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 | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
|---|---|---|---|---|
| A (pin 22) | RS485 A | RS485_POS | RS485 A | TX+ |
| B (pin 23) | RS485 B | RS485_NEG | RS485 B | TX- |
| N/A | 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 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 i målerens manual for mere detaljerede oplysninger om ændring af Modbus-adressen. Som standard er måleren sat til adresse 1. Dette kan ændres via målerens display.
- Brug knapperne til at gå til Programtilstand 2.
- Tryk og hold den højre knap i 3 sekunder for at åbne menuen.
- Rul til LCD-siden Modbus/M-bus ID (addr xxx).
- Tryk og hold den højre knap i 5 sekunder for at gå ind i programmeringstilstand.
- Værdien begynder at blinke: vælg 3 cifre (Modbus: 001-247). Bekræft hvert ciffer ved at holde begge knapper nede i 3 sekunder.
- LCD'en viser OK, når indstillingen er bekræftet.
