4 CONFIGURATION PARAMETERS
The configuration parameters provide the latitude to define the instrument’s personality attributes, so that
while still functioning within its designed specifications, it can perform application requirements with greater
refinement. Typical configuration parameters are the instrument’s indicator zero point and span, the display
tag names, engineering units of the displayed process value, and alarm limits, etc. IT IS NOT NECESSARY
TO DEFINE ALL OF THE CONFIGURATION PARAMETERS, as commonly used preset values may not have
to be altered and certain parameter selections eliminate others.
Although all resident in a memory database as datapoints, the configuration parameters are clustered into
modular groups that may have specific hardware identities (e.g., the ANI, ANO, CCI, and CCO circuits
illustrated in Figures 4-1 through 4-4), or may represent software controlled functions that are not specific to
any one hardware element.
4.1 Datapoint Types
A parameter can be any one of five data types. Each data type represents a specific data format:
integers, alphanumeric text strings, etc. A database module containing multiple parameters can
have a mix of data types. The data types are defined in Table 4-1 as follows:
Table 4-1. Datapoint Types
Type Byte
Size
Format
L 1 Bit Represents a single binary bit that can have the value of 0 or 1.
B 1 Represents a positive integer with values from 0 to 255.
C 3 Represents a real analog (floating point) value that has a resolution of one part in 32,768 (15 bits)
and a dynamic range of ± 10
38 .
H 5 Represents a high precision analog (floating point) value that has a resolution of one part in 2
billion (31 bits) and a dynamic range of ± 10
38 .
A 10 Represents a text string that can be 10 characters long.
F 5 Represents text strings that can be 5 characters long.
4.2 Factory Standard Calibration
The instrument is shipped from the factory configured as summarized in Table 4-2.

Datapoint Value Attribute
B000 1 This value indicates Single Loop PID Controller operation.
C106 100 Proportional Band = 100%.
C107 0 No Reset (TR) action.
C108 0 No Derivative (TD) action.
B335 1 No Alarms.
C256 100 ANI0 Engineering Span Input (Process Variable [PV] Input) = 0% - 100%.
L416 0 ANI0 Input Voltage Range is 1 -5 V.
L106 1 Reverse Switch is set so that the instrument output decreases as PV increases.
L115 0
Remote Setpoint Disabled indicates the setpoint value established in Local mode
remains in effect when the instrument is placed in Remote mode.
