Abstract
A sequence instruction display system for use with a programmable sequence controller for displaying a desired sequence instruction and the on-off state of the input or output element corresponding thereto. A buffer memory is provided for storing input and output instructions along with the corresponding on-off states transmitted from a program memory of the sequence controller on an on-line basis with the scan of the program memory in the sequence controller. A numeric key is provided to designate an output instruction. A comparator, on detecting the coincidence of the designated output instruction with an output instruction transmitted from the sequence controller, outputs a signal so as to prevent the buffer memory from further storing the input and output instructions. A data display device displays at a time one of the input and output instructions along with the on-off state stored in the buffer memory.
