SIMULATION OF PROGRAMMABLE LOGIC CONTROLLER INPUTS AND OUTPUTS

摘要

The disclosed embodiments relate to simulation of one or more PLCs 302 which are to be physically implemented on conjunction with other devices 304 306, such as sensors or other devices 304 which provide information or signals to the PLC and/or actuators or other devices 306 which are controlled or otherwise receive information or signals from the PLC 302, e.g. to monitor and/or control various industrial machines or processes. The characteristics, physical or other attributes, of the interconnection(s) 308 between the PLC 302 and the other devices 304 306 are modeled 116 118 120 and simulated to ensure that the PLC 302 behaves in a manner consistent with the characteristics of the interconnection 308. Accordingly, using the disclosed embodiments, simulation of a PLC 302 will provide a more accurate representation of the expected actual operation thereof in the actual environment
