In the industrial environment, solutions for Device and Update Management (DaUM) often use a specific process called a vendor to distribute files to proprietary devices and install them based on the manufacturer. With the DaUM service from Phoenix Contact, based on PLCnext technology, it is possible to manage and update automation devices regardless of their manufacturer. In this case, the devices can be PLCs, I/O modules, frequency converters, robots, network devices, power supplies or other components used in automation technology.
To enable this, the DaUM service uses standardised protocols such as OPC UA. It is not just this ability to update many different components within the automation system that is new, but also the fact that security is ensured consistently at all levels of the system. Any communication tasks or commands are only performed if they have been authenticated and authorised. Here, reference is strictly made to IEC 62443.
A further feature of the DaUM service is the option of being able to operate it at various levels. The service can be operated on an edge PC in the system, on a central server instance of the user or on an automation device, depending on the application and system size.

IT in Manufacturing
In recent years, the generation of data to create ever better transparency and control of production has become a decisive competitive factor. IIoT has also contributed to more manufacturing systems being connected to IT or cloud systems. This places higher demands on access security, which Phoenix Contact meets with the Secure Edge Box.

Editor's Choice PLCs, DCSs & Controllers
Many process engineers do not appreciate the importance of flow loops in their unit controls. A senior process engineer once told me that flow loops need not be tuned well, as they generally have little effect on the more important and much slower loops like temperatures and pressures.

PLCs, DCSs & Controllers
Data acquisition, data logging and data analysis are required functions for most modern industrial control systems. The simplest and lowest cost way to provide these functions is often by using the same platform that’s providing real-time control, namely the PLC or the programmable automation controller.
