The floating point (real) numbers used by the S7 system are in the industry standard IEEE754 format. You have a sign bit, and 8-bit exponent part and a 23-bit factional part. The following link might prove useful. Floating point number representation info If you want to try some convertions and find out what hex representations match particuler floating point numbers, the following site has some convertors (to go from real to hex or hex to real). Floating point convertors Hope this is of help to you. |
