NOTE: To read Echelon meters over PLC, you need Echelon Data Concentrators, and to read Echelon Data Concentrators, you need an Echelon NES Server.
PNPSCADA does interface directly to Echelon NES Servers via a pure SOAP interface. It assumes you se the server to automatically generate orders to read meters. It then looks up the results of those orders as needed.
IF you do not have access to a NES Server, there are some providers that has their own NES Server and give you access to the meters via their own Web interface. One of those is UAS or U Systems, as they are called in 2022. If you connect to your Echelons via UAS, the rest of this port is for you:
You need to add your UAS account. It is under: File->New->Servers->UAS Echelon NES Account
UAS must give you a CustomerID and password. The User-defined name you can make anything: it is just for you to be able to distinguish your entities from each other.
The meters will be created automatically as UAS Push updates to the server. You must give the domain name of your server to UAS, e.g. Adam.pnpscada.com
The way UAS pushes updates to the pnpscada server, is through a SOAP web service. You can browse the wsdl at /soap on any pnpscada server. E.g. https://adam.pnpscada.com:445/soap
The NES web service name is NESserviceSoap12. The function in the service that they use for pushing updates, is AcceptDoc. This pushes a big string to pnpscada, which contains XML.
One of the XML elements passed in the push, is one called
This is the CustomerID you specify when adding the UAS account. It is how we identify that the meter that is being pushed, belongs to you.
