Mathematical expressions

Entering formulas using function block format

Formulas can be entered in the schematic using the FUNCTION BLOCK notation. The figure below, for example, represents the way to compute the formula ( 5 + 3 ) * ( 9 + 2) - 7.

LadderWORK ARM software supplies the classical arithmetic functions like ADD, SUB, DIV, MUL and MOD. Moreover the software gives you the possibility to operate with the logical operators like SHR, SHL, ROL, ROR and BIT.

Constant values can be entered using the CONST and IDENT components
