PROBLEM TO BE SOLVED: To efficiently change an operation program by providing a slave station operation program data change means which can change the operation program of a slave station device from a master station device when the master station device and the slave station device are in a normal operation state. SOLUTION: A master station device 101 outputs a slave station program change request based on the PC operation of an operator. When a slave station device 115 receives the slave station program change request from the master station device 101, it is shifted to a data reception operation. Since a means for changing the operation program without stopping the control operation of the slave station device 115 is provided, the content of ROM 212 incorporated with the operation program of the slave station device 115 can easily be changed from the master station device 101 without stopping the operation of the master station device 101 and the slave station device 115. Even if a worker does not need to go to the installation place of the slave station device, the operation program of the slave station device 115 can be changed from the master station device 101. |
