Abstract

Improvements in sequence controllers, characterized in that each controller comprises a memory for storing a sequence program formed by a series of instructions respectively identified by their memory addresses, each of these instructions having an examination command and address information; a logic operating circuit for examining an external input with said exam command; an input module for applying the external input to the operating logic circuit in accordance with the address information; an output module for transmitting a control signal based on the result of the examination of the operating logic circuit; suspending means in the operating logic circuit for suspending the next examination of a logical function from a group of logical functions in response to the result of the preceding examination of a logical function thereby executing a logical operation non-sequentially.
