Analog-Input Block
I.7 Configure the AI block
A minimum of four parameters are required to configure the AI Block. The parameters are
described below with example configurations shown at the end of this section.
CHANNEL
Select the channel that corresponds to the desired sensor measurement. The Rosemount 5400
measures Level (channel 1), Distance (channel 2), Level Rate (channel 3), Signal Strength
(channel 4), Volume (channel 5), and Internal Temperature (channel 6).
L_TYPE
The L_TYPE parameter defines the relationship of the transmitter measurement (Level,
Distance, Level Rate, Signal Strength, Volume, and Internal Temperature) to the desired output
of the AI Block. The relationship can be direct or indirect root.
Direct
Select direct when the desired output will be the same as the transmitter measurement (Level,
Distance, Level Rate, Signal Strength, Volume, and Internal Temperature).
Indirect
Select indirect when the desired output is a calculated measurement based on the transmitter
measurement (Level, Distance, Level Rate, Signal Strength, Volume, and Internal Temperature).
The relationship between the transmitter measurement and the calculated measurement will
be linear.
Indirect square root
Select indirect square root when the desired output is an inferred measurement based on the
transmitter measurement and the relationship between the sensor measurement and the
inferred measurement is square root (for example, level).
