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.

Some Prerequisites:  

1. A license is required to use the LPA software. Either the "LPA-IP" or the "LPA-IP-SW" package depending on your setup.
2. LPA (loytec.com) shows a product overview.  
3. Downloads | Software - Device Firmware and Readme (loytec.com) to download the software. Create a free login in order to download software from Loytec's home page
4. For additional help

5. 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
