I/O Bus Expansion Cables

(Includes Instructions for Building Custom Length Cables)

Description

I/O bus expansion cables (IC693CBL300, 301, 312, 313, 314), called “Wye cables,” have a single

male 25-pin D connector on one end and a two-headed (one male, one female) 25-pin D connector

on the other end as shown in (A) of the figure. The 50 foot (15m) (IC693CBL302) cable has a

single male connector on the CPU baseplate end and a single terminated male connector on the

expansion baseplate end. The 3 foot cable (IC693CBL300) can also be used as a WYE adapter

cable to simplify building custom length cables (see the section “Cable Application Suggestions”

later in this Chapter).

Function of Cables

The I/O Bus expansion cables are used to extend the I/O bus to expansion or remote baseplates in

a Series 90-30 I/O system when additional I/O slots are needed or baseplates are required some

distance from the CPU baseplate. The prewired I/O bus expansion cables can be used for

connecting either expansion or remote baseplates. Where required cable length is not available in a

10-22

Series 90-30 PLC Installation and Hardware Manual - August 2002

GFK-0356Q

Cables

standard cable, a custom cable must be built (see the section “Building Custom Length I/O Bus

Expansion Cables” for detailed instructions).

Connecting the Cables

Connect the single male connector to the 25-pin female connector on the right side of the CPU

baseplate.

Connect the male connector on the dual connector end of the cable to the 25-pin female

connector on the first expansion baseplate.

Connect the unused 25-pin female connector on the dual connector end of the cable to either

the single male connector of a second I/O bus expansion cable to continue the I/O bus

expansion chain, or to an I/O bus Terminator plug if this is the last cable in the expansion

chain.

Important Notes About I/O Bus Expansion Cables

The maximum number of cables that can be included in an I/O expansion system is seven, and

the total maximum cable length between the CPU baseplate and the last expansion baseplate is

50 feet (15 meters). The total maximum cable length between the CPU baseplate and the last

remote baseplate is 700 feet (213 meters). Failure to observe these maximum cable lengths

could result in erratic operation of the PLC system.

CPUs 350 - 374 support a maximum of seven I/O expansion cables. CPUs 331 - 341 support a

maximum of four I/O expansion cables.

The 50 foot (15 meter) I/O bus expansion cable (IC693CBL302), which has a male connector

on each end, has the I/O bus terminating resistors built into the end connector on the cable. If

this cable is used, you would not install a separate terminator block.

Caution

I/O Bus Expansion cables should NOT be connected or disconnected with

power applied to the I/O expansion baseplate(s). Unexpected PLC operation

may result.

Cable Application Suggestions

In general, it is advantageous to use standard, factory-built cables, where possible, to save time and

avoid wiring errors.

Using Standard Cables

For connecting between baseplates (either between a CPU and expansion baseplate, between

two expansion baseplates or between two remote baseplates) in the same cabinet when a

standard length (0.5, 1, 2, 8, or 15 meters) will fit the need.

As a Wye jumper for custom built point-to-point cables (IC693CBL300 is often used for this).

This combination saves time since a point-to-point cable can be built much faster than a Wye

cable. An example of this is shown in Figure 10-23.

GFK-0356Q

Chapter 10 Cables

10-23

Using Custom Built cables

When you need a cable length not available in a standard size.

When a cable must be routed through a conduit that is not large enough for a standard cable’s

connector to fit through.

Building Custom Length I/O Bus Expansion Cables

This section provides details needed to create custom length I/O Bus Expansion cables.

Two Types of Custom Built Cables

The two types are:

Point-to-Point - these have a single male connector on one end and a single female connector

on the other end. These are usually used with the IC693CBL300 which supplies the Wye

connection. This combination saves time since a point-to-point cable can be built much faster

than a Wye cable.

Wye - these have a single male connector on one end and two connectors (one male and one

female) on the other end.

Components Needed to Build Custom Length I/O Bus Expansion Cables

Note: the special two-headed Wye connector used on the standard Wye cables

is not available as a separate component.

I/O Expansion Bus Termination

When two or more baseplates are cabled together in an expansion system, the I/O expansion bus

must be properly terminated. The I/O bus must be terminated at the last baseplate in an expansion

system. Each signal pair is terminated with 120 ohm, 1/4 watt resistors wired between the

appropriate pins, as follows (see the above table, also):

pins 16 - 17; 24 - 25;

20 - 21;

12 - 13;

8 - 9;

2 - 3

The I/O bus termination can be done one of the following ways:

■ By installing an I/O Bus Terminator Plug, catalog number IC693ACC307, on the last

expansion baseplate (local expansion baseplate or remote baseplate) in the system. The

Terminator Plug has a resistor pack physically mounted inside of a connector. The I/O Bus

Terminator Plug is shipped with each baseplate; only the last baseplate in the expansion chain

can have the I/O Bus Terminator Plug installed. Unused I/O Bus Terminator Plugs can be

discarded or saved as spares.

■ If an expansion system has only one expansion baseplate, the I/O bus can be terminated by

installing as the last cable, the 50 foot (15 meter) I/O Expansion cable, catalog number

IC693CBL302 or IC693CBL314. These cables have the termination resistors installed in the

end that connects to the expansion baseplate connector.

■ You can also build a custom cable with termination resistors wired to the appropriate pins for

installation at the end of the bus.

Shield Treatment

All GE Fanuc factory made cables are made with a continuous, or 100% shield. This means that

the braided cable shield is connected to the metal shell of the connector around the entire perimeter

of the connector. This provides a low impedance path to frame ground for any noise energy that is

coupled onto the cable shield.

