Abstract
The present disclosure describes embodiments of a control system and a switch simulation device for use in the control system. The switch simulation device provides diagnostic capabilities that verify the accuracy and operability of sequence of events (SOE) data and SOE detection functions of the process control system. In one embodiment, the switch simulation device includes a pair of switches (e.g., metal-oxide field effect transistors (MOSFETS)) that are anti-parallel to one another. A drive circuit operates the switches at a pre-determined frequency to generate an output signal that simulates the position of switches that are coupled to components on the asset. The output signal impresses on contact inputs, which are coupled to the switches, and which are useful to generate the SOE data.
