Abstract: PURPOSE:To enable a test despite fault of an interface and to perform effectively the test of a control function, by multiplexing the input/output parts of a slave station device and a sequencer and obtaining coincidence among test switch modes to avoid an erroneous control. CONSTITUTION:In a normal state a test switch command given from a master station device is delivered to a sequencer from a coding signal connecting circuit 39. The contents of a test switch command storage circuit 12 are changed via an OR gate 64 through an input/output part 9I, for example, connected to a using system. The contents of the circuit 12 are changed also for an input/output part which is not connected to the using system. While in case the interface of the circuit 39, etc. has a fault, a fault signal 70I is delivered to an AND gate 60. In this case, if own sequencer 40I belongs to the using system, a signal 71 given from an input circuit 14 is applied to the gate 60. Then a logical signal is sent to an AND gate 63 from the gate 60 to enable the test.
