AUTOMATED INPUT SIMULATION FOR SIMULATED PROGRAMMABLE LOGIC CONTROLLER

摘要

Input simulation is provided (36) as part of simulating (38) a programmable logic controller. The simulator program itself includes a graphic user interface for the user to configure a sequence of changes in input values. For example, the value of a variable is to be changed at each of multiple times. The sequence is used to simulate (38) the PLC reaction to the changing input in real-time. The output is provided (40) in real-time.
