Appendix 3. PLC Development Environment using GPPQ
3.6 PLC-Related Data Development Procedure
The development procedure is explained here for alarm messages, operator messages, PLC
switches, etc., as PLC related data.
3.6.1 PLC Related Data File Names
The PLC related data is controlled and stored in the categories shown below inside the C64 Series.
Consequently, that data development is also carried out in each of the same categories.
[Important]
Be careful when transferring the message data. If message data that does not follow the
file name regulations below is transferred, it will be mistaken for the PLC program, and
the PLC program may be erased.
M1 xxxx. GPG
The data classification is distinguished by file name when transferring with the GPPQ.
The extensions express the file classification, and the two characters at the head express
the data classification and language classification.
xxxx can be freely designated within eight characters, excluding extensions.

∗ The PLC program and program comment are explained in "1.4 Creating PLC-Related
Data".
