hierarchy can be set up so that a scanner configures or transmits data to
one PowerFlex 750-Series drive which then sends the same
configuration or data to other PowerFlex 750-Series drives on the
network. To use a peer-to-peer hierarchy, you configure one adapter to
transmit data and one or more adapters to receive the data.
Ping
A message that is sent on the network to determine if a node exists.
PowerFlex 750-Series (Architecture Class) Drives
The Allen-Bradley PowerFlex 750-Series drives are part of the
PowerFlex 7-Class family of drives.
R
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 to the
adapter from the network.
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 5/500/5000
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
Status indicators are 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.
For example, a subnet mask on a network may appear as follows:
11111111 11111111 11111111 11000000 (255.255.255.192). This
