IoT-based energy management in manufacturing

Improving energy efficiency is a team effort. However, to be able to involve and inspire all concerned parties to a reasonable extent, energy consumption must be presented in a clear and comprehensible manner. The IoT-capable EMpro energy measuring devices and the intuitive, flexible features of the IoT-based EMMA energy management service help with simple, cloud-based data collection and targeted, meaningful visualization.

The benefits with IoT-based energy management

  • Easy and fast retrofitting of energy measuring technology using IoT-capable EMpro energy measuring devices, which can be connected directly to the IoT cloud environment via Ethernet interface through a plug-and-play principle
  • The energy manager can collect energy data with little effort and immediately visualize it graphically, without programming or necessary expertise
  • Tracking of energy data and key figures offers the opportunity to make production more efficient
  • Continuous improvement process through full transparency of energy data and thus uncovered efficiency potential

IoT-capable energy measuring devices deliver data automatically directly to the Proficloud

Automated data transfer to

In order to be able to display the energy consumption of various assembly groups more transparently, Phoenix Contact has equipped a production area at its Blomberg location with IoT-capable EMpro energy measuring devices. The energy measuring devices automatically transmit the measurement data to Phoenix Contact's "" IoT cloud environment.

The EMMA energy management service on Proficloud

Energy, Monitoring, Management, Analytics: EMMA is the smart energy management service from Phoenix Contact. EMMA focuses on the energy manager as the user and is tailored precisely to their needs. With a simple, intuitive design, EMMA provides a flexible spectrum of functions in the field of electrical energy and power data visualization for monitoring, analyzing, and evaluating this data.
EMMA thus supports energy managers proportionally in the check step of the PDCA cycle (Plan, Do, Check, Act) in accordance with the international standard ISO 50001:2018 (Energy management systems – Requirements with guidance for use).


The IoT-capable EMpro energy measuring devices and the EMMA energy management service in are a future-oriented solution. The system combines the benefits of the Industrial Internet of Things, sophisticated measurement technology, and constantly evolving smart services.
