PURPOSE:To shorten the control time and to simplify a control program by using a means which selects a group of adapters of the same type, and realizing the simultaneous control of these adapters. CONSTITUTION:The scan-in and shift end signals are transmitted to the adapters of the same type via a single scan loop and by means of a 1st means which selects the adapters of the same type of a register 13', and a means which secures connection between the input parts of an address register 24 consisting of a selection signal receiving part 26' and a data register 25 and the output parts of an address register 14 and a data register 15, respectively. Thus the simultaneous control is made possible to the adapters of the same type. As a result, the data processing time is shortened and a control program for a maintenance operation part is simplified. |
