OVERVIEW OF PROCESSING PERFORMED BY THE QnACPU
12.1 Program Execution Types
Programs to be executed by the QnACPU are stored in the built-in RAM of the CPU
module or in a memory card.
While all of the data can be stored as one program in the built-in RAM or a memory card,
they can be also divided into several programs based on control units and stored.
When programming is undertaken by more than one designer, all the programming
process can be divided into several parts based on the processing units for each designer
and all of the programming data can be stored in the built-in RAM of a CPU module or a
memory card.
When dividing a program data into multiple programs, set "execution type" for each
program in program setting in the parameter mode of GPP function.
The QnACPU executes each execution type program in order of setting.
There are four executions types: "Initial execution type", "Scan execution type", "Low-
speed execution type", and "Standby type".
Initial execution type
: Program executed only once when a PLC is powered ON,
when a CPU module is reset, or when the RUN/STOP key
switch of the CPU module is switched from STOP to RUN.
(Refer to Section 12.1.1)
Scan execution type
: Program that is executed once per scan, starting from the
next scan after execution of the initial execution type
program.
(Refer to Section 12.1.2)
