• Build DLLs which can function as an OPC UA AC (alarm conditions), Historical Access; Classic OPC DA A&E(Alarm & Events) HDA (Historical Data Access) client & server each. Support full functionality of OPC UA current version. The Servers will work against boolean data as Alarms or events or MS SQL Server database. The DB schema will be provided. Deliver the OPC DA A&E (classic) server first.
• A test application that will work with some 3rd party Historian that supports OPC. Allow us to test the finished solution with it also. Must specify the Historian intended to be used.
• A OPC UA client & server in .NET standard.
• The DLLs must not just be the examples downloaded off some web site which don’t have the source code.
• Need full source code for the internal part of the server & client. We need this source code in case we have errors or need to do optimization later.
• It can have dependencies on PUBLIC and FREELY, UNENCUMBERED AVAILABLE libraries if necessary.
• Works with latest .NET framework & Builds in latest MS Visual Studio as a .net standard library (preferred). We already have the UA data access version built.
More info on OPC may be obtained from OPC Foundation website.
