Communications Failure During Store

The Fault Group Communications Failure During Store occurs during the store of program blocks and other data to the PLC. The stream of commands and data for storing program blocks and data starts with a special start-of-sequence command and terminates with an end-of-sequence command. If communications with the programming device performing the store is interrupted or any other failure occurs which terminates the load, this fault is logged. As long as this fault is present in the system, the controller will not transition to RUN mode.

This fault is not automatically cleared on power-up; the user must specifically order the condition to be cleared. The fault action for this group is Fatal.

Correction: Clear the fault and retry the download of the program or configuration file.
