Ethernet
För korrekt ethernetkablage: Följ riktlinjerna för ethernetkablage.
RS485
Anslut RS485-kablarna till kommunikationsporten på Solis-enheten (växelriktare eller Export Power Manager).
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 | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| A | RS485 A | RS485_POS | RS485 A | TX+ |
| B | RS485 B | RS485_NEG | RS485 B | TX- |
| GND (valfritt) | RS GND | GND | Not available | G |
Konfiguration
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 SmartgridOne 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 SmartgridOne Controller will scan on those first.
Se till att enheten är konfigurerad med följande Modbus-inställningar för att matcha drivrutinens specifikationer:
- Baudrate: 9600
- Data bits: 8
- Stop bits: 1
- Parity: Ingen
- Modbus-adress: 1 (standard) - Omfång: 1 till 254
