Using Loytec LPA with SmartStruxure AS


How can you use Loytec's LPA software with the AS as the interface


Automation Server

Loytec LPA


A Loytec LPA can be a valuable troubleshooting tool to diagnose communication problems on a LON fieldbus.


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.

For help buying and registering the LPA software read Lessons Learned Article  #6243

For help troubleshooting Lon communication with TAC Xenta's, read Lessons Learned Article #4974

There is a limitation when using LPA through an AS. Refer to Lessons Learned Article #18069
