RS485
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 |
|---|---|---|---|---|
| +T/R | RS485 A | RS485_POS | RS485 A | TX+ |
| -T/R | RS485 B | RS485_NEG | RS485 B | TX- |
| RTN | RS GND | GND | Not available | G |
配置
与逆变器的通信可以通过以太网或 RS485 进行。按照 产品手册 中的描述设置逆变器。
如果选择通过 RS485 工作，请注意以下事项：
- SmartgridOne Controller 通过 RS485 支持的协议是 "Modbus Sunspec" 和 "Aurora." 在 SmartgridOne Controller 中，它们分别被称为 "Modbus RTU Sunspec 协议" 和 "ABB Aurora Power One 协议"。
- "Modbus Sunspec" 仅支持在逆变器连接的 RS485-2。
- 默认情况下，系统首先以 9600 波特率和无奇偶校验扫描设备。建议将逆变器设置为此波特率和奇偶校验。
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.
如果选择通过以太网工作，请注意以下事项：
- 逆变器作为从设备/服务器，SmartgridOne Controller 作为主设备/客户端。
- 通过以太网，仅支持 "Modbus Sunspec" 协议。您必须配置 SmartgridOne Controller 以使用此协议。
- 逆变器和 SmartgridOne Controller 必须连接到同一局域网。
