PM5110
The PowerLogic PM5110 is the standard professional choice for factory panels and energy monitoring projects. Measurement up to the 15th harmonic, 33 configurable alarms and one digital output make integration into industrial automation systems easy.

Integration with Argus EMS
The PM5110 connects to Argus EMS over Modbus RTU over an RS-485 serial line, and because a ready register template ships with the platform you do not have to work out a point map on site. The field agent polls the device every 60 seconds by default, writes the reading into a local queue first and then forwards it to the server over MQTT/TLS; nothing is deleted before the server acknowledges it. Hourly and daily summaries are derived from these raw readings, and the consumption and cost screens are fed from the same series.
| Protocol | Modbus RTU over an RS-485 serial line |
| Connection path | The RS-485 line lands on a Modbus TCP gateway or on the field PC serial port |
| Default polling period | 60 seconds (field agent) |
| Points in the ready template | 43 registers |
| Consumption calculation | Difference of the kWh import index over the period (MAX − MIN) |
| Data assurance | Local queue plus server acknowledgement; nothing is deleted before it is confirmed |
When Is This Model the Right Choice?
It is built for main distribution boards and critical loads: alongside energy and demand, the basic power quality quantities are reported too. Reactive penalty tracking and compensation assessment become reliable from this level upwards.
The device has a serial output, so it joins the existing RS-485 line instead of requiring a dedicated Ethernet run into the panel. The more devices share one line, the longer a polling round takes, which is why the field agent reads each line sequentially and waits 60 ms between devices by default. A slave ID collision and a missing line termination are the two most common commissioning mistakes.
