CHAPTER11 PROCEDURES FOR WRITING PROGRAM TO
CPU MODULE
This chapter describes procedures for writing a program created by GX Developer to the CPU module.
Remark
For procedures for starting the CPU module, refer to the following.

11.1 Items to be Considered for Creating Programs

To create a program, the number of device points, size, and file name of the program must be
predetermined.
(1) Program size
Check whether the total size of programs and parameters are within the program size executable in
the CPU module used.
Table11.1 provides the program size executable in each CPU module.

Q01UCPU
Q02UCPU
Q03UDCPU, Q03UDECPU
Q04UDHCPU, Q04UDEHCPU
Q06UDHCPU, Q06UDEHCPU
Q10UDHCPU, Q10UDEHCPU
Q13UDHCPU, Q13UDEHCPU
Q20UDHCPU, Q20UDEHCPU
Q26UDHCPU, Q26UDEHCPU
Whether parameters are stored to the program memory, standard ROM, or memory card can be set.
If the program size above is required for only programs, store the parameters in the standard ROM or memory
card.
(2)
Determining a unit for structuring the programs
When creating multiple programs, determine a unit (process/function) for structuring the programs
(3) Setting the execution conditions for programs to be created
When executing multiple programs, set their execution conditions to each program.
Without the setting, the programs cannot be executed.
