Glossary
configuration. The user sets the data that is sent to the drive using specific fault
configuration parameters in the adapter. When a fault action parameter is set to
use the fault configuration data and a fault occurs, the data from these parameters
is sent as the Logic Command, Reference, and/or Datalink(s).
Flash Update The process of updating firmware in a device. The adapter can be flash updated
using various Allen-Bradley software tools.
Gateway A device on a network that connects an individual network to a system of
networks. When a node needs to communicate with a node on another network,
a gateway transfers the data between the two networks. You need to configure the
address for the gateway device in the adapter if you want the adapter to
communicate with devices that are not on its network.
Hardware Address Each Ethernet device has a unique hardware address (sometimes called a MAC
address) that is 48 bits. The address appears as six digits separated by colons (for
example, xx:xx:xx:xx:xx:xx). Each digit has a value between 0 and 255 (0x00 and
0xFF). This address is assigned in the hardware and cannot be changed. It is
required to identify the device if you are using a BootP utility.
HIM (Human Interface Module) A device that can be used to configure and control a drive. The PowerFlex 22-
HIM-A3 or 22-HIM-C2S HIM can be used to configure PowerFlex 525 drives
and their connected peripherals.
Hold Last When communication is disrupted (for example, a cable is disconnected), the
adapter and its PowerFlex 525 drive can respond by holding last. Hold last results
in the drive receiving the last data received through the network connection
before the disruption. If the drive was running and using the Reference from the
adapter, it will continue to run at the same Reference.
Idle Action An idle action determines how the adapter and its PowerFlex 525 drive act when
the controller is switched out of run mode.
I/O Data I/O data, sometimes called “implicit messages” or “input/output,” is time-critical
data such as a Logic Command and Reference. The terms “input” (To Net) and
“output” (From Net) are defined from the controller’s point of view. Output is
produced by the controller and consumed by the adapter. Input is produced by
the adapter and consumed by the controller.
IP Addresses A unique IP address identifies each node on an EtherNet/IP network. An IP
address consists of 32 bits that are divided into four segments of one byte each. It
appears as four decimal integers separated by periods (xxx.xxx.xxx.xxx). Each
“xxx” can have a decimal value from 0 to 255. For example, an IP address could be
192.168.0.1.
