OpenLNS is now called IzoT Net Server.
 
Supporting OpenLNS applications and OpenLNS  Plug-ins:
 We currently do not have a OpenLNS SDK or IzoT Net Server SDK.  A 
OpenLNS/IzoT Net SDK is not needed to create a OpenLNS application.
 Differences between LNS an OpenLNS/IzoT Net Applications.
1. LNS used a LNS ADK (mainly documents and examples) to develop the 
app and required a runtime license for each LNS server.  To distribute 
your LNS app you needed to use the LNS Retribution kit (RDK) to provide 
your customer a LNS runtime license.
2. All OpenLNS servers come with a runtime license so the LNS RDK is not needed.
3. A LNS program written using the LNS Turbo ADK should work with a 
OpenLNS server with little or no problems, though you may get some 
errors when accessing the device credit information.  
4. LNS and OpenLNS Plug-ins use the LNS Plug-in Framework Developer's Kit.
 
Summary:
1. You do not need to wait for OpenLNS SDK to be available in order
 to develop OpenLNS applications. You can start developing applications 
today.
2. Change your LNS code to either not look for LNS credits or use a
 try-catch to not crash your program when it is tries to check for an 
non-existent LNS credits (IzoT Net Server and OpenLNS do not use device 
credits). The rest of your application also needs to work even though it
 doesn't get any device credit info
3. If you are developing a native OpenLNS application, all you need
 is the COM OCX: lcaobjsv.ocx and it is available with your OpenLNS 
Server install today.
4. If you are developing .NET OpenLNS director applications, then 
you need to use Echelon.LNS.Interop.dll as a reference in your project 
and distribute it with your product. You already have this dll 
Echelon.LNS.Interop.dll today with your OpenLNS Server install. But you 
do not have the merge modules yet, merge modules will only be available 
with a OpenLNS SDK (which is not availble).
