Loytec LPA
Cause
A Loytec LPA can be a valuable troubleshooting tool to diagnose communication problems on a LON fieldbus.
Resolution
As the Automation Server uses Loytec's Lon chip, it is possible to use Loytec's LPA software over the Lon port on the AS.
You need a license to use the LPA software. You either need the "LPA-IP" or the "LPA-IP-SW" package depending on your setup. Here is a product overview on Loytec's home page. Here is a link to download the software. You need to create a free login in order to download software from Loytec's home page.

There is a limitation when using LPA through an AS. Refer to Not all traffic on a segment is captured when using the LPA through an Automation Server
Please make sure that you have a LonWorks interface configured in the Automation Server before proceeding. You will also need to add a Local Node to the interface and to commission it.
