What Does Argus EMS Actually Do in the Field?
This page carries verifiable technical capability rather than a savings promise: the devices we read, the protocols we support and how the system runs in production.
Why Are There No Case-Study Figures Here?
In the energy sector, reference pages are usually full of percentages nobody can verify. A "14% savings" claim with no named facility carries no information for the reader: it cannot be verified, compared, or applied to your own site. We have chosen not to take that route.
Our customers' consumption and savings data is commercially sensitive, and our contracts do not permit publishing it. So below we publish only what is verifiable: which device we read over which protocol, which distributor portal we integrate with, and the conditions the system runs under. All of it can be tested against your own devices in a demo session.
If you would like a reference call specific to your type of facility, we arrange one directly with the relevant customer's consent. You can request it from the contact page.
Protocols We Read in the Field
| Protocol | Typical Device | What Is Measured |
|---|---|---|
| Modbus RTU (RS-485) | Energy analyser, reactive relay, meter | kWh, kVArh, current, voltage, power factor, THD |
| Modbus TCP | Chiller panel, gateway, PLC | Water temperature, compressor status, load %, alarm code |
| M-Bus | Water meter, calorimeter (heat meter) | m³ index, flow rate, heat kWh, flow-return temperature |
| SNMP | UPS, network device | Battery status, load, input/output voltage |
| OCPP | EV charge point | Charging session, energy delivered, connector status |
| MQTT (TLS) | Field unit ↔ server | Measurement transfer, remote configuration, health signal |
Verifiable Integrations
Device Template Library
Ready register maps for energy analysers, reactive relays, generator controllers, chiller panels, water meters and calorimeters. Adding a new model requires no panel work.
Gas Distributor Portal
Where portal access exists, the main-meter reading is pulled straight from the distributor and written as a virtual gas meter — no extra gas meter is needed on site.
Automatic Meter Reading Data
Official meter indexes pulled from the distribution company's automatic reading system are compared against field measurement, so invoice reconciliation rests on two independent sources rather than an estimate.
Market Price and Tariff
For free-consumer sites, hourly market prices and official tariff rows feed the cost calculation. No speculative increase is layered onto future months.
Under What Conditions Does the System Run?
- Measurements are taken every 15 minutes; hourly and daily summaries are produced automatically
- The field unit writes to a local queue first — no record is deleted before the server acknowledges it
- During an internet outage measurements accumulate, then backfill when the link returns and summaries are recalculated
- Every project runs in its own isolated database; cross-project data leakage is prevented architecturally
- Field ↔ server traffic is TLS-encrypted; management commands are signed
- Remote configuration and updates are performed without a site visit
- Every administrative action is written to an audit record
- Screen cost is independent of accumulated data volume — it does not slow down over the years
Which Facility Types Is It Applied To?
Every facility type has its own energy dynamic; measurement points, indicators and alarm thresholds are set accordingly. On the page for your facility type you will find which points are measured and what each indicator tells you: hospital, shopping centre and commercial building, factory and industry, hotel, residential and estate management, solar power plant. For an overview independent of facility type, start with the energy monitoring system page.
