Abstract

PURPOSE:To perform continuous execution of a sequence program without the designation of a jumped address for a microcontrol data by selecting a storage area with the operation code of the sequence program. CONSTITUTION:A sequence program is read out with a microcontrol data stored in an address A1+2 of the 1st storage area of a microprogram memroy 20 at the start of operation, branched to a storage area in accordance with the instruction word of the sequence program and the readout of the microcontrol data is made. When the readout is finished, since a counter 21 is reset to zero with the microcontrol data, the readout address is shifted to the head address in the same storage area to read out the next sequence program and the data is branched with the instruction word of the readout sequence program for the processing in accordance with the instruction word.
