Rockwell Automation 22-COMM-L LonWorks Adapter - Manual (Page 69)

Glossary G-5
Neuron
 Chip
A microprocessor usually contained in each LonWorks node which
processes all LonTalk protocol messages, senses inputs, manipulates
outputs, implements application-specific functions, and stores
installation-specific parameters.
Node
An intelligent device connected to the network. Nodes are programmed
to send messages to one another in response to changes in various
conditions, and to take action in response to messages they receive.
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.”
P
PowerFlex 4-Class (Component-Class) Drives
The Allen-Bradley PowerFlex 4-Class (Component-Class) family of
drives include the PowerFlex 4, PowerFlex 40, and PowerFlex 400.
These drives can be used for applications ranging from 0.2 kW (0.25
HP) to 7.5 kW (10 HP).
Protocols
Rules that order how information is transmitted and presented. An “open
protocol” is one in which the manufacturer has made the language
“translation” available to anyone who wishes to use it.
R
Reference/Feedback
The Reference is used to send a setpoint (for example, speed, frequency,
torque) to the drive. It consists of one 16-bit word of output to the
adapter from the network.
Feedback is used to monitor the speed of a product. It consists of one
16-bit word of input from the adapter to the network.
S
SCPT (Standard Configuration Property Type)
SCPTs are standardized definitions of the units, scaling, encoding, and
meaning of the contents of configuration properties.
