Cablaggio RS485 della serie LD di Autarco | SmartgridOne Documentation

Questa pagina descrive la comunicazione con un inverter ibrido Autarco della serie LD tramite Modbus-RTU (rs485). Per impostazione predefinita, all'inverter è assegnato l'indirizzo 1. L'interfaccia RS485 è un connettore a 4 pin situato nella parte inferiore dell'inverter, dietro una piastra protettiva. La posizione esatta è contrassegnata dal riquadro arancione nell'immagine seguente:

Osservando più da vicino, la porta si presenta così:

Per questo connettore a 4 pin dell'inverter Autarco è necessario utilizzare un connettore appropriato per il collegamento al SmartgridOne Controller. Sul SmartgridOne Controller, l'inverter può essere collegato alla porta RS485. Il cablaggio è il seguente:

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

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.
