(OPCActivate label 0|1)
The name for this connection, as displayed in the OPC option of the Properties window. If label is * then the command affects all currently configured connections.
If 1, the group is activated; if 0, it is deactivated.
This command activates or deactivates the OPC group in the OPC server representing the connection specified by label. This sends a message to the OPC server to activate or deactivate the underlying group. The result of deactivating a group is that subsequent read and write attempts will fail until the group is activated again.
