Abstract
PURPOSE:To prevent the malfunction, by enabling the operation for a plurality of sets of the remote monitor and control unit as one set, through the provision of the multiplex selection and detection circuit between sets with the master and slave stations. CONSTITUTION:The control desk 13 is connected with the master remote and monitor control units TC 4,5,6 to perform the parallel units 4,5,6 in three sets as one set. The unit selection switch 14 from the control desk 13 performs multiplex selection and detection check every set with the multiplex selection detection circuits 16 to 18, and if the selection is good, the selection excellence signal 23 is outputted to the multiplex selection and detection circuit 22 between sets. Further, the circuit 22 checks the signal 23 from the TC sets (A),(B), and (C) that they are only one. If it is good, the single selection excellence signal 24 representing that the selection is one set is distributed to only one of the control transmission circuits 19 to 21 corresponding to the excellent selection signal, and the control transmission circuit receives the unit selection data with this signal 24 and transmits it to the slave station K.
