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 |
|---|---|---|---|---|
| 端子 41 / A- | RS485 A | RS485_POS | RS485 A | TX+ |
| 端子 42 / B+ | RS485 B | RS485_NEG | RS485 B | TX- |
| 端子 43 / GND | RS GND | GND | Not available | G |
配置
检查Carlo Gavazzi计量器是否设置为读取进出口功率。不合适的模式可能导致：
- 缺少馈入读数，或
- 馈入被计算为取用（在“实际取用”之上）
您可以在能量计的“MEASurE”配置菜单中进行设置。此项应设置为“b”。
警告
此设置可能在MID认证的型号中不存在（型号以PFA和PFB结尾）。
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.
