CONSTITUTION:Control stations A1, A2,...An are provided with the same function, and a common control station B exercises general control over control stations A1, A2,... An. Here, interfaces 1-4 for confirming operation status are provided which links every control in a chain configuration. Further, a data bus 5 is provided for exchanging data between the common control section B and control sections A1, A2,..., An. Thereby each control section confirms mutually the operation status through the interfaces 1-4 of other section. |
