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 (引脚 22) | RS485 A | RS485_POS | RS485 A | TX+ |
| B (引脚 23) | RS485 B | RS485_NEG | RS485 B | TX- |
| 不适用 | 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.
有关更改 Modbus 地址的更详细信息，请参阅仪表手册。 默认情况下，仪表设置为地址 1。可以通过仪表显示更改。
- 使用按钮进入程序模式 2。
- 按住右侧按钮 3 秒以打开菜单。
- 滚动到 LCD 页面 Modbus/M-bus ID (addr xxx)。
- 按住右侧按钮 5 秒以进入编程模式。
- 值开始闪烁：选择 3 位数字 (Modbus: 001-247)。按住两个按钮 3 秒确认每一位数字。
- 当设置确认时，LCD 显示 OK。
