The OPC technology presents a standard for visualization and monitoring systems to access field level data. By this standardized interface SCADA systems communicate with PLCs and field busses, production level data are thus integrated into office applications. Even data exchange with other field bus systems is made this way.
OPC server operates in a client/server architecture. The Easylon OPC Server for LON runs on a PC at the LonWorks network. It provides, in an always updated database, information about the LonWorks network objects (nodes, network variables) as OPC objects and realizes packaging, conversion and update of these objects.
As server the Easylon OPC Server accepts subscriptions from several clients and takes care of updating subscribed NV’s as soon as their values change within the LonWorks network or due to external settings.
The Easylon OPC Server enables any OPC Client to access the LonWorks network. It is compliant with the OPC Data Access Specification. Compatibility with many clients has been proven in hundreds of customer applications all over the world and in special interoperability workshops of the OPC Foundation
Next to the use with standard client software for visualization simple client solutions can easily be realized. Examples for use with Office programs and Visual Basic are provided.
Of course the LON OPC server can be simultaneously used by several clients. As customary with OPC, clients on other PCs can access the Easylon OPC Server via the PC network.
The OPC Server M is a Windows applications for PCs with Windows NT and later. It can operate at any unknown network.
A Demo version is available for download. It offers full functionality, however, with a limited runtime. By purchasing a license key this version can be activated for regular operation.
There are large networks and small ones. Therefore the Easylon OPC Server can be licensed in different scales, depending on the number of NVs monitored. Details you will find in the price list.
The license key is coupled to the Neuron-ID or node-ID of the network interface.
