Activates all mappings within a pipe. When a pipe is activated, the destination item in the mapping is updated when the source item for that mapping changes.
You can set the initial pipe active status in Mirror Configuration.
If you are running redundant OPC Mirror clients on a pair of Application Stations, Mirror Diagnostics functions independently on each Application Station. Therefore, for example, assuming a pipe that is deactivated on both Application Stations where the active and standby OPC Mirror clients are running, if you activate it on one Application Station, it is not automatically reactivated on the other Application Station. The pipe will continue to remain deactivated until you explicitly activate it.
