Immediate response when interrupted connection is detected
Can only be enabled if the "Maintain connection permanently" option is selected. The immediate reporting of S7 connections that have not been established with OPC jobs, means that you avoid repeated job timeouts.
Functional description: An interrupted connection is detected and the connection stored. If the connection has not yet been established or it is currently being attempted to re-establish an uninterrupted connection, OPC jobs are replied to immediately with an error message to this effect. The error message is sent without waiting for the job or connection timeout.
