A case is shown in which the control target R3 of the process equipment connected to the remote station device 4-n from the cut-off switch 8 is turned on/off. The control signal issued from the switch 8 is transmitted to the slave station device 4-1-=line 6-/master station device 2-/LAN 5
- Transmitted to the transmission relay exchange device 7, relayed and exchanged there, and transferred to the transmission relay exchange device (Go47-・1., AN 5
-> Master station device 3 - line 6 - and slave station device 4-n, and control the on/off of the control target R of the process equipment. On the other hand, when the switch 8 is located far away and cannot be operated, when operating the switch of the supervisory control device L to turn on/off the controlled object R, , the control signal emitted from the supervisory control device I is transmitted to the relay exchange device 7.
