LO_LIM
The limit, in PV units, beyond which the low limit alarm is considered
active.

Linearization Types
Type Description
Direct The block output is directly taken from the transducer value:
Indirect The block output is scaled according to OUT_SCALE from the value in
FIELD_VAL:
Indirect
Square Root
The block output is scaled according to OUT_SCALE from the value in
FIELD_VAL. Before the field value is rescaled, the square root is taken.
Uninitialized An invalid setting. The device reports a configuration error with an
Uninitalized L_TYPE.
