Binary output status read (code 2) - Function allows, with one message, to read many subsequent
addressed binary output statuses. The attempt to read an non-existing binary input leads to error message
Example: 1-5 output read

Memory Register read (code 3) – the Function allows, with one message, to read subsequently
addressed registers . An attempt to read a non-existing register leads to an error message.
Example: 108-110 register read
Request Response

Function Code 0x03 Function Code 0x03
Register address – high part 0x00 Bytes 0x06
Register address – low part 0x6B Register value – high part (108) 0x02
Number of registers – high part 0x00 Register value – low part (108) 0x2B
Number of registers – low part 0x03 Register value – high part (109) 0x00
Register value – low part (109) 0x00
Register value – high part (110) 0x00
Register value – low part (110) 0x64
