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 |
|---|---|---|---|---|
| RS485 A1 | RS485 A | RS485_POS | RS485 A | TX+ |
| RS485 B1 | 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.
默认情况下，逆变器的地址设置为1。您可以通过逆变器的设置菜单更改此设置。只有在多个设备连接到RS485通信总线时，这才是必要的。
您可以通过触控控制更改逆变器的地址。操作如下：
| 触控控制 | 影响 |
|---|---|
| 单击一次 | 更改显示或数字 + 1 |
| 单击两次 | 进入或确认 |
| 单击三次 | 上一个菜单 |
| 持续按住5秒 |
|
通过前面或左侧图像所示的“设置通信地址”菜单 更改地址。将地址设置为唯一值。有关更多信息，请参见逆变器手册的第7章。
