PROBLEM TO BE SOLVED: To reduce the number of wirings among equipments and the number of components, to compact respective equipments and to improve a control function in the case of executing sequence control for a power converter by using a sequence controller. SOLUTION: A controlling microprocessor 6 is directly connected to a sequence mictoprocessor 11 through a bus 20 to save wirings and terminals. A personal computer 13 is connected to a sequence controller 10 through a serial communication function 12 and detachable I/O devices 21, 22 are attached to the controller 10 to omit a touch panel. A storage device 23 is also attached to the controller 10. Consequently the whole device can be compacted, the number of components can be reduced and the control function can be improved. |
