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 |
|---|---|---|---|---|
| 引脚 1 / Modbus-485_B | RS485 A | RS485_POS | RS485 A | TX+ |
| 引脚 2 / Modbus-485_A | RS485 B | RS485_NEG | RS485 B | TX- |
| 引脚 3 / GND_485 | RS GND | GND | Not available | G |
配置
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.

- Modbus SN 应设置为 1 到 247 之间的任何数字。请不要选择 0！！请注意，如果 RS485 总线上有多个设备，则每个设备应具有唯一的编号。这是地址。
- 应检查从设备。
- 只有在额外的计量仪器直接连接到逆变器时，才应勾选 “EX_meter For CT”。如果只有一个表与 SmartgridOne Controller 并联，应该取消勾选。
- 确保以下设置均正确： “最大充电电流”，“最大放电电流”，“电网充电安培”
