Abstract

PURPOSE:To facilitate change of control sequence of network control unit NCU and MODEMs by performing sequence control without change of the main program of the system by change of the code table. CONSTITUTION:Since control of NCU and MODEMs is restricted to decision of the input signal, operation of the output signal, set of a timer, etc., code set of the code table is so constituted that the most efficient code for these operations may be assigned. The code set is stored in the ROM, where the main program is stored, or another ROM, and the code set is changed by exchange of the ROM or rewrite. In this case, system control unit SCU issues a command to module control unit MCU, and MCU decodes the command to control the control object element and returns response to SCU; and the relation between SCU and MCU is defined as this relationship between master and slave. Then, the code set stored in the ROM of MCU, and the code of the code set is read by CPU of the module control unit.
