If it speaks Modbus, we can probably read it.
Most facilities already own meters capable of far more than they are being asked to do. Before specifying anything new, it is worth finding out what is already installed.
What we integrate most often.
These are the four we work with most. They are not the only meters we can read, if yours publishes a documented register map, send us the model number.
Socomec
Diris A / B / G series, Diris MCM-16 / MCM-48, Digiware, Countis
Full three phase measurement, energy accumulation and power quality on the higher models. The DIRIS MCM multi circuit range is our usual choice for retrofit submetering, up to 48 circuits from one enclosed, revenue grade meter using split core or Rogowski sensors.
Protocols: Modbus TCP, Modbus RTU
Socomec integrationSchneider Electric
PowerLogic PM2000, PM5000, PM8000, ION
Wide range from basic energy meters to revenue grade power quality instruments. Deep register maps that reward reading properly.
Protocols: Modbus TCP, Modbus RTU, Ethernet
Schneider Electric integrationSiemens
SENTRON PAC2200, PAC3200, PAC4200, PAC5100
Frequently already installed in Siemens based plants and, in our experience, often not connected to anything. Straightforward to bring onto the network.
Protocols: Modbus TCP, Modbus RTU, Profinet
Janitza
UMG 96, UMG 103 / 104, UMG 509, UMG 604, UMG 806
German power quality specialists. Detailed harmonic and event analysis on the higher UMG models, plus multi circuit options for branch level metering.
Protocols: Modbus TCP, Modbus RTU, Profibus
How the data actually gets out.
- Modbus TCP, over Ethernet. The most common and the easiest to work with.
- Modbus RTU, over RS-485. Cheap to install, needs care with termination and addressing.
- Profinet, Siemens SENTRON and Janitza meters on a Siemens network.
- Profibus, older Janitza and Siemens estates that have not been migrated.
- Anything else with a register map, if the manual documents the registers, we can almost always read it. Send us the model number.
What usually goes wrong.
- CT ratios entered wrong. The single most common cause of readings that are exactly ten times off.
- RS-485 without termination. Works on the bench, fails intermittently at length.
- Duplicate Modbus addresses. Two devices, one address, confusing results.
- Registers read as the wrong data type. Float versus integer, byte order, and scaling factors buried in the manual.
- Meters installed on the wrong side of a load. Discovered when totals never reconcile.
Answers before you call.
Probably. This list covers the four we work with most, not the limit of what is possible. If a meter publishes a documented Modbus register map, it can almost certainly be integrated. Send us the model number and we will tell you.
No. Mixed estates are normal, and a monitoring system should not care. We frequently read several different brands into one historian, and once the data is in, the dashboards look identical.
Many meters have an RS-485 port that has simply never been wired. A Modbus RTU daisy chain to a gateway is often the cheapest way to bring existing meters online without replacing anything.
We can supply them. We are not tied to any one manufacturer and we will specify whatever suits the job, but we do have a partnership with a Socomec distributor, so where Socomec is the right fit, the meters, the current sensors and the system that reads them can come on one quote instead of you sourcing hardware separately. None of that changes the advice: where you already have capable meters installed, we will tell you so rather than quoting replacements.
If you are billing tenants, use a meter with the appropriate accuracy class and check your local requirements, since rules vary by jurisdiction. We will point you at the right class of instrument for what you are trying to do.
