PM5560
The PowerLogic PM5560 offers advanced power quality monitoring, comprehensive communication and extended I/O options at critical load points. It is the preferred meter in data centres, hospitals and large industrial facilities.

Integration with Argus EMS
The PM5560 connects to Argus EMS over Modbus TCP over 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 TCP over Ethernet |
| Connection path | Directly over Modbus TCP (port 502) — no separate gateway is needed |
| 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 extends the professional measurement set and is preferred for main incomers, transformer outgoers and large mechanical loads. Energy, demand, power factor and harmonic indicators come from a single device, so no separate analyser is needed inside the panel.
The device serves Modbus TCP directly over Ethernet, so no gateway is needed. In exchange, each device needs an IP address on the network and a switch port inside the panel. If more than one master polls the same device at once — a building automation system alongside Argus EMS, for example — its concurrent connection limit has to be respected.
