Energy monitoring guide
IIoT energy monitoring: every panel meter, live, inside your plant.
An IIoT energy monitoring system reads the meters on your panels every few seconds and turns them into live readings, history, alerts and bill figures. Here is how one works in a factory, what it can show you, and what to check before you choose one.
What IIoT energy monitoring is
IIoT stands for Industrial Internet of Things: industrial equipment connected so its readings can be collected and used. In energy monitoring, the equipment is the multifunction meters (MFMs) on your incomer and feeder panels.
A system has three parts:
- Meters on the panels, measuring voltage, current, power, power factor and energy.
- A gateway that reads every meter over a wired Modbus RTU (RS-485) network and records the history.
- A dashboard on a phone or laptop that shows the readings live and turns them into Maximum Demand, power factor, bill and savings figures.
Most panel meters already have an RS-485 port. A plant with meters installed is usually one wiring job away from live monitoring.
What you can monitor
| Area | What it shows | Guide |
|---|---|---|
| Load and demand | kW, kVA and current per panel; peak intervals; base load | Load monitoring |
| Maximum Demand | The running 15- or 30-minute interval against Contract Demand | Reduce MD |
| Power factor | Lagging or leading PF, and what it adds to a kVAh bill | Improve PF |
| Supply quality | Voltage, frequency, unbalance and harmonics | Power quality |
| Machines | Running, idle, stopped and overload time | Running and idle |
| Departments and lines | Energy per panel, with the totals adding up | Sub-metering |
| Solar and DG | Each source against the plant load | Solar, DG and grid |
It works with the meters you already have
You do not need to replace working meters. Panel meters from brands such as Schneider Electric, Secure Meters and HPL read over Modbus RTU, and single-phase meters connect too. Where a panel has no meter, one is added on that feeder. See which meters connect.
Cloud or on-premises
Many IIoT platforms send every reading to the vendor’s cloud. An on-premises system keeps the meters, the history and the dashboard inside the plant, and still lets owners open it from anywhere over an encrypted private network. Recording and alerts carry on when the Internet is down. The full comparison is in on-premises energy monitoring.
What it pays for
The money in an industrial electricity bill is rarely in the units alone. It sits in the demand charge, power factor, time-of-day rates and loads left running when nothing is being made. Monitoring shows where each of these happens, panel by panel and hour by hour, so the fix goes where the money is. The eight places a factory bill leaks money explains each one.
Questions to ask before you buy
- Does it read our existing meters, or does it need new ones?
- Where is our data stored, and what keeps working without the Internet?
- Does it calculate Maximum Demand the way our DISCOM does, on 15- or 30-minute intervals?
- Can it show the bill in our tariff’s terms: kVAh, TOD zones, power factor?
- How long is full-detail history kept, and can we export it to Excel?
- Can it grow from one panel to the whole plant, and to more than one plant?
How KONDUKTOR® EMS works
KONDUKTOR® EMS gateways read the meters on your panels over Modbus RTU, up to 10 meters per gateway, with more gateways added as the plant grows. Each gateway records years of history on site and serves the dashboard on your plant network. Nothing is sent to KONDUKTOR or to any cloud server.
- Live readings, alerts, running Maximum Demand, power factor and bill estimates.
- Panel hierarchy, machine running and idle time, solar and DG views.
- Excel and CSV export, and remote access for owners with no cloud server in between.
The same RS-485 network carries more than meters: vibration and temperature sensors, and Modbus I/O cards for automatic control, are added and configured for your plant as part of your project.
Common questions
What is the difference between IoT and IIoT energy monitoring?+
IIoT is IoT built for industry: wired networks such as Modbus RTU on RS-485, panel meters instead of plug-in sensors, and readings meant to run a plant. IIoT energy monitoring reads the multifunction meters on your panels and works in a factory’s electrical noise.
Does IIoT energy monitoring need the Internet?+
Not with an on-premises system. The gateway reads the meters, records the history and raises alerts on site, and the dashboard opens on the plant network. The Internet is needed only to view it from outside the plant.
Can it use our existing meters?+
Yes, if they have an RS-485 Modbus port, as most panel multifunction meters do. A panel without a meter gets one added on that feeder.
How many meters can one system read?+
A KONDUKTOR® EMS gateway reads up to 10 meters. Larger plants add gateways, and all of them appear in one dashboard.
