Selects the logic equation (1 to 8) to be configured.
See Appendix A, page 116 for description of sources.
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.
Selects the Operator type: OR, AND, NOR, NAND, EXOR, END.
Select END if no more elements are required.
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.
