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.

SHED_OPT (Mode Shedding, Option)

Controls the way blocks enter mode shedding. Each option listed below has
a companion

No Return

option. The

No Return

shedding options change

the target mode of the device to the shed mode and prevent the device from
re-entering

RCas

or

ROut

mode after the shed condition has ended.

SHED_RCAS (Mode Shedding)

The shed time for the

RCAS_IN

parameter. If the block is in

RCas

mode and

the

RCAS_IN

parameter has not been updated in

SHED_RCAS

time, the

block performs mode shedding as determined by the

SHED_OPT

parameter.

SHED_ROUT (Mode Shedding)

The shed time for the

ROUT_IN

parameter. If the block is in

RCas

mode and

the

ROUT_IN

parameter has not been updated in

SHED_RCAS

time, the

block performs mode shedding as determined by the

SHED_OPT

parameter.

SIMULATE (Option)

Used to bypass the physical I/O channel and allow the block to operate
normally, using a simulated I/O channel. For this feature to be enabled on
an FP-3000, you must set a switch on the back of the device. To see how to
configure the switch, refer to Appendix A,

Configuring the FP-3000
