Siemens SENTRON PAC3220

Name: Siemens SENTRON PAC3220
Brand: Siemens
SKU: e0deb75f-dc73-42b6-8df5-5590159c97ea

Power monitor for distribution boards: voltage, current, power, energy per tariff and power quality.

The Siemens SENTRON PAC3220 is a power monitoring device that measures voltage, current, power, energy and power quality in low-voltage distribution boards. This Modbus TCP template reads all live values, demand values and energy counters, and lets you set transformer ratios, limits and outputs from ModbusCloud.

Protocol: Modbus TCP
Connection: Ethernet, Modbus TCP
Registers: 918, read and write

Brand: Siemens
Key readings: Voltage L-N and L-L · Current per phase and neutral · Active power · Reactive and apparent power · Power factor · Frequency · Active energy import and export · THD voltage and current
Available commands: Current transformer ratio · Voltage transformer ratio · Limit values · Digital output functions · Energy counter reset · Tariff switchover

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 and power per phase of a distribution board on a ModbusCloud dashboard.
Send an email alert when the current on one phase or the neutral current passes a threshold.
Compare daily active energy per tariff in the history to find standby consumption at night.
Watch THD and voltage unbalance over a year to spot power quality problems early.
Correct the current transformer ratio remotely after a transformer swap on site.

Installation

Connect the Ethernet port of the PAC3220 to the same network as the ModbusCloud Gateway, or to the LAN port of the Gateway.
On the meter, open the communication settings, switch DHCP off and set a fixed IP address and subnet. Leave the Modbus port at 502.
In ModbusCloud, add a Modbus TCP device with the IP address of the meter, port 502 and unit ID 1, and import this template.
Check that voltage L1-N and frequency show plausible values. If they stay empty, check the IP address and whether the Modbus port is 0.
Before you write settings, check that password protection for communication and the hardware write protection are off on the meter.

Things to watch for

The Gateway cannot reach the meter. What should I check?

Check that the meter and the Gateway are in the same subnet and that the IP address on the display matches the one in ModbusCloud. A Modbus port of 0 switches the Modbus TCP server off. With the IP filter on, only write commands from the own subnet are accepted.

Why does the export energy counter show no unit?

The export and reactive import counters are read as plain numbers. Compare the value with the energy menu on the display to see in which unit the meter counts, and set the unit of the register in ModbusCloud if you need it on a dashboard.

My write to a setting is refused. Why?

The meter rejects writes while password protection for communication or the hardware write protection is active. Switch both off on the device, then write again. Read the register first so you know the current value, and change one setting at a time.

Can I read several PAC meters through one Gateway?

Yes. Give each meter its own fixed IP address and add each one as its own Modbus TCP device in ModbusCloud with this template. PAC3120 meters on RS485 each need a unique Modbus address on the bus.

Why are the history values zero right after installation?

The daily and monthly energy history fills up over time. Days and months before the meter was installed, or before its clock was set, stay at zero. Set the date and time on the meter so the history timestamps are correct.
