Sample-Server-asyncio

OPC UA Sample Server based on FreeOpcUa/opcua-asyncio

Prototype implementations of OPC UA Companion Specifications

Based on the Hannover Messe 2021 demonstration of the VDMA Group OPC UA for Surface Technology.

This Sample Server implementation should help companion specification working groups to easily implement a first running server.

This repository provides a container image to be run by Docker as well as a running instance of the main branch at opc.tcp://opcua.umati.app:4842
