Note: With the same setting, some units are represented
differently between the F OUNDATION Fieldbus
communication type and the HART or BRAIN
communication type of a digitalYEWFLO. Each unit
enclosed in brackets above shows the unit for the HART
or BRAIN communication type of a digitalYEWFLO,
corresponding to the preceding unit (for the F
OUNDATION
Fieldbus communication type).

OUT_SCALE:
Sets the range of output (from 0% to 100%).
Available units for OUT_SCALE are the same
as units for XD_SCALE in Table 6.2 and
percentage.
L_TYPE:
Specifi es the operation function of the AI1 block.
The factory default is “Direct”, so the input
delivered to CHANNEL is directly refl ected on
OUT. If set to “Indirect”, scaling by XD_SCALE
and OUT_SCALE is carried out and is refl ected
on OUT. “Indirect SQRT” is not used for a
digitalYEWFLO.
PV_FTIME:
Sets the time constant of the damping function
within AI block (primary delay) in seconds.
Alarm Priority:
Indicates the priority of the process alarm.
If a value of 3 or greater is set, an alarm is
transmitted. The factory default is 0. Four types
of alarm can be set: HI_PRI, HI_HI_PRI, LO_
PRI, and LO_LO_PRI.
Alarm Threshold:
Sets the threshold at which a process alarm is
generated. The factory default setting is a value
that does not generate an alarm. Four types of
alarm can be set: HI_LIM, HI_HI_LIM, LO_LIM,
and LO_LO_LIM.
