Tag number (PD_TAG) Set to “FT1003” by default unless otherwise specifi ed when ordered.
Output mode (L_TYPE) “Direct”
Upper and lower calculation range limits
and unit (XD_SCALE) The upper range limit will be set to the
maximum fl ow rate range specifi ed in the
registered sizing data, or to the 0 to 10 m
3 /h
range in case of UNCALIBRATION.
–40 to +260°C or –40 to +482°F
Upper and lower output range limits and
unit (OUT_SCALE) _
Node address
Set to 0xF2 unless otherwise specifi ed when ordered.
Explanation of parameters:
(1) XD_SCALE: Defi nes the input values from the transducer block (input range of the sensor) corresponding
to 0% and 100% values in the calculation inside the AI function block. For a digitalYEWFLO,
the values set as the fl ow span or temperature range (option) are stored in this parameter.
(2) OUT_SCALE: Output scaling parameter. Defi nes the output values corresponding to 0% and 100% values
in the calculation inside the AI function block.
(3) L_TYPE: Determines whether the values passed from the transducer block (sensor) should be
output without processing (“Direct”) or through scaling conversion based on OUT_SCALE
(“Indirect”).
