RS485 MODBUS WIRING DIAGRAM

Energy Meter EM24 RS485 manual [Victron Energy]
Sep 07, 2020The diagram shows the wiring when used as a grid meter. To measure a single phase PV inverter in a 3-phase system, connect all 3 phases to the grid phasing terminals (3, 6 and 9). 2 meters wired on to one RS485-USB converter. In this case the modbus address of the additional meter needs to be changed, so each is unique. See chapter 6.
RS485 - RS485 Cables – Why you need 3 wires for 2 (two) wire RS485
RS485 needs 3 conductors and a shield people say it's a two-wire network but it is not. Two conductors are used to carry the RS485 Differential voltage signal. The Shield is connected to earth/ground at one end only and provides shielding against induced noise.[PDF]
Installation Guide Energy Meter with Modbus Connection
Gateway over an RS485 connection. Refer to the connection diagram below. If you are connecting two meters, refer to Installing Two Meters on page 57. Figure 8: Meter connections NOTE Clamp the CT connected to L1 CT around the wire connected to ØL1. Clamp the CT connected to L2 CT around the wire connected to ØL2.[PDF]

Energy Meter ET340 manual [Victron Energy]
Mar 20, 2021To connect multiple Energy Meters, wire each meter to a separate RS485-USB converter. Which are then each plugged into a separate USB socket on the GX device. Connecting multiple ET340 meters to the same RS485-USB cable is not possible: the ET340 meter has no display and its Modbus address can therefor not be changed.

How to interface Arduino, esp8266 or esp32 to RS-485
May 11, 2020RS-485 work as a broadcast, when you sent a message all device connected to the wire receive that, and so peoples to use It better implements a lot of protocol to send message to a specified device or to a broadcast address. In this article we use a normal communication from two device in very simpl
What is Serial Communication and How it works? [Explained]
Nov 25, 2018RS-232 Wiring Connection. The RS232 serial port has nine pins, male or female type models. RS 232C serial communication interface is the later version of RS232. All the features present in RS232 is present in the RS232C model except it has 25 pins. Out of 25 or 9 pins, we use only three pins for the connection of terminal devices.
