Native Modbus registers

The 16 Bit Modbus registers can be displayed in 4 different modes.

  • Signed
  • Unsigned
  • Hex
  • Binary

32 bit signed integer

This combines 2 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • 32 Bit signed Big-endian
  • 32 Bit signed Little-endian
  • 32 Bit signed Big-endian byte swap
  • 32 Bit signed Little-endian byte swap

Example:
Byte Order: Big-endian
The decimal number 123456789 or in hexadecimal 07 5B CD 15.
Order as they come over the wire in a Modbus message: 07 5B CD 15

32 bit unsigned integer

This combines 2 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • 32 Bit unsigned Big-endian
  • 32 Bit unsigned Little-endian
  • 32 Bit unsigned Big-endian byte swap
  • 32 Bit unsigned Little-endian byte swap

Example:
Byte Order: Big-endian
The decimal number 123456789 or in hexadecimal 07 5B CD 15.
Order as they come over the wire in a Modbus message: 07 5B CD 15

64 bit signed integer

This combines 4 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • 64 Bit signed Big-endian
  • 64 Bit signed Little-endian
  • 64 Bit signed Big-endian byte swap
  • 64 Bit signed Little-endian byte swap

Example:
Byte Order: Big-endian
The decimal number -1,234,567,890,123,456,789 or in hexadecimal EE DD EF 0B 82 16 7E EB.
Order as they come over the wire in a Modbus message: EE DD EF 0B 82 16 7E EB

64 bit unsigned integer

This combines 4 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • 64 Bit unsigned Big-endian

  • 64 Bit unsigned Little-endian byte swap

Example:
Byte Order: Big-endian
The decimal number 1,234,567,890,123,456,789 or in hexadecimal 11 22 10 F4 7D E9 81 15.
Order as they come over the wire in a Modbus message: 11 22 10 F4 7D E9 81 15

32 bit floating

This combines 2 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • Float Big-endian
  • Float Little-endian

Example:
Byte Order: Big-endian
The floating point number 123456.00 or in hexadecimal 47 F1 20 00.
Order as they come over the wire in a Modbus message: 47 F1 20 00

64 bit double

This combines 4 16 Bit Modbus registers. It can be displayed in 4 different word/byte orders.

  • Double Big-endian
  • Double Little-endian
  • Double Big-endian byte swap

Example:
Byte Order: Big-endian
The floating point number 123456789.00 or in hexadecimal 41 9D 6F 34 54 00 00 00.
Order as they come over the wire in a Modbus message: 41 9D 6F 34 54 00 00 00
