[Precautions]
(1) The PINIT instruction can only be executed when the QD75 READY signal (X0) is
turned OFF.
When the QD75 READY signal is turned ON, the PINIT instruction cannot be
executed.
Before executing the PINIT instruction, turn OFF the PLC READY signal (Y0) and
then turn OFF the QD75 READY signal.
When the QD75 READY signal is turned ON, the PINIT instruction cannot be
executed.
Before executing the PINIT instruction, turn OFF the PLC READY signal (Y0) and
then turn OFF the QD75 READY signal.
(2) When the remote I/O station (Q Corresponding MELSECNET/H network remote
