SATEC power meters and energy analyzers support a wide range of communication protocols, so they integrate cleanly into SCADA, BMS, EMS and substation automation systems. This page gives an overview of each supported protocol, links to the dedicated pages, and the model-specific register maps and communication guides.
Modbus
Modbus (RTU and TCP) is the most widely used protocol for integrating power meters with SCADA, PLCs and energy-management software. Most SATEC meters support Modbus, with per-model register maps available for PM180, PM135, PM130 PLUS and others.

DNP3
DNP3 is common in utility and substation environments. See the dedicated page: DNP3 meter for reliable communication for details and the full list of model register maps.
IEC 61850
IEC 61850 standardises substation communication and data models. See IEC 61850 and the future of substation communication for supported SATEC meters and PICS/communication guides.
IEC 60870-5 (101 / 104)
IEC 60870-5-101 and -104 are widely used for telecontrol between substations and control centres. See IEC 60870-5 for power system communication for the supported models and guides.
BACnet
BACnet connects metering into building management systems. See BACnet meter integration for building-system integration and the BFM series guide.
Profibus
Selected SATEC meters (e.g. PM135, PM130 PLUS, EM132/EM133) also provide Profibus communication guides for legacy industrial networks.
Secure and Dual-Use Communication
For defence, critical-infrastructure and dual-use applications, meter communications must be secure and controllable. SATEC meters support standard industrial protocols that can be deployed within secured, segmented networks, so metering data is exchanged reliably without exposing the control environment.
Choosing the Right Protocol
- SCADA / telecontrol – Modbus, DNP3 or IEC 60870-5
- Substation automation – IEC 61850
- Building management (BMS) – BACnet or Modbus
- Energy-management software – Modbus / TCP to ExpertPower
Protocol availability depends on the selected meter and version; confirm from the product specification.
Frequently Asked Questions
What communication protocols do SATEC power meters support?
Depending on the model, SATEC meters support Modbus (RTU/TCP), DNP3, IEC 61850, IEC 60870-5-101/104, BACnet and Profibus, for integration with SCADA, BMS and energy-management systems.
Which protocol should I use for SCADA integration?
Modbus, DNP3 or IEC 60870-5 are typical for SCADA and telecontrol; IEC 61850 is used for substation automation.
What is the difference between Modbus and DNP3?
Modbus is simple and universal for general integration; DNP3 adds features suited to utility and substation telecontrol such as time-stamped events and reporting by exception.
Where can I find the register map for my meter?
Model-specific register maps and communication guides are linked from each protocol section above and from the dedicated protocol pages.
