12.1.1 Initial execution type programs
(1) Definition
(a) The initial execution type program is a 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.
(b) The execution type is set to "Init" in program setting in the parameter mode of
GPP function.
(c) Initial execution type programs can be used for applications such as the initial
processing for a special function module, where once the program has been
executed, it need not be executed from the next scan.
*
(2) Execution of multiple initial execution type programs
If there are more than one initial execution type program, they are executed in
ascending order of the program numbers set in the parameter mode.
