Abstract

PURPOSE: To make it possible to select freely the kind and number of controlled units, by reading out a microprogram suitable for controlled units on the basis of the assignment contents and control requests of unit assignment circuits in controlled units.
CONSTITUTION: Controlled units 9-1...9-4 are ocntrolled by microprogram controller 6, and a microprogram for controlling units 9-1...9-4 is stored in control memory 7 in controller 6. Further, a unit-kind discriminator circuit is provided into controller 6 and unit assignment circuits 10-1...10-4 are equipped in units 9-1...9-4. Here, controller 6 when controlling units 9-1...9-4 reads out a program suitable for units 9-1...9-4 on the basis of the assignment contents and control requests of circuits 10-1...10-4 in units 9-1...9-4. Consequently, the kind and number of controlled units can be selected freely without changing connections between controller 6 and units 9-1...9-4.
