Rockwell Automation RECOMM-ENET EtherNet/IP Communications Module - Manual (Page 183)

Glossary Glossary-5
module - Devices such as drives, controllers, and computers
usually require an module to provide a communication interface
between them and a network such as EtherNet/IP. An module reads
data on the network and transmits it to the connected device. It also
reads data in the device and transmits it to the network.
The RECOMM-ENET EtherNet/IP module is a module that
connects SP600, GV6000 and LiquiFlo 2.0 drives to a Ethernet
network. Modules are sometimes also called “adapters,” “cards,”
“embedded communication options,” “gateways,” and “peripherals.”
non-volatile storage (NVS) - NVS is the permanent memory of a
device. Devices such as the module 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.”
OIM (Operator Interface Module) - A device that can be used to
configure and control a SP600, GV6000 or LiquiFlo 2.0 drive.
PCCC (Programmable Controller Communications Command) -
The protocol used by some controllers to communicate with devices
on a network. Some software products (for example, VS Utilities)
also use PCCC to communicate.
Peer-to-Peer hierarchy - A module that is configured for peer-to-
peer hierarchy can exchange data with a device on the network that
is not a scanner. This type of hierarchy can be set up so that a
scanner configures or transmits data to one SP600 drive, which
then sends the same configuration or data to other SP600 drives on
the network. To use a peer-to-peer hierarchy, you configure one
module to transmit data (2 or 4 words) and one or more modules to
receive the data.
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.
reference/feedback - The reference is used to send a reference
(for example, speed, frequency, torque) to the product. It consists of
one word of input to the module 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 a product. It consists of
one word of output from the module to the network. The size of the
word (either a 16-bit word or 32-bit word) is determined by the drive.
RSLogix - 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 a:
