Abstract
A software logic controller using flowchart programming includes exception handling elements for handling exception conditions in a manufacturing process. Exception handling is programmed using a Begin Exception element to start monitoring the occurrence of a specific exception condition and an End Exception element to stop the monitoring process. Monitoring is conducted once during every scan cycle of the computer as long as the Begin Exception element is still active.
