Abstract
PURPOSE: To increase the freedom at the input and output unit side, by reducing the processing in module level for CPU, by reading out the module level written in the input and output unit designated to the register of the input and output unit repeating the interruption via the bus.
CONSTITUTION: The specified input and output unit is designated among the input and output units 30,31,40,41 from CPU 2, the module level is written in the registor of the multi-input and output controllers 3 and 4 corresponding to the input and output unit designated and also to the registers of all the input and output units. Further, when write-in is returned from the input and output unit other than the input and output units designated to CPU 2, the module level written in the register of the input and output unit designated is read out on the register of the input and output unit returning the interruption through the K bus 1. Thus, the processing in the module level of CPU can be reduced and the freedom in the input and output unit can be increased.
