Schneider-Electric PM 5000 Series Energy Meters
Supported Devices
The PM 5000 series covers a wide range of meters. Capabilities vary by specific model number (e.g., PM51xx are generally RS485 only, while PM5320/PM5340 include Ethernet).
| Device Type | Modbus TCP (Ethernet) | RS485 |

| Schneider-Electric PM 5100 / 5110 / 5111 | ❌ | ✅ |
| Schneider-Electric PM 5310 / 5330 / 5331 | ||
| Schneider-Electric PM 5320 / 5340 / 5341 | ✅ |
pm5300
Wiring
Ethernet
Applicable only to PM5320, PM5340, and PM5341. For correct ethernet wiring: Follow the guidelines for ethernet wiring.
RS485
The RS485 terminals are located on the bottom of the device (connector 6 in the diagram below).
RS485 Wiring
- For correct RS485 wiring: Follow the guidelines for RS485 wiring.
- If the wiring shown in the table below is incorrect, please let us know.
- There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.
| Device | a-TroniX Controller model OM1 | a-TroniX Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| Terminal 22 / D1 (+) | RS485 A | RS485_POS | RS485 A | TX+ |
| Terminal 23 / D0 (-) | RS485 B | RS485_NEG | RS485 B | TX- |
| Terminal 25 / 0V | RS GND | GND | Not available | G |
Note
Shielding: The shield wire should be connected to Terminal 24 (SHLD). Note that the ground terminal is not available on the meter itself; the shield should be connected to ground at the other end of the bus[cite: 246, 1627].
Configuration
Ethernet
Applicable only to PM5320, PM5340, and PM5341. To configure the IP address:
- Navigate to Maint > Setup > Comm > Enet.
- Configure the IP Address, Subnet Mask, and Gateway.
- Ensure the Modbus TCP protocol is enabled (usually Port 502).
RS485
NOTE: RS485 Device Addresses
- You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
- Use lower addresses first (1, 2, ...) because the a-TroniX Controller will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The a-TroniX Controller will scan on those first.
To configure the Serial settings (Baud rate, Parity, ID):
- Navigate to Maint > Setup > Comm > Ser.
- Edit the Address (Unit ID), Baud rate, and Parity to match your gateway settings.
