Value Parameter

Item settings, depending on what they are, use various value types.Table 14 provides a list of the possible value types and their description.

Table 14	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.
		Similar to the Numeric, this value type is an integer that has been scaled, usually to remove decimal
Scaled		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 15.
String		Certain settings are represented by alphanumeric character strings, such as setting the System
		Model Number to ProductName.
Enumeratio		This type uses an indexed list to represent possible choices. One example is the Modem Baud Rate
n		which uses a value of 0 to select 2400 bps, 1 for 9600 bps and 2 for 19200 bps.
		This type of value uses a hexadecimal binary word, where each of the sixteen bits in the word has
Bit-packed		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.
Event		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 for instructions on configuring
Masks
		Event Mask parameters.
