11.3.2 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 the GPP function
software package.
* Using the GPP function software package, set the control
data and create a sequence program to enable/disable
the manual pulse generator operation. (Set the control data
in the AD75 buffer memory using the TO command.)
* One of the following two methods can be used.
<Method 1>
Directly set (write) the parameters in the AD75 using the
AD75 software package.
<Method 2>
Set (write) the parameters from the PLC CPU to the AD75
using the sequence program (TO command).
