ABSTRACT:
In a programmable sequence controller, a memory stores an auxiliary function decoding program comprising command information and address information. A comparator circuit capable of a simultaneous comparison of a plurality of bits is operatively connected to an external numerical control device to receive auxiliary function data therefrom and connected to receive address information of the decoding program for comparing the auxiliary function data with the address information of the decoding program. A logic operation circuit included in the programmable sequence contoller is operatively connected to the comparator circuit to examine the comparison result of the comparator circuit based upon command information of the decoding program, whereby the auxiliary function data is decoded.
