(4) Precautions
Initial device values also take effect when the CPU module status is switched from STOP to RUN. Therefore,
they cannot be used for the data that are to be changed in a program after being set at CPU module power-on
from off. Use an instruction such as the MOV instruction in the main routine program so that the initial device
values are set to the specified devices. For the intelligent function module, use the TO instruction to write data to
the buffer memory.
