PROBLEM TO BE SOLVED: To efficiently execute the debug test of a processing program to be executed by each PLC(personal computer) without using any actual equipment in a job site in an FA(factory automation) system in which plural PLC are connected with a line. SOLUTION: A first transmission path emulator means 13 or a second transmission path emulator means 14 receives transmission data from a virtual PLC virtual communication unit means 111, and transmits the received transmission data to virtual communication unit means 121 of #1-#n virtual PLC 12 after the delay of a prescribed time. Also, the first transmission path emulator means 13 or the second transmission path emulator means 14 cheeks the overlap of a registered network address by referring to a node allocation table 17 at the time of registering the network address of a communication equipment constituting a communication system. |
