SHED_RCAS

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

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

The simulate parameter is 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, you must set a switch on the back of the FP-3000. To

see how to configure the switch, refer to AppendixA, Configuring the

FP-3000.

SP_HI_LIM

The upper limit on the setpoint of the block. If the setpoint exceeds this

value, the setpoint is considered to be SP_HI_LIM with a status that

indicates that it is limited.

SP_LO_LIM

The lower limit on the setpoint of the block. If the setpoint is below this

value, the setpoint is considered to be SP_LO_LIM with a status that

indicates that it is limited.

Table C-14. Shed Conditions

Shed Mode Behavior

Normal Shed The block sheds into the next higher priority

mode set in the permitted mode field of

MODE_BLK.

Shed to Auto The block sheds into automatic mode.

Shed to Manual The block sheds into manual mode.

Shed to Retained The block sheds to the next higher priority mode

set in the target mode field of MODE_BLK.
