Abstract:
1. A control system device, comprising: a multiple channel discrete output module, said module storing a plurality of fail-state parameters, each fail-state parameter from the plurality of fail-state parameters corresponding to one channel of the multiple channel output module, said module adapted to be communicatively coupled to a programmable logic controller (PLC), the PLC adapted to detect a fault condition, the PLC adapted to check for an error handler responsive to the detected fault condition, the error handler adapted to attempt a recovery from the fault condition without halting execution of a program by the PLC, the PLC adapted to enter a stop state if the error handler does not provide the recovery from the fault condition, the module adapted to receive a command from the PLC responsive to the stop state, the command adapted to cause at least one fail-state parameter of the plurality of fail state parameters to be provided to a channel of said module; and a plurality of indicators, each indicator corresponding to a single channel, each indicator adapted to communicate a short-circuit status of its corresponding channel to a control system coupled to said control system device, said multiple channel output module adapted to detect an error in a signal on at least one channel of said multiple channel output module, said multiple channel output module adapted to correct the error in the signal.
