Deze pagina beschrijft de communicatie met een Solis 3T10K via Modbus-RTU (rs485). Standaard staat de omvormer ingesteld op adres 1. Dit kan worden gewijzigd via het display van de omvormer. U vindt de procedure in hoofdstuk 7.3.2 van de handleiding. De RS485-aansluitingen bevinden zich onderaan de omvormer achter een beschermplaat.
Info
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 |
|---|---|---|---|---|
| Pin 3 | RS485 A | RS485_POS | RS485 A | TX+ |
| Pin 4 | RS485 B | RS485_NEG | RS485 B | TX- |
| N/A | RS GND | GND | Not available | G |
Waarschuwing
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.
