PURPOSE:To output device selecting information even with the selection from a computer, by controlling a selecting buffer relay circuit controlled with an output from a remote monitor control panel also with the output from the electronic computer. CONSTITUTION:A selection signal from a monitor control panel 2 and that from the electronic computer 4 are switched by using a selection signal switching device 9. In selecting a device selection switch SW11 of the panel 2, an individual selection relay 11 is driven with a path reaching the N of a power supply 3 via 2c, 2b of the device 9. Thus, a group selection signal G1, an individual selection signal U1 and device selecting information 101 to external parts are outputted. Further, in selecting with the computer 4, the device 9 is switched into the inverted position with the position above described. In closing contacts G1R, U1R of the computer 4 corresponding to the switch SW11 in this state, the individual selection relay 11 is driven with almost the same path as above. |
