3.5 PLC Program Development Procedure
3.5.1 Precautions before Development
Pay careful attention to the following items before developing ladder programs using the GPPQ.
(1) PC Type Selection
The PC type must be set when newly creating programs, etc. Select the following CPU type when
requesting PC type selection with the GPPQ. An error will occur during transfer of the ladder
program to the C64 controller if another PC type is selected.
CPU type: Q4A
(2) Device Setting
Do not set the devices when developing in the ladder program for the C64 controller. Develop the
program with the device settings (No. of points, etc.) left at their default values applied when GPPQ
was started. The ladder program cannot be transferred to the C64 controller normally when it is
developed with settings other than the default values.
Do not set the devices.
(3) PLC Commands
MELSEC-specific PLC commands cannot be used in the ladder program development for the C64
controller. Only M500 equivalent PLC commands and formats can be used.
The format, etc., changes with some commands. Refer to "3.7 Differences from the M500 PLC
development environment" for details.
MELSEC-specific PLC commands cannot be used.
