Glossary of Terms and Abbreviations

This manual may use the following terms as defined below:

ControlNet

The communication archite ct ure that allows the exchange of messages
between devices t hat follow the ControlNet spe cifications. ControlNet is
a real-time, control-layer network that provides high-spee d transport for
both time-critic al I/O and message data. A ControlNet network can be
either single or redunda nt media.

DF1

Allen-Bradley’s RS-232 proprietary protocol.

Full Duplex

The ability to simultaneously send/receive data between devices,
point-to-point.

Half Duplex

The data transmission in one dir ection at a time, usually
point-to-multipoint.

1747-5.34 - June 1998

P-4

NAP (Network Access Port)

An input/output (RJ-45 style) connector for a programming terminal to
gain full access to the network.

Network

A collection of connected nodes (end devices). The connection paths
between any pair of nodes can include repeate rs, routers, bridges, and
gateways.

Network Addr e ss

The network address of a node on the ControlNet network. This addre ss
must be in the range of 1 to 99 (decimal) and be unique to that subnet. A
subnet can contain a maximum of 99 nodes.

Node

Any physical device connect ing to the Control Net network tha t requires a
network address in order to funct ion on the network.

NUT (Network Update Time)

The rate at which access to the network is granted.

PCCC (Programmable Controller Communications
Commands)

An application-leve l command set that Allen-Bradley programmable
controllers use to communicate across networks.

Repeater

A two-port active physical la yer component that reconstructs all traffic it
hears on one network segment side and retransmits it to another network
segment side. Repeaters allow for extensions in network distance,
conversion to altern ate media (coaxial cable, fiber, etc.) and altering the
topology of the network.

1747-5.34 - June 1998

RS-232C Port

A serial port that complies with accepte d industry standards for seria l
communications connections.

Segment

Trunkline sections connected via taps with term inators at each end, and
with no repeat ers.

Serial Port

Input/output connec tor for a device that transmits data and controls bits
sequentially over a sin gle transmission line. (See RS-232C port.)

Subnet

Network segments connected by repe at s to make up on ControlNet
network.

P-5

Tap

The connection device betwee n any devic e and the trunkline. A tap is
required for each node and for both sides of each repeater.

Terminator

A special c ircuit that pre vents signal reflections form occurring at the e nd
of the cable.

Trunkline

The bus or central part of a cable system

Trunkline Section

A length of trunkline cable between any two taps.

Overview of the 1747-KFC15 Module

The KFC15 module enables you to communicate with your SLC500
processor using a ControlNe t network. You can examine the

processor’s ladder program, monitor program operation, and make
program changes. The KFC15 module acts as a bridge between a
ControlNet network and your SLC500 processor’s RS-232C serial
port.

The KFC15 module connects to the ControlNet network from one
(channel A) or both o f it s two BNC connectors via a standar d, one-meter,
ControlNet coaxial tap. For redundant media, both connectors are used.

RS-232C

The KFC15 module has two ports for device connections:

RS-232C serial por t—provides half- or full -duplex communication wi th
a serial port on your SLC500 processor.

network access port—lets you connect a ControlNet programming
terminal or other device to the KFC15 module for full network access
without disrupting the cable wiring

The serial port uses DF1 protocol while the network access port handles
ControlNet packets directly .

Status LEDs and the dot matr ix disp lay on the fr ont of the KFC15 indica te
current operating co nditions of the unit and communication activities
taking place through the ports.
