There are two types of promoters used in Basic model QCPU's procedures: "PLC
parameters" that are used when operating a PLC and "network parameters" that are
used when connecting to the MELSECNET/H, Ethernet or CC-Link system.
This chapter shows a listing of PLC parameters and network parameters used for
GX Developer.
For details regarding each setting item, refer to the section or manual indicated.
For GX Developer setting procedures, see the GX Developer Operating Manual.
The parameters written from the GX Developer will be validated within the Basic model
QCPU in the following cases: ( 1)
• When the power supply to the PLC is switched on.
• When the Basic model QCPU is reset.
• When the Basic model QCPU changes from STOP to RUN.
1 The PLC parameter I/O allocation switch settings and detailed settings and the
network parameters will be transmitted to the target intelligent function module at
the following startup of the Basic model QCPU and will be used there.
• When the PLC is powered on
• When the Basic model QCPU is reset
POINT
(1) When the switch settings of the I/O assignment PLC parameters and the
network parameters have been changed, the PLC must be powered off, then on
(ON to OFF to ON) or the Basic model QCPU reset.
If the PLC is not powered off, then on (ON to OFF to ON) or the Basic model
QCPU not reset, the new switch settings of the I/O assignment PLC parameters
and the new network parameters are not made valid.
(2) When the PLC parameters have been written to the Basic model QCPU, power
the PLC off, then on (ON to OFF to ON) or reset the Basic model QCPU.
REMARK
When the Basic model QCPU is switched from STOP to RUN, the PLC parameter
I/O allocation switch settings and detailed settings are not transmitted to the target
intelligent function module.
