Value Parameter

Item settings, depending on what they are, use various value types. Table 10 provides a list of the

possible value types and their description.

Table 11 shows the various groups, the settings contained within, and the type of value it requires.

Table 10

Value types

Type

Definition

Numeric

An integer numeric value in the units indicated by the item name. For example, a System Voltage

Rating of 480 would indicate 480 volts.

Scaled

Similar to the Numeric, this value type is an integer that has been scaled, usually to remove

decimal points that would normally appear within the value. In this case, a value of 2.5 may actually

be input as simply 25. For all Scaled types, the scaling appears in Table 11.

String

Certain settings are represented by alphanumeric character strings, such as setting the System

Model Number to Liebert STS2.

Enumeration

This type uses an indexed list to represent possible choices. One example is the Modem Baud

Rate which uses a value of 0 to select 2400 bps, 1 for 9600 bps, and 2 for 19200 bps.

Bit-packed

This type of value uses a hexadecimal binary word, where each of the sixteen bits in the word has

the value of 1 (True) or 0 (False). Although somewhat difficult to use, it packs a large amount of

data within a single entry. A detailed description of this type appears in section 12.1.3 - Setting

Bitpacked Options with the Terminal on page 81.

Event Masks

This type is a specially formatted and is used to customize the behavior of each fault and alarm in

the system. See 12.1.4 - Setting Event Masks with the Terminal on page 83 for instructions on

configuring Event Mask parameters.
