GE FANUC IC697CMM742 Communications Modules

10BaseT and 10Base2 network ports provide direct

connection to 10BaseT or 10Base2 network without an external transceiver

Standard 15-pin AUI network port allows choice

of 10Base5. 10Base2. 10BaseT, 10BaseF, or

10Broad36 medium with user-supplied 802.3-compatible transceiver

Firmware is pre-loaded for easy installation and is

maintained indefinitely; firmware is easily upgraded

in-system from PC attached to RS-485 serial port

The Ethernet Interface provides:

 Data exchange using configuration-based and

logic-based Ethernet Global Data

 TCP/IP communication services using SRTP

 Full PLC programming and configuration services

 Comprehensive station management and

diagnostic tools

Functions

The IC697CMM742 Ethernet Interface (Type 2)

provides high performance TCP/IP communications for

the IC697 PLC.

The Ethernet Interface (Type 2) plugs into a single slot

in an IC697 PLC rack and is configured with the IC641

PLC programming software. Up to four Ethernet

Interface (Type 2) modules can be installed in an IC697

PLC CPU rack.

The Ethernet Interface (Type 2) contains three network

ports: 10BaseT (RJ-45 connector), 10Base2 (BNC

connector), and AUI (15-pin D-connector). The

Ethernet Interface automatically selects the network

port in use. One network port may be used at a time.

The 10BaseT network port permits direct connection to

a 10BaseT (twisted pair) network hub or repeater

without an external transceiver.

The 10Base2 network port permits direct connection to

a 10Base2 (ThinWire) network without an external

transceiver.

The AUI network port permits attachment of a usersupplied AUI (Attachment Unit Interface, or transceiver

The AUI cable connects the Ethernet Interface to a

user-supplied transceiver that is directly connected to the

10Mbps Ethernet network. The transceiver must be 802.3

compatible and must have the SQE option enabled.

Transceivers are commercially available to operate on a

variety of 10Μbps media including 0.4 inch diameter

coaxial cable (10Base5), ThinWire coaxial cable

(10Base2), twisted pair (10BaseT), fiber optic (10BaseF),

and broadband cable (10Broad36).

The Ethernet Interface (Type 2) provides TCP/IP

communications with other IC697 and IC693 PLCs, host

computers running the Host Communications Toolkit or

CIMPLICITY
software, and computers running the

TCP/IP version of the MS-DOS or Windows based

programming software. These communications use the

proprietary SRTP and Ethernet Global Data protocols

over a 4-layer TCP/IP (Internet) stack.

Figure 1 shows the IC697 PLC in a basic Ethernet

communication system.

IEEE 802.3 Media

The Ethernet Interface (Type 2) can operate directly on

10BaseT or 10Base2 media via its 10baseT and 10Base2

network ports. These media are described below.

Additionally, the Ethernet Interface (Type 2) can

operate on any of the media listed below with the

appropriate user-supplied transceiver and transceiver

cable via its AUI network port.

10Base5 Coax: 10Base5 uses a 0.4 inch diameter 50-ohm

coaxial cable. The maximum length of a cable segment

(single span of cable) is 500 meters. The distance

between any two stations must be a multiple of 2.5

meters. A maximum of 100 stations is allowed on a

thickwire Ethernet segment.

10Base2 Coax: 10Base2 uses a 0.2 inch diameter 50-ohm

coaxial cable. The maximum length of a ThinWire cable

segment is 185 meters. A maximum of 30 stations is

allowed on a ThinWire Ethernet segment.

10BaseT: 10BaseT uses a twisted pair cable of up to 100

meters in length between each node and a hub or

repeater. Typical hubs or repeaters support 6 to 12

nodes connected in a star wiring topology.

10BaseF: 10BaseF has two variations that both use the

same type of fiber optic cable: 10BaseFP can support up

to 33 nodes at distances of up to 500 meters from a

passive star; 10BaseFL supports up to 2000 meters

between a node and a repeater (a multi-port repeater

would thus constitute a star). Additionally, 10BaseFB

provides a means of interconnecting (only) repeaters by

up to 2000 meters of (the same) fiber optic cable.

Note

Various Ethernet baseband media listed above

can be interconnected by appropriate repeaters. Capabilities and limitations are defined in

IEEE 802.3 Chapter 13. System Considerations for

Multi-Segment Networks.

10Broad36: 10Broad36 uses 75-ohm coaxial cable and

CATV-like media components (taps, amplifiers, headend

translators, etc.) to support hundreds of nodes at

distances of up to 2800 meters. Broadband cannot be

connected to baseband via repeaters. Broadband cable

plant design and installation must be in accordance with

IE
