Description
z The format of floating point number of Fatek-PLC follows the IEEE-754 standard. For detail explanation of
the format please refer to 5.3 (Numbering System)…page 5-9.
z When conversion control "EN" = 1 or "EN↑" ( P instruction) has a transition from 0 to 1, will convert the
floating point data from S~S+1 32bits register into D register( integer data ).
z If the value exceeds the valid range of destination, then do not carry out this instruction, and set the
range-error flag “ERR” as 1 and the D register will be intact.
