Can I use this program with arduino nano or not. Because When I use this program with my arduino nano then it won't work. So please tell me solution to how I do that.
Hello bro i want the Communication of arduino with fatek plc, having arduino as slave, do you have any idea, if any then please make a video on it or give me the necessary information here. Thanks in advance
Hello , i have problem when sending data . I press Send button but i do not receive any response in the Response tab , so i am not sending any data . Any idea ? I checked pin connections ..
Please do video without using modbus software. Do it same communication with any real devices like temperature controller. How to get values and how to read valves in arduino
Your explanation is good but not working for me. I am checking everything like com port,bread board connection etc but nothing happened. Please suggest...
@@Circuitdigest i am not using lcd screen and servo and code is exactly same but when i will sending 1 from simply modbus master software nothing happened. No response from led neither pin no2 or pin no 5.
@@Circuitdigest yes, i am not only seeing your video. But also going to website and follow step by step. I am suspected that my rs 485 to usb converter not working (but sensing com port 9 in computer). Is it a possiable reason what do you think??
Nice video. I have a question, can you demonstrate the reading as well?
if we use RE/DE pins individual node.begin(1,1,?); ?
hallo, your video is usefull but i have a problem. i want to send data from slave (arduino) to master. but i don't know that syntax. can you help me?
Can i read data in a Elevator system's MODbus or Canbus so that i can find out the floor number shown in the display using arduino? Please help

Make sure you have selected the correct COM port and set the COM port settings as mentioned in the post.
excellent Simply Modbus description video: i think this example translates " 01 10 00 00 00 03 06 00 01 00 00 00 6A DB 37" to >>>
DeviceID; FunctionOpcode; StartAdress; Count; CrcLow; CrcHigh
this RTU: 01 = slaveID, 10 = FC, 00 00 = HiLowStartAddress, 00 03 = NumOfRegisters, 06 = ByCount?, 00 01 = L1on, 00 00 = L2off, 00 B4 = 180motor, DB = CrcL, 37 = CrcH
I'm not receiving Response what should I do
Useful video 👍
hello sir, if i want to use tx / rx from softwareserial, is it possible?
i can't send data from arduino from serial monitor to change SV for Slave address 2. Can you help me, how do i solve it?
Simply modbus write doesn't work when I press send button..plz help

did you find the solution?? please help
please share the library
Hi sir i want to download your Arduino software how to i do it ,
Many Thanks,

Very well done. Excellent job.
Hello, its posible use softwareserial with modbusrtu library i want to use serialprint, can u help me?
please post your question on our forums circuitdigest.com/forums. I am sure someone there will be able to help you with this
@@Circuitdigest thx so much
Sir I'm unable to send data what should I do
You can try posting your problem in detail on our forums. circuitdigest.com/forums The author will respond to you there
do you know the solution?? please help
@@sonateresa check if RE and DE pins are connected together .

@@Circuitdigest pls reply
Are you sure you are sending the whole data frame correctly?
