ABSTRACT:
A programmable sequence controller with a counting function comprises an addressable latch circuit including at least one flip flop. A counter is connected to the flip flop such that the content of the counter is changed by one each time the flip flop is set. A setting device is provided for manually setting a count-up value of the counter. A comparator generates a count-up value signal when the counting-up of the counter to the count-up value is detected. A data selector is connected to receive the count-up value signal for supplying a logical value indicative of the status of the comparator. A logic operation circuit is responsive to a test command of a first instruction for testing a logical value of one of a plurality of external input devices and the data selector specified by address data in the first instruction and also responsive to an output command in a second instruction for generating an output command signal based upon the result of the test. The flip flop is set in response to the output command signal generated from the logic operation circuit when the flip flop is designated by the address data.
