Function - Calculates the logarithm (base 10) of the input.
IN : REAL Real value
Q : REAL Result: logarithm (base 10) of IN
In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung. In IL, the input must be loaded in the current result before calling the function.
Q := LOG (IN);
(* The function is executed only if EN is
(* ENO keeps the same value as EN *)
Op1: LD IN
ST Q (* Q is: LOG (IN) *)
