Abstract

PURPOSE:To make the pursuit of causes to a failure convenient, for a process using a sequence controller, by adding a trigger condition deciding routine. CONSTITUTION:A function to set a trigger condition for a display screen 22 to be held with a keyboard 21 is added. To be concrete, a circuit element to hold the screen 22 and a changing condition, off-on or on-off are set. When this trigger condition is set, the program enters a trigger condition deciding routine 24, the status of the corresponding decision I/O is fetched from a sequence controller CPU, the result is collated with the deciding condition for the decision of coincidence/dissidence. If dissident, the program returns to a monitor processing routine 23, the process monitor is executed as it is and the status display is refreshed. If coincident, the program is not returned to the routine 23, but interrupted to hold the screen.
