Info
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 | Sofar EMS model OM1 | Sofar EMS model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| Pin 1 / Modbus-485_B | RS485 A | RS485_POS | RS485 A | TX+ |
| Pin 2 / Modbus-485_A | RS485 B | RS485_NEG | RS485 B | TX- |
| Pin 3 / GND_485 | RS GND | GND | Not available | G |
Konfiguration
Varning
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 Sofar EMS will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The Sofar EMS will scan on those first.
Gå till “Main Screen” >> “System Settings” >> “Advanced Function.”
- Modbus SN ska ställas in på ett nummer mellan 1 och 247. Välj inte 0!! Observera att om det finns flera enheter på RS485-bussen, ska varje ha ett unikt nummer. Detta är adressen.
- Slave ska vara markerad.
- Endast när en extra mätare är ansluten direkt till invertern ska “EX_meter For CT” vara markerad. Om det bara finns en mätare parallellt med Sofar EMS ska den inte vara markerad.
- Se till att följande inställningar är korrekta: "Max A Charge", "Max A Discharge", "Grid Charge Ampere"
