Hallo guys, I need your advice. I already tried modbus communication, but not succed, on the software alarm appear" Modbus communication timeout". I already setted longer time but error still appear.
Check the devices address
Modbus will try for few seconds to establish the communication.
After this time, if communication not happens for any reason then it will show timeout error message. Its a common error so there may be any type of reason behind it.
Check Communication and all configurations again.
Also check cables/converters.
Ok Vignesh, In software modbus setting there are modbus format, little endian & big endian. Do you know the meaning?
You know addressing memory for analog input is in range 30000-39999 but in manual flowmeter the address that I want retrieve the data is 15000. Can we convert this address into 30000-39999 range?
Yes, map the same address at both sides.
I set the address with 15000 but still modbus timeout. Can you take the picture the sample setting ?
