4.3 CONFIGURING THE DATABASE MODULES
The datapoints in the database modules must be changed to reflect required alterations in the fac-
tory standard configuration or when the instrument is re-configured. There are generally four data-
point parameter types contained in the eight database modules. The parameter types affect
Datalink communications, display indications, input-output signals, and alarm conditions. The
eight database modules are described in Table 4-2. Although it is not an absolute criterion, it is as-
sumed the modules will be configured in the table Item order; however, if the instrument is to be
connected to a Datalink network, item 7, Communication Module, should be configured first. By
configuring the Communication Module first, the instrument can function on the Datalink and the re-
maining datapoint values can be entered via the Datalink interrogator (master). Reference the ap-
plicable instruction bulletin (e.g., IB 53HC3300, IB53WS5000, or IB 53SU5000) for the procedure.
Table 4-2 is also a pointer to the descriptions of the database modules; the descriptions are pre-
sented as Tables 4-3 through 4-10. (The gray tone shading in the default cell of a datapoint indi-
cates the datapoint contents are left unchanged after default. See Section 5.5 for the default
procedure.)

Item Title Purpose See
Table
1 Analog Input Module This module is used to configure the voltage input
characteristics (e.g., input voltage range) and how the input
signal is interpreted (linear or square root representation). 4-3
2 Analog Output
Module The primary purpose of this module is to set the 0 - 20 mA
output signal relative to the displayed percent output. 4-4
3 Contact Input Module This module allows the action of the CCIs to be reversed
(normally a closed contact = 1, but can be change to = 0).
4-5
4 Contact Output
Module This module allows the action of a CCOs to be reversed
(normally a closed contact = 1, but can be changed to = 0). 4-6
5 Alarm Module The primary purpose of this module is to set the
instrument’s Alarm Index mode, Alarm Limits 1 & 2, and
Alarm Dead Band. 4-7
6 Totalizer Module The totalizers provide the sum of each analog input (ANI0-
3). This module is used to set input scaling factors, rollover
and dropout values, and to define display tags for each
totalizer. 4-8
7 Communication
Module This module is used to configure the Datalink port
parameters (e.g., baud rate, parity selection, etc.). 4-9
8 System Module This module is used to set the instrument tag name and the
display brightness. 4-10
