AP - Absolute Pressure.
ASCII - American (National) Standard Code for Information Interchange.
Attribute - A parameter that provides information about an aspect of a database point. For example, the alarm
attribute is an attribute that uniquely identifies the configured value of an alarm.
B
Built-in I/O - I/O channels that are fabricated into the 3095FC and do not require a separate option. Also called
“on-board” I/O.

port of the 3095FC.
Configuration - Typically, the software setup of a device, such as a 3095FC, that can often be defined and changed
by the user. Can also mean the hardware assembly scheme.

Deadband - A value that is an inactive zone above the low limits and below the high limits. The purpose of the
deadband is to prevent a value such as an alarm from being set and cleared continuously when the input value is
oscillating around the specified limit. This also prevents the logs or data storage location from being overfilled with
data.
Directory View - The Communication Directory tree provides a tree style means of navigating through the PC
Comm Ports and the 3095FC Comm Ports setup screens.
