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

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
