Build the Scanlist
What This Chapter Contains Read this chapter to configure the scanner by building the scanlist.
The following table describes what this chapter contains and where to
find specific information.
Introduction With the Starter Kit, you are not required to create a scanlist and map
the device input and outputs. You can simply open the provided
network file (.dnt) for your Starter Kit and download the scanlist.
Everything is already done for you.
If you wish to create your own scanlist and map your devices to work
with the provided ladder logic, follow the steps in this chapter. If you
do not want to create your own scanlist and map the devices, open
the file, follow steps on pages 4-3 through 4-5 and go to Chapter 5.
For the Starter Kits, we first automapped all the scanlist devices, next
we made a few minor adjustments to the word allocations and made
only one change to the I/O parameters of one device. The Inductive
Proximity Switch I/O parameters have been changed from Change of
State/Cyclic to Strobed. This allows the switch to send an analog
value.
The ladder logic for each of the Starter Kits programs the devices in
exactly the same way. Although, each ladder programming tool uses
different addressing schemes and input/output filenames.
