Kabelförbindelse
Anslut RS485-linjerna till ARM_485 terminalblocket på växelriktaren:
- ARM_485_A → D+ (positiv / icke-inverterande)
- ARM_485_B → D– (negativ / inverterande)
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 |
|---|---|---|---|---|
| ARM_485_A (D+) | RS485 A | RS485_POS | RS485 A | TX+ |
| ARM_485_B (D–) | RS485 B | RS485_NEG | RS485 B | TX- |
| GND | RS GND | GND | Not available | G |
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 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.
