HI_PRI (Alarming)
The priority of the high limit alarm.
IN (Process, Scaling, Tuning)
The primary input of the block.
IN_1 (Process, Scaling, Tuning)
The secondary input of the block.
IO_OPTS (I/O, Options, Scaling)
A bitmask used to adjust the way I/O blocks (AI, DI, AO, and DO) operate.
Table B-5. 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 Causes the setpoint to track the process variable in Man .
SP-PV Track in LO or IMan Causes the setpoint to track the process variable in LO or IMan .
SP Track Retained Target Causes 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 .
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
When set, causes the output value of output blocks to go to
faultstate value immediately after a device restart. When clear,
uses the value in nonvolatile memory.
Target to Man if
Faultstate Active
When set, sets the target mode of the block to manual mode
when faultstate goes active.
