might want to disable a channel, for example, if ClearSCADA has detected a problem with that channel. Once the problem has been rectified, use the Enable Channel pick action to place the channel back In Service.

ClearSCADA logs an entry in the Event Journal whenever either pick action is used. The entry indicates whether the channel has been enabled or disabled.

If the channel is the sole means by which ClearSCADA communicates with certain devices, disabling the channel will also de-activate those devices and their dependants, although their configuration will remain unchanged.

If using this pick action with the Automation Interface, you need to specify the method name Disable.
