PURPOSE:To simplify a circuit and save labor at the time of adjustment and maintenance by providing one transmission interface between one console and plural microcomputers and selecting one of the microcomputers according to the data sent from the console. CONSTITUTION:One transmission interface 5 is connected to a multipath 3 between one console 4 and plural (two in the drawing) microcomputers 1, 2. The transmission interface 5 and the transmission control switching parts 6 of the microcomputers 1, 2 are connected by a path line 8, and signals outputted from the transmission interface 5 are inputted into the microcomputers 1, 2 simultaneously and further inputted into monitor parts 7 through the transmission control switching parts 6. The multipath 3 and local paths 9 in the microcomputers 1, 2 are connected by multipath interfaces 10. The transmission control switching part 6 of the microcomputer 1 or 2 is selected according to the data from the console 4. The reconnection of the connecting line to the console 4 becomes therefore unnecessary, and labor at the time of adjustment and maintenance can be saved. |
