PURPOSE:To execute a specified program, by shifting control to a specific address at the start of operation of a controller and loading either one of data and diagnostic cassettes to one connector. CONSTITUTION:In loading the data cassette 30, an MPU11 picks up an instruction stored on an address (g) of an ROM12a. A control signal is outputted from a control terminal C0 of the MPU11 with this instruction, an ROM31 is made operative and address signals A0-A10 selecting a specific address (p) are inputted, and the instruction stored in the specific address (p), i.e., an address h1 of the ROM12a receives control. In loading the diagnostic cassette 40, the MPU11 picks up an instruction stored in the address (g) of the ROM12a, outputs a control signal from the control terminal C0 to shift the control to the specific address (p) and executes a diagnostic program N. |
