Although wireless characterises the IoT, networking using standard fieldbus technologies is far from being a thing of the past. On the contrary: combining the two means speed and reliability – and often cost-efficiency as well.
We have been using a wide variety of fieldbuses for automation and building automation for more than 25 years – from simple 2-wire buses with their own supply to Industrial Ethernet standards such as EtherCAT. We already have the software for a range of communication protocols in our modular system. This keeps the development risk to a minimum and allows us to implement secure communication modules within a short period of time.
OPC UA and MQTT also form part of our networking portfolio as middleware for automation – from simple data polling to complex integration of XML files and information models with OPC UA.
