SEQUENCE CONTROL SYSTEM AND SEQUENCER DEVICE

PROBLEM TO BE SOLVED: To provide a sequence control system which can easily change sequence in response to change in control timing and reconfiguration of a control target device. SOLUTION: This sequence control system is equipped with: a control target device 101; a plurality of sequencer devices 102-104 which achieve a series of sequence operations by executing a sequence program to this control target device; and an external terminal 105. The external terminal 105 has a timing chart editing means 105c which edits a timing chart which specifies a sequence operation for the control target device; and a timing chart information generation means 105d to generate timing chart information for drawing the timing chart. The sequencer devices 102-104 have timing chart information setting means for setting the timing chart information as an operation condition of the sequence program. COPYRIGHT: (C)2008,JPO&INPIT
