Hello everything is fine?
I need to write this Request to obtain the result via serial (Modbus ASCII), but I send it and it always returns blank, I’m doing it exactly like the manual.
Could someone please help me!!
The serial number is available in the register pairs 0x0000/0x0001 (Big Endian) and 0x0100/0x0101 (Little Endian). Reading the serial number in Big Endian format from a probe with slave address 1 using Function Code 03 looks like this: Request: **{:}010300000002FA{cr}{lf}** Response: **{:}0103040002317154{cr}{lf}** Evaluation: Register 0x0000 = 0x0002 Register 0x0001 = 0x3171 Serial number = 0x00023171 = 143729
Find the solution to sending the code!
