New main features of the dOPC version 5

• dOPC is now compatible with OPC UA (Unified Architecture). Which means you can now easily build OPC UA client programs for Windows, Android, iOS and MacOS.
• Version 5 works only with Delphi and C++ Builder XE version 10 (Seattle) or higher, version 4.36 still works with older Delphi and C++ versions.
• This version currently does not support Free Pascal (www.freepascal.org), but version 4.36 still works with Free Pascal.
