…Functions / Logic Equations
Equation Number Selects the logic equation (1 to 8) to be configured.
Operand 1 (8) See Appendix A, page 116 for description of sources.
Invert 1 (8) Logically inverts (applies NOT function to) the digital signal.
For example, if the digital signal assigned to the operand has a state of '1' it is inverted to a state
of '0' before being applied to the equation.
Operator1 (7) Selects the Operator type: OR, AND, NOR, NAND, EXOR, END.
Select END if no more elements are required.
Math Blocks Up to 8 math blocks can be configured. Each block can be configured as one of 6 different
types (see Block Type below). The resulting analog value can be used as a source for other
function blocks, for example, Process Variable in the control block – see Custom Config., page
38.
Math Block Number The math block number (1 to 8).
Block Type Selects the type of math block required.
