Control and Data Input/Output Interfaces
GPI Interface
Two independent ground-closure sensing GPI inputs (
GPI 1
and
GPI 2
; each
sharing common ground connection as chassis potential) are available.
Associated with each GPI user control is a selection of one of 32 user-defined
card presets in which GPI activation invokes a card control preset. Because
the GPI closure invokes a user-defined preset, the resulting setup is highly
flexible and totally user-defined. Invoking a user preset to effect a change
involves card setup communication limited only to the items being changed.
GPI triggering can be user selected to consider the activity on discrete GPI
ports, or combinations of logic states considering both GPI inputs, as well as
be set for level or edge triggering. This flexibility allows multistage,
progressive actions to be invoked if desired. Indication is provided showing
whenever a GPI input has been invoked.
GPO Interface
Two independent phototransistor non-referenced (floating) contact pairs
(
GPO 1/1
and
GPO 2/2
) are available. A GPO can be invoked by setting a GPO
to be enabled when a card preset is in turn applied (i.e., when a preset is
invoked (either manually or via event-based loading), the GPO is
correspondingly also activated.
