Customer Showcase: OPC UA@Weinig
basysKom supported the WEINIG Group during the development and implementation of the WWCS while using OPC UA and the open62541 stack: a customer showcase.

In this blog we explain how to provide OPCUA open62541 as a ffi plugin to Dart and use it in Flutter. We highlight the pros’ and give you the cons.
The umati community did its first open source release of the “umati Dashboard OPC UA Client”. To support this effort basysKom has worked with the umati community and ported the client to the open62541 OPC UA stack.
Companion specifications complement OPC UA with the goal of fostering interoperability. This article will provide an overview about implementing a Companion Specification with open62541.
So far programs using Qt OPC UA with the open62541 back-end produced quite a bit of chatter on stdout originating from the open62541 stack itself. Unfortunately there was no simple way to get rid of these low-level logs. We now provide a way to control this behavior.
The Qt OPC UA module has been ported to CMake and will be part of Qt 6 right from the first release.
In addition to numerous bug fixes and improved test coverage, the open62541 plugin has been updated to open62541 v1.1 and uses OpenSSL for security support, thus removing the dependency on mbedTLS.
basysKom recently extended this plugin to also accept PEM-based input. PEM is a file format used for certificates and keys which is specified by an RFC and is a preferred format for a lot of open source software. The pull request has been merged and our contribution is available from the 1.1 branch (and will also hit the master branch soon).
The open62541 OPC UA stack with its Pub-Sub extension now supports MQTT over TLS as well as MQTT-brokers requiring a login (contributed by basysKom). This allows the direct communication between open62541 and the Azure IoT Hub and therefore highly simplifies the connection of OPC UA based IoT Devices to the cloud.
We are developing innovative applications, provide comprehensive consulting, hands-on coaching, and qualificatory training for capital and consumer goods companies. Our customers value our agile approach, our transparent processes, and our high standards.
Due to our own knowledge and our extensive experiences we are convinced of the advantages of open source software for our customers.
