Syntax

disconnect(obj)

Description

disconnect(obj) disconnects the OPC client object obj from the server. obj can be an array of objects.

If the disconnection from the server was successful, the function sets the Obj property Status value to 'disconnected'. You can reconnect obj to the server with the connect function.

If obj is an array of objects and the function cannot disconnect some of the objects from the server, it disconnects the remaining objects in the array and issues a warning. If the function can disconnect none of the objects from their server, it generates an error.
