Parameter initialization takes about 10 seconds. (Up to 30 seconds are sometimes
required.)
Do not turn the power ON/OFF; reset the CPU module, etc., during parameter
initialization. If the power is turned OFF or the CPU module is reset to forcibly end
the process, the data backed up in the flash ROM will be lost.
[4] Parameter initialization method
(1) Parameter initialization is carried out using the dedicated instruction
"ZP.PINIT".
(Refer to CHAPTER 14 "DEDICATED INSTRUCTIONS" for details.)
(2) Parameter initialization can also be carried out by the writing of the data
shown in the table below to the buffer memory using the TO instruction
/intelligent function device.
The initialization of the parameter is executed at the time point the data is
written to the QD75 buffer memory.
