Abstract

An industrial control system includes an industrial controller and a programming interface. The programming interface is operable to communicate a plurality of operations for modifying a control program maintained by the industrial controller followed by a commit transaction command. The industrial controller is configured to designate the plurality of operations with a pending status and preprocess the plurality of operations. The industrial controller is further configured to commit the operations and clear the pending status responsive to receiving the commit transaction command.
