Table 4-14. 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 faultstate behavior sets the output
value to the value in

FSTATE_VAL

. When clear, the block

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.

Use PV for BKCAL_OUT

When set, uses the process variable as the value for

BKCAL_OUT

, instead of the setpoint.

Low Cutoff

When set, enables the AI low cutoff parameter.
