Message table
When the message file is stored in multiple projects, one message table will be created by combining the operator message
data in the message file of each project.
When the operator message data with the same index in multiple projects are written, the message of the message file stored
in the project with small project No. will be displayed.
[(Example 1) When the message data do not overlap]
Project 1
Message file
;O, 0, 10, Project1 Msg01;
NOPLF
END
Project 2
Message file
;O, 1, 20, Project2 Msg01;
;O, 511, 21, Project2 Msg02;
NOPLF
END
[(Example 2) When the message data overlap]
Project 1
Message file
;O, 0, 10, Project1 Msg01;
;O, 1, 11, Project1 Msg02;
;O, 511, 12, Project1 Msg03;

END
Project 2

;O, 0, 20, Project2 Msg01;
;O, 1, 21, Project2 Msg02;
