Hello, I want to use the modbus rtu protocol on our designed linux board-imx8mp Soc, so I need to enable the rs485 line in half-duplex. I have a few
Connection First, use an RS485-to-RS232 converter or RS485-to-Modbus/TCP converter as a conversion medium between the computer and RMS-MODBUS01B card, and connect the converter to the RJ45 port based on the following wiring diagram. Figure 3-1 Connecting the Modbus card to the converter Th...

In this article, we have learned how to use Java to implement RS485 modbus communication. We have explored the steps to set up the RXTX library, establish modbus communication, and process the response. We have also provided a sequence diagram and a state diagram to illustrate the communication...
1.3.3 Cable Connection(02355639) Step 1 Set a hardware address for the Modbus card. The hardware address is set over S2 (RS485 address DIP switch) shown in Figure 1-1. As shown in Figure 1-2, the address contains eight digits. If a toggle switch is...
The communication will take place using the RS485 standard. STM32 is connected to the RS485 to TTL converter and the computer is connected via the RS485 to USB converter.This is it for the connection, let’s see the code now.The Slave Software...
