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
Advarsel
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 til "Main Screen" >> "System Settings" >> "Advanced Function."
- Modbus SN skal sættes til et tal mellem 1 og 247. Vælg ikke 0!! Bemærk, at hvis der er flere enheder på RS485-bussen, skal hver tildeles et unikt nummer. Dette er adressen.
- Slave skal være markeret.
- Kun når en ekstra måler er tilsluttet direkte til inverteren, skal "EX_meter For CT" markeres. Hvis der kun er en måler parallelt med Sofar EMS, skal det være afmarkeret.
- Sørg for, at følgende indstillinger er korrekte: "Max A Charge", "Max A Discharge", "Grid Charge Ampere"
