This chapter explains a procedure for developing PLC-related data such as alarm messages,
operator messages, and PLC switches.

There are the following two methods as a general development procedure of message data.
1) Making conversion into GX Developer data using a general text editor or spreadsheet tool and
data conversion package.
(When there is a large volume of message data and you want to control them with a
commercially available tool, for example)
