High Performance Model Qcpu, Process Cpu, And Redundant Cpu; Items To Be Considered For Creating Programs - Mitsubishi 00JCPU User Manual

11.2 High Performance Model QCPU, Process CPU, and Redundant
CPU

11.2.1 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. (
Table11.2 provides the program size executable in each CPU module.
Q02CPU,Q02HCPU,Q02PHCPU
Q06HCPU,Q06PHCPU
Q12HCPU,Q12PHCPU,Q12PRHCPU
Q25HCPU,Q25PHCPU,Q25PRHCPU
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.
(4) Setting the applications of devices and the number of device points
Consider the applications of devices and the number of device points used in the program.
( CHAPTER 9)
(5) Setting the initial device value
Set data necessary as an initial value to the device memory and the buffer memory of the intelligent function
module. ( Section 6.27)
(6) Setting boot operation
When storing a program to the standard ROM or memory card, execute the program after boot operation.
For boot operation, make the setting in the Boot file tab of the PLC parameter dialog box.
