High Performance OPC UA Client Server SDK/Toolkit

Fastest OPC UA Stack on the Market

New high speed OPC UA Stack for low resource consumption (embedded devices) and high performance operation. We have analyzed the issues and bottlenecks of today’s OPC UA implementations. We came to the conclusion that only a complete redesign can solve the issues to improve the performance, improve the scalability, and increase the security of OPC UA. This makes OPC UA usable in smallest devices and thus “IoT Ready”, and furthermore guarantees improved performance for high end servers, which must be able to handle thousands of connections in parallel.

With a new software architecture and new implementation from scratch we have achieved all these goals. Of course, the new implementation is still wire-compatible with the original OPC Foundation Stacks.

Requirements

To get the best portability the SDK only requires a C99 compatible
C compiler. Typically, GCC is used on embedded systems, but the
SDK compiles also with Clang or MS Visual Studio Compilers.

Minimal requirements:

  • C99 Compiler
  • RAM (min. 30 KB)
  • System Clock (ideally synced via NTP or SNTP)
  • TCP/IP Stack

Free UaModeler for  implementing CompanionModels and code generation included !
