Variable
: Value
Meaning
: Calculated 32-bit DINT load value in unit [1], with sign
Variable
: Value (Real)
Meaning
: Calculated 32-bit fixed point REAL load value with mantissa and exponent in unit [1]
The format matches the REAL format of IEC 61131-3, which in turn is based on the REAL format of IEC 559.
A REAL number (single precision) is defined as follows (See also Beckhoff InfoSys:
). In accordance with IEC 61131 this 32-bit variable can be directly linked with a FLOAT
variable of the PLC.
