PURPOSE:To execute a partial correction of a program by inputting a program prepared in advance, through an interface means, storing it in a nonvolatile memory, and also, providing a display device of the contents of the memory and a key input device. CONSTITUTION:A CPU 1 and a CPU 2 use a data bus 5 and execute mutual communication by a serial transfer. To the master CPU 1, a CPU 3 is connected by a bus, and also, to its CPU 3, connectors RXDI, II, TXDI, II of full duplex 2 channels selected by a dip switch DIPSW, and they are connected to a computer of the outside, by which information such as a program and a data, etc. can be loaded easily to a memory. Also, the contents of the memory are displayed on indicators 11, 12, etc. on an operating panel through the CPU 1, the CPU 2, and a driver 9, and also, an operation of an operating key on the operating panel is transmitted to the CPU 1 through a buffer 13, and the CPU 2, and rewriting of the contents of the memory can be executed, therefore, a partial correction of the program can also be executed easily. |
