L_TYPE
The linearization type. This parameter affects the way the value from the
transducer is linearized in the analog input block before it is presented as
the block output. In all cases, the
FIELD_VAL parameter behaves as
follows:
Table C-7.
Operation Bitmasks
Bitmask Description
Invert In discrete blocks, this maps a physical state of
Discret_State_0 to Discret_State_1 and maps every
other physical transducer state to
Discret_State_0.
SP-PV Track in Man Forces the setpoint to track the process variable in ROut.
SP-PV Track in LO or IMan Forces the setpoint to track the process variable in LO or IMan.
SP Track Retained Target Forces the setpoint to track the input value of the retained
target of the block. The retained target of the block is the
lowest priority mode set in the target mode field of the
MODE_BLK parameter of the block. For example, if the RCas
bit is set in the target mode, the setpoint tracks
RCAS_IN. For
a list of modes in priority order, see Table 4-6 in Chapter 4,
Block Reference.
Increase to Close Remaps the block’s scaling so that as the input increases, the
output decreases.
Faultstate to Value When set, the block’s faultstate behavior sets the output value
to the value in
FSTATE_VAL. When clear, the block’s
faultstate behavior leaves the output value at its current
setting.
Use Faultstate Value on Restart Causes the output value of output blocks to go to faultstate
value immediately after a device restart.
Target to Man if Faultstate Active When set, this sets the target mode of the block to manual
mode when faultstate goes active.
Use PV for BKCAL_OUT When set, this uses the process variable as the value for
BKCAL_OUT, instead of the setpoint.
Low Cutoff When set, this enables the low cutoff parameter.
