12/5/2023 0 Comments Arduino modbus rtu rs485What am i doing wrong, or how can read information out of the (array) register? As i’m assuming i should do that, only didn’t figured out how.įor monitoring i used an TTL to usb converter with labview watching. Only still didn’t got relevant data, i got things like a8/a8 (HEX). ![]() I’ve tried the scenario where the information is 32 bits and not 16 bits. Go to the top bar, and click on: File > Examples > Tools40 > Modbus > and select the ModbusRTUSlave sketch. ![]() Change the B type cable and connect it to the other M-Duino PLC. Only not being able to make some data visible. Once the master is already programmed, we are going to do the same as with the Master PLC, but choosing the ModbusRTUSlave sketch. So i am guessing i do got an connection towards the slave. If not connected TX blinks 10 times, and stops (as programmed). I am trying to receive some data out of an modbus slave, the TX and RX pin on the RS485 are blinking while connected.
