PURPOSE:To cope easily with a change of a process display by installing a color change processing module to a process monitor processing of a sequence controller. CONSTITUTION:A sequence controller is constituted of process input/output devices 90, 100, a sequence input/output memory 80, a memory 40 for storing a sequence program 41, etc., a display part 60 and its control part 50, a CPU10, etc. In this case, a color change processing module 30 for executing a color change display based on the sequence input/output memory 80 and a color change data 42 is provided. This module 30 detects a state of color change coils 1-(n) in the sequence input/output memory 80, inputs color information and display information contained in the color change data 42 with respect to a place where a variation has been generated, outputs them to a display device control part 50, and executes a color change display of a plant flow. In this way, a color change monitor processing display of a process flow can be controlled by the sequence program, and it is possible to cope easily with its change. |
