Message table

data in the message files of each project.
When the alarm message data with the same index are written in multiple projects, the alarm message of the message file
stored in the project with the small project No. will be displayed.
[(Example 1) When the message data do not overlap]
Project 1
Message file
;A, 0, 10, Project1 Msg01;
NOPLF
END
Project 2
Message file
;A, 1, 20, Project2 Msg01;
;A, 1023, 21, Project2 Msg02;
NOPLF
END
