11.4.2 Manual pulse generator operation execution procedure
The manual pulse generator operation is carried out by the following procedure.
Write the sequence program created in STEP 1 and
STEP 2 to the PLC CPU using GX Developer.
Using GX Developer, set the control data and create a
sequence program to enable/disable the manual pulse
generator operation. (Set the control data in the QD75
buffer memory using the TO command.)
One of the following two methods can be used.
<Method 1>
Directly set (write) the parameters in the QD75 using
GX Configurator-QP.
<Method 2>
Set (write) the parameters from the PLC CPU to the QD75
using the sequence program (TO command).
