Klaus Böhmer: Data must first be generated, which is done primarily via sensors that monitor machine conditions and processes. Today, automation solutions exclude key components like power supplies. In addition to parameters and status data, the consumption data of connected components are crucial. In a temporal context, normal behavior and deviations can be determined and any necessary measures can be derived. This makes the ability to communicate a core component of modern power supplies.

Jürgen Pfeifer: The optional plug-in communication interface – designed, for example, as an IO-Link interface – and the configuration and diagnostics options of the new WAGO Power Supply Pro 2 now take the user one step further into the digital age.

Klaus Böhmer: Yes, absolutely! Digitalization is only systematically implemented when my automation solutions provide enough data to build a virtual image. Our Pro 2 Power Supplies are now integral parts of this process. In addition to the numerous configurable options that determine the power supplies’ behavior in certain situations, the permanently determined data allow the generation of warning and error messages. This prevents damage (e.g., by triggering the built-in electronic fuse) or helps quickly react to short-term load changes via TopBoost or PowerBoost. These procedures describe the state of the connected circuit and its loads. Without communication, this world is closed to the user – and it would be a pity!

Klaus Böhmer: With the options just described, the user can react immediately and effectively upon leaving a normal state. This can save enormous costs because downtimes can be minimized or even avoided. Preventive maintenance can be initiated, which leads to improved efficiency while saving costs and resources. Since our communication module is pluggable, the same power supplies for different fieldbus protocols can be upgraded. We have transferred our basic #openandeasy approach, which applies to our controllers, to our power supplies.

Jürgen Pfeifer: The challenges are many and include relieving the PLC of data that is not directly needed for the application to work. Furthermore, it's also challenging to interpret the data with respect to the application. Here, WAGO can assist with an IoT partner network and analytics experts when needed.

Klaus Böhmer: The benefits of power supply communication are obvious. We and our customers have a plethora of ideas about all the possible applications that can still be realized with such intelligent power supplies. A treasure trove of possibilities, wherein the challenge is setting the right priorities. And it's a challenge that I welcome!
