Ping

A message that is sent by a DPI product to its peripheral devices. They use
the ping to gather data about the product, including whether it can receive
messages and whether they can log in for control. On EtherNet/IP, a ping
can be used to determine if a node exists.

PowerFlex 7-Class (Architecture Class) Drives

The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and, at
the time of publication, includes the PowerFlex 70, PowerFlex 700,
PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000
drives.

PowerFlex 750-Series (Architecture Class) Drives

The Allen-Bradley PowerFlex 750-Series of drives supports DPI and, at the
time of publication, includes the PowerFlex 753 and PowerFlex 755 drives.

R

Reference/Feedback

The Reference is used to send a setpoint (for example, speed, frequency, and
torque) to the drive. It consists of one word of output to the adapter from the
network. The size of the word (either a 16-bit word or 32-bit word) is
determined by the drive.

Feedback is used to monitor the speed of the drive. It consists of one word
of input from the adapter to the network. The size of the word (either a
16-bit word or 32-bit word) is determined by the drive.

RSLogix 5/500/5000 Software

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

S

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.

Status Indicators

LEDs that are used to report the status of the adapter, network, and drive.
They are on the adapter and can be viewed on the front cover of the drive
when the drive is powered.

Subnet Mask

An extension to the IP addressing scheme that lets you use a single network
ID for multiple physical networks. A bit mask identifies the part of the
address that specifies the network and the part of the address that specifies
the unique node on the network. A ‘1’ in the subnet mask indicates the bit is
used to specify the network. A ‘0’ in the subnet mask indicates that the bit is
used to specify the node.
