Softing's 'uaToolkit Embedded' for the implementation of embedded OPC UA servers with client/server and publisher/subscriber communication has a UADP publisher with information model and a UADP subscriber in the current version 1.20. The toolkit has been certified in the OPC Foundation Compliance Lab for the Nano Embedded Device Server profile, the Micro Embedded Device Server profile and the Embedded UA Server profile. It also supports OPC UA Companion specifications with a tool for importing OPC UA nodesets. According to the company, the toolkit is characterized by low memory requirements and low computing power requirements. This makes it particularly suitable for the firmware development of field devices, but also for use in control or remote I/O systems with limited resources.
