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.
Note 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 the FP-3000 manual.
SIMULATE_D (Option)
Used to bypass the physical I/O channel and allow the block to operate
normally, using a simulated discrete I/O channel.
