Abstract

PURPOSE:To execute the test, by writing a test control word group of a form different from that of a control word group from the control panel of a control device to a buffer and regarding this generated control word group as the control word group read out from a main storage to control an object to be controlled. CONSTITUTION:An input/output port 11 of a control device 2 interrupts a microprogram by a sequence circuit 18 on a basis of the command of a central processing device. The interrupt source is investigated by a branch condition selecting circuit 19 on the microprogram; and the interrupt source is the input/output port 11, a control word group stored in a main storage is read out to an internal buffer 13 by a microporcessor 16. If the interrupt source is a control panel 20 and indicates the write of a control word group, the indicated value is written in an area of the buffer 13 where the control word group should be stored. If this interrupt source indicates the execution of the test, the microprocessor 16 and a control circuit 14 of the buffer 13 are used to generate a normal control word group from the control word group for test.
