Table 4-4. Analog Input (ANI) Module

Purpose: This module is used to configure input voltage characteristics (e.g., input voltage range), and how the
input signals are interpreted (linear or square root representation).

ANI H000 H001

0

This is the value in engineering units of the
measured input after all signal conditioning has
been applied.

Engineering
Span

SPAN C256 C257

100

This determines the upper range the analog
input represents in engineering units. The
upper range value equals Engineering Zero
plus Engineering Span.

ZERO

C276

C277

0

This is the lower range value.

Digital Filter
Index

DFILT B269 B270

3

This controls a first order filter that is applied
to the input signal. The time constant is
entered as an index value as follows:

0 -No Smoothing (no effect)

1 -0.05 s

2 - 0.1 s
3 - 0.3 s
4 - 0.7 s
5 - 1.5 s

6 - 3.1 s
7 - 6.3 s

8 -12.7 s
9 -25.5 s

10 -51.1 s

11 - 102 s
12 - 205 s
13 - 410 s
14 - 819 s

15 -1638 s

0 - 5 V Input

NOBIAS

L416

L417

0

Setting this parameter to 1 indicates the input
range is from 0 -5 volts (0 -20 mA). 0
indicates the input range is from 1 -5 volts (4 -
20 mA).

Square Root

Signal

SQRT L440 L441

0

When a 0, it indicates the analog input signal
should be interpreted linearly.
When 1, it indicates the analog input signal
should be interpreted as a square root
representation of the value. When square root is
selected, input signals less than 1% (10% input
range) forces the input to its zero value.

Calibrate
Zero

CIZ B263 B264

This is the calibration zero adjustment. This
parameter is factory set and should not need
adjustment
under normal operation.
See Section 5.3 for adjustment.

Calibrate
Span

CIS C296 C297

This is the calibration span adjustment. This
parameter is factory set and should not
need adjustment
under normal operation.
See Section 5.3 for adjustment.
