Terms and Abbreviations
This term: Means:
1747-KFC15 SLC-based module
1756-CNB a 1756-CNB or 1756-CNBR module; a ControlLogix backplane to ControlNet bridge
1770-KFC15 referred to herein as the module
a.k.a. also known as
ACK a DF1 or ControlNet acknowledgement
ControlNet the communication architecture that allows the exchange of messages between
devices that follow the ControlNet specifications
It is a real-time, control-layer network that provides high-speed transport for both
time-critical I/O and messaging data. A ControlNet cable system can be either
single or redundant media.
DF1 DF1 protocol is an Allen-Bradley RS-232 proprietary data-link layer protocol that
combines features of subcategories D1 (data transparency) and F1 (two-way
simultaneous transmission with embedded responses) of ANSI x3.28
specification. The KFC uses DF1 protocol to communicate on the serial port.
DH+ Data Highway Plus network; existing Allen-Bradley peer-to-peer network for
messaging and program upload/download
DH+ PCCC message a PCCC message that originated from a device on a DH+ network
DHRIO Data Highway and Remote I/O
DST the destination address on a DF1 link
full duplex simultaneous send/receive between devices, point-to-point
half duplex data transmission in one direction at a time, usually point-to-multipoint
NAK a DF1 negative acknowledgement
NAP network access port; 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 repeaters, routers, bridges and gateways.
network address the network address of a node on the ControlNet cable system. This address 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.
new KFC Version 4.2 or later of the KFC firmware
node any physical device connecting to the ControlNet cable system that requires a
network address in order to function on the network.
NUT network update time; the rate at which access to the ControlNet network is
granted

P-4
Publication 1770-UM520C-EN-P - July 2004
old KFC Any 1747-KFC15 or 1770-KFC15 firmware released before v4.2, including version
2.2 (a.k.a. version B/B) and older firmware
parallel port input/output port for a device that transmits multiple data and control bits over
wires connected in parallel
PCCC Programmable Controller Communication Commands; an Allen-Bradley
communication protocol used on the Data Highway Plus network
repeater a two-port active physical layer 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 alternate media
(coaxial cable, fiber, etc.) and altering the topology of the network.
RIO Remote Input/Output; an Allen-Bradley remote input/output link that supports
remote, time-critical, I/O and control communication between a master PLC
controller and its remote I/O and adapter mode slave processors
RS-232C port a serial port that complies with accepted industry standards for serial
communications connections
SRC The source address on a DF1 link
segment trunkline sections connected via taps with terminators at each end, and with no
repeaters
serial port input/output connector for a device that transmits data and control bits
sequentially over a single transmission line. (See RS-232C port.)
standard PCCC message A PCCC message that originated from a device that is not on a DH+ network
subnet network segments connected by repeaters to make up one ControlNet network
tap the connection device between any ControlNet device and the trunkline. A tap is
required for each node and for both sides of each repeater.
terminator a special circuit that prevents signal reflections from occurring at the end of a
cable
trunkline the bus or central part of a cable system
trunkline section a length of trunkline cable between any two taps
