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.
Its configurable.
I set the address with 15000 but still modbus timeout. Can you take the picture the sample setting ?
