Glossary
Logix Designer
The Logix Designer application is the rebranding of RSLogix 5000 software and
will continue to be the product to program Logix 5000 controllers for discrete,
process, batch, motion, safety, and drive-based solutions. It is a 32-bit application
that runs on various Windows operating systems. Information about Logix
Designer software can be found at
.
Master-Slave Hierarchy
An adapter configured for a master-slave hierarchy exchanges data with the
master device. Usually, a network has one scanner which is the master device, and
all other devices (for example, drives connected to EtherNet/IP adapters) are
slave devices.
On a network with multiple scanners (called a multi-master hierarchy), each slave
device must have a scanner specified as a master.
NVS (Non-Volatile Storage)
NVS is the permanent memory of a device. Devices such as the adapter and drive
store parameters and other information in NVS so that they are not lost when the
device loses power. NVS is sometimes called “EEPROM.”
PCCC (Programmable Controller
Communications Command)
PCCC is the protocol used by some controllers to communicate with devices on
a network. Some software products (for example, DriveExplorer and
DriveExecutive) also use PCCC to communicate.
Ping
A message that is sent on the network to determine if a node exists.
PowerFlex 525 Drives
The Allen-Bradley PowerFlex 525 drives are part of the PowerFlex 520-series of
drives.
PowerFlex 523 Drives
The Allen-Bradley PowerFlex 523 drives are part of the PowerFlex 520-series of
drives.
Reference/Feedback
The Reference is used to send a setpoint (for example, speed, frequency, torque)
to the drive. It consists of one 32-bit word of output from the network to the
adapter. Feedback is used to monitor the speed of the drive. It consists of one 32-
bit word of input from the adapter to the network.
RSLogix
RSLogix software is a tool for configuring and monitoring controllers to
communicate with connected devices. It is a 32-bit application that runs on
various Windows operating systems. Information about RSLogix software can be
found at
.
Scanner
A scanner is a separate module (of a multi-module controller) or a built-in
component (of a single-module controller) that provides communication with
adapters connected to a network. See also Controller.
