Loading registers…

Send your device list

If a device is not in the library yet, we build the template for free as soon as we have the register data.

Use cases

Show voltage, current, power and power factor per phase on a dashboard for each switchboard.
Log imported and exported energy per phase to compare tenants or production lines month by month.
Get an alert when the current unbalance or voltage THD passes a limit you set.
Watch the demand values to see when a connection gets close to its contracted capacity.
Switch a relay output of an AXM module from ModbusCloud, for example to shed a load.

Installation

Connect the RS485 terminals A and B of the meter to the RS485 port of the ModbusCloud Gateway, with a 120 ohm terminator at both ends of the bus.
On the meter, set the address, baud rate and parity in the communication menu, for example address 1, 19200 baud, no parity.
Set Basic Parameter Mode to Primary if you want readings that match the display, independent of the CT and PT ratio.
In ModbusCloud, add a Modbus device with the same address and settings and import this template.
Check that frequency reads about 50 Hz and the phase voltages match the display of the meter.

Things to watch for

The meter does not answer on the bus. What should I check?

Compare address, baud rate and parity with the communication menu of the meter. Parity setting Non1 means no parity with one stop bit, Non2 means no parity with two. Then swap A and B and make sure the bus has a terminator at both ends.

Why are currents and power much lower than on the display?

The meter is in Secondary mode, so values are on the secondary side of the CT and PT. Set Basic Parameter Mode to Primary, or multiply by CT1/CT2 and PT1/PT2. The integer registers always need that ratio.

The energy counter is ten or a thousand times off. Why?

The energy registers follow Energy Display Mode. In Primary mode the counter has one decimal, in Secondary mode three. Check the setting on the meter and keep it the same as when you set up the template.

Can I write the settings and relays from ModbusCloud?

Yes. Settings, clock and energy presets are holding registers written with function code 16, relay outputs are coils. A write to the clear and restore registers resets counters or the whole meter, so check the value before you send it. Writing must be enabled for the gateway first.

Can I connect several meters to one RS485 line?

Yes. Give each meter its own address and the same baud rate and parity. Wire them as a line, not a star, and terminate both ends.
