One of the following two methods can be used.
<Method 1>
Directly set (write) the parameters in the QD75MH using
GX Configurator-QP.
<Method 2>
Set (write) the parameters from the PLC CPU to the
QD75MH using the PLC program (TO command).
Using GX Developer, set the control data and create a
PLC program to enable/disable the manual pulse
generator operation. (Set the control data in the QD75MH
buffer memory using the TO command.)
Write the PLC program created in STEP 1 and
STEP 2 to the PLC CPU using GX Developer.
Write "1" in " Cd.21 Manual pulse generator enable
flag", and operate the manual pulse generator.
One of the following two methods can be used.
