CHoPAN supports two data types in the Sedona Framework client:
Boolean (two-state) — Chopan Boolean Point or Boolean Writable (ChopBoolPt, ChopBoolWr).
Float (numeric) — Chopan Float Point or Float Writable (ChopFltPt, ChopFltWr)
When making Chopan client points in the Chopan Point Manager, discovery makes available only those properties (slots) that are compatible with these two data types.
If discovering data items in a Sedona Framework device’s app, selectable slots for Float points include those with data types float
, long
, double
, short
, and int
(eger). Only slots of type bool
are selectable for Boolean points. Other component slots using other data types, e.g. Buf
(string
), as well as actions, are shown “ghosted”—that is they are unavailable.
If discovering data items in the JACE’s station, only components with selectable properties appear—components based on incompatible data types, such as statusString, statusEnum,
string, etc., do not display. Selectable properties for Float points include data types statusNumeric
, float
, double
, short
, and integer
. Selectable properties for Boolean points are statusBoolean
and boolean
.
Regardless of target, the “out” slot of a Chopan point in the device’s app is either a float (ChoFltPt, ChoFltWr) or a bool (ChoBoolPt, ChoBoolWr).
The NiagaraAX Chopan client, which is largely Sedona proxy points that use an assigned tuning policy based on the “Chopan”
Comm Type, can also process string type data. The JACE platform provides a much larger code space for this type of support than a typical Jennic-based device.
