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 | DemoBrandName ControllerDemoName model OM1 | DemoBrandName ControllerDemoName 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 DemoBrandName ControllerDemoName will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The DemoBrandName ControllerDemoName will scan on those first.
前往“主屏幕” >> “系统设置” >> “高级功能。”
- Modbus SN 应设置为 1 到 247 之间的任意数字。不要选择 0！！请注意，如果 RS485 总线上有多个设备，每个设备应 给予一个唯一的编号。这就是地址。
- 应勾选从设备。
- 只有在附加计量器直接连接到逆变器时，才应勾选“EX_meter For CT”。如果只有一个与 DemoBrandName ControllerDemoName 并联的计量器，则应取消勾选。
- 确保以下设置都正确：“充电最大电流”，“放电最大电流”，“电网充电安培”
