1.8 What is a Sequence Program?
The sequence program is a scan execution type program written in the language commonly used for the motion
program.
An application to cyclically check a status, such as an interlock, can be created by using a sequence program.
A sequence program can be executed by calling from the program execution registry screen dialog box of M-
EXECUTOR Module.
Note: The M-EXECUTOR Module can not be used with the following modules and Machine Controllers:
MP2300, CPU-01, CPU-02
A total of up to 256 sequence and motion programs can be created.
An example of a sequence program is shown below.
The features of sequence programs are described, starting from the next page.
