CONTROL SYSTEM WITH ERROR DETECTION

A control system for controlling a process. The control system includes primary and secondary module buses over which information may be transmitted between a controller and a plurality of I/O modules. Each of the controller and I/O modules has a power sense circuit for detecting current on the high...

Zusammenfassung:	A control system for controlling a process. The control system includes primary and secondary module buses over which information may be transmitted between a controller and a plurality of I/O modules. Each of the controller and I/O modules has a power sense circuit for detecting current on the high side of a driver and a ground sense circuit for detecting current on the low side of the driver. The driver is determined to have failed if either the current on the high side of the driver measured by the power sense circuit is outside a predetermined high range or the current on the low side of the driver measured by the ground sense circuit is outside a predetermined low range.
