PURPOSE:To attain the simulation of the whole plant without adding/changing software of a process control device in working by changing corresponding relation between a data transmission equipment and its connecting equipment. CONSTITUTION:A signal to be transmitted through a process I/O device 10, an address converter 6, a common memory address A in a data transmission equipment 2, a common memory address A in a data transmission equipment 4, a common memory address A in a data transmission equipment 3 and a programmable controller 11 successively at the time of normal control is transmitted through the process I/O device 10, the address converter 6, a common memory address B in the equipment 2, a common memory address B in the equipment 4, a plant simulator device 13, the common memory address A of the device 4, the common memory address in the equipment 3, and the programmable controller 11 successively at the time of simulation. Consequently, the simulation of the plant can be attained without changing the program of the programmable controller 11. |
