4. Time at which the settings become valid
1) When specifying the settings by parameters
When the PLC power is turned ON, the contents of parameters set on the parameter setting window
using sequence programming software are automatically transferred to D8120, D8129, D8400, D8409,
D8420 and D8429 in the PLC.
As soon as the parameters are transferred to the PLC, the settings become valid.
After the program parameters are transferred to the PLC, it is necessary to turn OFF the PLC power
once, and then turn it ON again.

2) When specifying the settings by writing data to special data registers
After writing a sequence program, set the PLC mode from STOP to RUN to write the preset data to
D8120, D8400, D8420 or D8370. After that, set the PLC mode to STOP once, and then set it to RUN
again. Or turn OFF the PLC power once, and then turn it ON again.
