Same bits, different meaning

See where a positive DINT becomes negative

signed = unsigned - 232 when bit 31 is on

Signedness changes how a 32-bit pattern is interpreted; it does not change the stored bits. The boundary between 16#7FFF_FFFF and 16#8000_0000 is the fastest way to prove whether a display mismatch is caused by a signed-versus-unsigned contract.

Check the data contract before using the result

  • Confirm whether the source defines a signed DINT, unsigned DWORD or UDINT, or a raw bit mask.
  • Preserve the original hexadecimal value before applying a byte or 16-bit word swap.
  • Treat byte order inside a word and word order across two registers as separate decisions.
  • Test known values around 16#7FFF_FFFF and 16#8000_0000 before changing an HMI, gateway, or PLC mapping.

Interpretation reminder

A converter preserves the 32-bit pattern while changing its representation. Confirm device byte order, word order, signedness, and register mapping before writing values to equipment.

Supporting knowledge-base guides

Start with a public worked example, then use the complete Pro procedure for commissioning and troubleshooting.
