OPC development in F#
QuickOPC makes it easy for you to integrate OPC client functionality into your Visual F# solution. Reading a value from OPC Data Access or OPC Unified Architecture server, or writing a data value can be achieved in just one or two lines of code. You can also set up subscriptions and receive event notifications about data changes. What's more, in your OPC F# program, connections to OPC servers do not have to be created and recreated in case of a network failure or similar problems - QuickOPC handles this automatically, behind the scenes.
The components can be used from various environments: Code libraries, ASP.NET pages, console applications, Windows services, etc. are all supported. The F# development tool we have targeted primarily is Visual Studio.
- New: QuickOPC now also supports OPC UA Alarms&Conditions.
Simple OPC-UA F# Example Using QuickOPC
The code below (in F#) reads and displays a monitored item value, using QuickOPC:
The code below subscribes to changes of a monitored item value, and displays the value with each change:
OPC "Classic" Data Access, or Alarms&Events
No other product can do this in such a clear and concise code! The programming is straightforward, and the developer can focus on getting the work done and not on fighting the intricacies of OPC protocols.
Footnote & required disclosure: QuickOPC (including its Options) is a software development kit (SDK) for development of OPC clients. Installing QuickOPC or its Options does not change system settings.
