Macro logic
Macro logic provides a powerful tool for activating (or deactivating) events
controlled by programmed conditions. The programmed conditions are logic
equations combining the macro inputs (macro events) and timed or latched
output conditions.
Up to 48 macros can be defined for the door controller.
Macro events are used as the macro logic program’s inputs. Up to four macro
inputs may be included in the logic equation. Each macro input in the logic
equation can be programmed as an AND or an OR function and may be inverted
to formulate NAND and NOR equations.
Options are provided so that the macro result will trigger a macro output (event),
which may be a pulse, timed, on delay, off delay or latched when activated. The
output event can be inverted.
Macro logic is programmed in “Expander > Macro logic tab” described on page
89.
