RS_STATE
State of the function block application state machine.
SEL_1
First input value to the selector.
SEL_2
Second input value to the selector.
SEL_3
Third input value to the selector.
SEL_TYPE
This parameter specifies the type of selector action, from choices of High, Medium, and Low.
SET_FSTATE
Allows the Fault State condition to be manually initiated by selecting Set.
SHED_OPT
Defines action to be taken on remote control device timeout.
SHED_RCAS
Time duration at which to give up on computer writes to function block RCas locations. Shed from
RCas shall never happen when SHED_RCAS = 0.
SHED_ROUT
Time duration at which to give up on computer writes to function block ROut locations. Shed from
Rout shall never happen when SHED_ROUT = 0.
SIMULATE
Allows the transducer analog input or output to the block to be manually supplied when simulate is
enabled. When simulation is disabled, the simulate value and status track the actual value and status.
SIMULATE_D
Allows the transducer discrete input or output to the block to be manually supplied when simulate is
enabled. When simulation is disabled, the simulate value and status track the actual value and status.
SP
The analog setpoint of this block.
SP_D
The discrete setpoint of this block.
SP_HI_LIM
The setpoint high limit is the highest setpoint operator entry that can be used for the block.
SP_LO_LIM
The setpoint low limit is the lowest setpoint operator entry that can be used for the block.
SP_RATE_DN
Ramp rate at which downward setpoint changes are acted on in Auto mode, in PV units per second.
If the ramp rate is set to zero, then the setpoint will be used immediately. For control blocks, rate
limiting will apply only in Auto. For output blocks, rate limiting will apply in Auto, Cas, and RCas
modes.
