Industry 4.0 introduces further challenges, understood as follows by ZUMBACH:
- M2M communication (machine-to-machine communication)based on established standards
- M2H communication (machine-to-human communication) based on platform-independent display devices and standard software
In the field of M2M, customer fieldbuses are particularly supported, in compliance with standards and the measures required for certification. Beyond this, OPC UA integrated in USYS processors as well as in PROFILEMASTER®, STEELMASTER, RAYEX®, SIMAC® and others are available to customers (see separate OPC UA leaflet). Using the new OPC server gateway software, the majority of terminal devices can also receive data via OPC UA. OPC UA is a key element of Industry 4.0 and the Internet of Things (IoT). It enables horizontal and vertical integration across various levels of the automation pyramid, from the sensor to the ERP system.
Web server applications are the key priority in the M2H field; they are already offered in some systems today and will become universal
in the future. In this context, too, OPC UA can form the basis for efficient M2H solutions thanks to common industrial interoperability
