ROUT_IN (Mode Shedding, Process)
The cascade input set by a remote host. This is propagated to the output of
the block when it is in
ROut mode. If the block is in ROut mode and this
parameter is not updated in SHED_ROUT time (a parameter in the resource
block), the block enters mode shedding. Mode shedding allows the block
to degrade from
ROut mode into some higher priority mode.
ROUT_OUT (Process)
This is the back calculation output used by the host when trying to establish
a remote output loop. While the loop is being established, it is the current
value of the output channel and can be used by the host to initialize for
smooth transfer of control.
RS_STATE (Diagnostic, Process)
The current state of the device.
SEL_1 through SEL_3 (Process, Scaling, Tuning)
Input values for the selector.
SEL_TYPE (Scaling)
Defines the selector action—High, Medium, or Low.
SET_FSTATE (Faultstate, Option)
Allows the user to set the device faultstate to active. This, in turn, forces all
output blocks into their own faultstate behavior.
