* 1 : Not supported by the AnS series compatible special function modules.
* 2 : Represents the program using the intelligent function module device, the FROM/TO instruction, or
the instructions dedicated for intelligent function modules.
* 3 : Indicates the case where the RUN/STOP switch (RUN/STOP/RESET switch of the Basic model
QCPU) is set from STOP to RUN (RUN LED flickers) to STOP to RUN.
POINT
1. The data used for communication with the intelligent function modules (initial
setting, etc.) are stored into the CPU module.
Refer to Section 5.1.1 and Section 5.2.1 for the storage destination in the
CPU module.
2. To enable the initial settings made by GX Configurator to be ensured by
powering the PLC OFF and then ON or resetting the CPU module, set the
RUN/STOP switch (RUN/STOP/RESET switch of the Basic model QCPU) to
RUN, and then power the PLC OFF and then ON or reset the CPU module.
