Safety and/or reliability may he improved in industrial control systems by optimally utilizing integrated circuit elements to reduce the amount of components required and to provide cross monitoring. In one aspect, circuitry that is part of an Integrated Circuit (IC) for controlling a first channel may also be used to monitor and provide safe operation for circuitry for controlling a second channel, and the circuitry for controlling the second channel may similarly be used to monitor and provide safe operation for the circuitry controlling the first channel. Circuitry may include a windowed watchdog circuit which may be used to monitor various events of the other circuitry, and safe operation may be provided by removing power from the other circuitry to provide a safe state.
