Abstract:
PROBLEM TO BE SOLVED: To provide a switchboard controller that includes a duplex network provided with a control network and a standby network, and is able to examine whether the standby network can normally operate in the state where the control network is normally operating.SOLUTION: A switchboard controller 100 includes: a first CPU 2 set as a control network by a system switching unit 1; and a second CPU 2A set as a standby network. On the basis of an operation signal including address information on the first CPU 2A, a protection relay 20 of a switchboard corresponding to the address creates a state signal of a facility apparatus 26, and the first CPU 2 receiving the state signal outputs a calculation result to an external device. The second CPU 2A receives and stores the state signal.SELECTED DRAWING: Figure 1
