Okablowanie Autarco LH-series RS485 | Sofar EMS Documentation

Ta strona opisuje komunikację z hybrydowym falownikiem serii Autarco LH za pomocą Modbus-RTU (rs485).
Domyślnie falownik jest ustawiony na adres 1. Interfejs RS485 to złącze 4-pinowe o nazwie "COM" znajdujące się na dole falownika
za osłoną ochronną. Dokładną lokalizację zaznaczono na pomarańczowym polu na poniższym obrazku:

Zbliżenie portu wygląda następująco:

Do tego 4-pinowego złącza na falowniku Autarco należy użyć odpowiedniego złącza, aby podłączyć do Sofar EMS.
Na Sofar EMS falownik może być podłączony do portu RS485. Okablowanie jest następujące:

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	Sofar EMS model OM1	Sofar EMS 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 Sofar EMS will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The Sofar EMS will scan on those first.
