PM5310
With dual-port Ethernet (Modbus TCP) and RS485 (Modbus RTU) communication, measurement up to the 31st harmonic and 256 KB of data memory, the PowerLogic PM5310 is a strong option for energy monitoring and SCADA systems.

Integration with Argus EMS
The PM5310 connects to Argus EMS over Modbus RTU (RS-485) or Modbus TCP (Ethernet), 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 (RS-485) or Modbus TCP (Ethernet) |
| Connection path | It can join an existing RS-485 line or be read directly over Modbus TCP (port 502) |
| 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.
Because it supports both physical paths, the choice follows the existing infrastructure: if an RS-485 line already runs inside the panel the device joins it, and where the network is ready Ethernet is used directly. On the serial line the polling round grows with the number of devices, while on Ethernet each device needs an IP address and a switch port.