For custom length cables made per Figure 10-18, the best noise immunity is achieved when using a

metallized connector cover that makes contact with the cable’s braided and foil shielding and with

the connector shell on the terminating end.

Note

It is not sufficient to only solder the drain wire to the connector shell. It is

required that the cable’s shield be continuous across the entire length of the

cable, including at the terminations. The figure below shows the recommended

method for folding the braided shield back before inserting the cable into a

metallized cover.

Figure 10-16. How to use Split-Ring Ferrules for Foil and Braided Cable Shield

For typical industrial applications, all expansion and remote baseplate cables can be made with

plastic shell covers and should be wired as shown in Figure 10-19. In either case, pin 1 should be

wired into both ends of the custom length cable and the recommendations listed below should be

followed for the Wye cables treatment in the remote (IC693CHS392/399) baseplates.

When using 100% shielded cables all local (CPU and expansion) baseplates in the system must be

solidly referenced to the same ground point or a potential difference between baseplates could

disturb signal transmission.

Alert for Users of Early Remote Baseplate Versions

In early remote baseplates versions, IC693CHS393E (and earlier) and IC693CHS399D (and

earlier), it is necessary to remove pin 1 of the mating cable where the cable plugs into the baseplate.

This means that when using a factory made Wye cable, such as IC693CBL300, you must break pin

1 out of the male end where it plugs into the remote baseplate before using it with one of these

baseplates. Custom built Wye cables for these baseplates should be built using Figure 10-20.

GFK-0356Q

Cables

Remote baseplates IC693CHS393F (and later) and IC693CHS399E (and later) have a change

inside the baseplate which eliminates the need to remove pin 1 from the mating cable. When using

factory made Wye cable with these baseplates, it is not necessary to remove pin 1 from the cable.

Custom built Wye cables for these baseplates can be made using either Figure 10-20 or Figure 10-

21. Figure 10-21 shows how the standard (factory made) Wye cables are made.

By removing pin 1 in custom built Wye cables made for the earlier versions of remote baseplates,

the pin 7 (0V) signal reference originates in the main (CPU) baseplate. In these earlier versions of

the remote baseplates, pin 1 was tied to pin 7 (0V) and also AC coupled to the remote frame

ground. When using these baseplates in combination with the 100% shielded Wye cables, the pin 7

(0V) reference would be improperly DC coupled to the remote frame ground through the D-

subminiature connector shell, which is DC coupled to the remote frame ground.

In the remote baseplates IC693CHS393F (and later) and IC693CHS399E (and later), the pin 1

shield signal is DC coupled to the remote frame ground and not attached to pin 7 (0V). This allows

the best noise immunity by providing a good continuous cable shield, and still allows the pin 7

(0V) signal reference to originate in the CPU baseplate without the need for removing pin 1 in any

factory or custom built cable. The D-subminiature connector shell is still DC coupled to the remote

frame ground.

Making a 100% Shielded Cable

Use the following steps to build a 100% shielded cable:

Strip approximately 5/8 inch of insulation from your custom cable to expose the shield.

Remove the male Pin 1 from any connector plugging directly into an older version remote

baseplate (IC693CHS393E, IC693CHS399D, or earlier).

Put split-ring ferrule over cable insulation (Figure 10-17).

Fold the shield back over top of the cable insulation and ferrule.

Place the collar of the metal hood over top of the folded shield and securely clamp the hood.

Test your cable for continuity between both connector shells. Connect an ohmmeter between

the shells and flex the cable at both ends. If the metallized connector hood is not making

proper contact with the cable shield at either end, the connection will show intermittent

continuity on the ohmmeter.

Plug the metal hooded cable onto a remote baseplate expansion port connector or into a GE

Fanuc WYE cable and securely tighten the two screws. Installing and tightening the screws

will electrically connect the shield to the remote baseplate frame ground, which should in turn

should be connected to earth ground as instructed in the “Installation” chapter, under the

heading “Baseplate Safety Grounding.”

IC693CBL303

Hand-Hand Programmer and Converter (IC690ACC900) Cable

Function of cable

The Hand-Held Programmer cable provides the connections that allow the Hand-Held Programmer

and the Programmable Logic Controller to communicate. This cable also provides the power

connections for the HHP, and a signal which indicates to the PLC that the HHP is attached to the

PLC serial port. It can also be used to connect the RS-485 serial port on the PLC to the RS-

422/RS-485 to RS-232 converter (IC690ACC900).

Cable Specifications

The prewired cable (IC693CBL303) is 6 feet (2 meters) long. If a different length cable is required

for connection to the converter, refer to the information below for specifications and wiring

information.

This information is essential if you intend to build your own cable. The recommended cable types

for this cable are listed below and depend on the length of the cable.

Same as for 30 feet. In addition, the+5 VDC logic power source for the

980 feet (300m)

converter cannot be supplied by the PLC. It must be provided by an

external power supply connected to the +5V and SG pins at the converter end of

the connector. The +5V pin at the PLC connector must not be connected to the

cable. The +5V and SG connections from the power supply must be isolated from

its own power line ground connection. Be sure that there is no connection between

the external supply and the PLC except the SG cable connection.

Catalog numbers are provided as suggestions only. Any cable having the same electrical characteristics is acceptable.

It is strongly recommended that you use stranded wire. Since it is sometimes hard to find a cable with the desired

number of twisted pairs (the Belden 9309 has an extra pair), you may end up with a cable with extra pairs.

A greater cable length between the PLC and the converter increases the possibility of noise coupling into the data and

converter logic power circuits within the cable. The cable should be as short as possible in noisy environments. In

extreme cases, additional noise protection measures, such as double-shielded cables, may be required.
