programmers and printers).

PLC (Programmable Logic Controller)

A solid-state industrial control device which receives signals from

user-supplied control devices, such as switches and sensors, imple-

ments them in a precise pattern determined by ladder diagram

based application programs stored in user memory, and provides

outputs for control of processes or user-supplied devices such as re-

lays or motor starters. It is usually programmed in relay ladder logic

and is designed to operate in an industrial environment.

PLC Fault Table A fault table listing PLC faults. These faults are identified by time,

date, and location.

Programmer

Usually consists of a personal computer running the PLC program-

ming software.

Programmer Port

The serial port on the power supply module, accessible through a

15-pin connector, to which the programmer must be connected in

order to communicate with the PLC. Both the PC-based program-

mer and the Hand-Held Programmer connect to this port.

Programming Software

That portion of the programming software package that is used to

create ladder logic programs.

PROM (Programmable Read Only Memory)

A retentive digital device programmed at the factory and not easily

changed by the user. PROM usually contains operating system

instructions for internal system use.

Rack

A Series 90-30 baseplate when it has modules installed in it.

Rack Number

A unique number, assigned to each rack for identification purposes.

The numbers range from 0 to 4, assigned for a system with a Model

331 - 341 CPU, or from 0 to 7 for a Model 351 - 364 CPU. The CPU

(main) rack is always rack 0.

Rack Number DIP Switch

A three-position DIP switch, located on an Expansion or Remote base-

plate directly behind the power supply, used to assign a rack number.

RAM (Random Access Memory)

A solid-state memory that allows data to be stored and accessed at

random locations. This memory stores program files and related

data while power is applied to the system. This type of memory,

however, is volatile. Because data stored in RAM is lost under no-

power conditions, a backup battery is usually used to retain the con-

tents under those conditions. The backup battery used in the Series

90-30 PLC is a long-life lithium battery mounted on the power sup-

ply, PCM, and ADC modules.

Reference Type

A specific group of memory types in the Series 90-30 PLC (for example,

%I references discrete inputs and %Q references discrete outputs).

The % symbol is used to distinguish machine references (memory ad-

dresses) from nicknames.

A group of 16 consecutive bits in register memory, referenced as a

%R address. Each register is numbered, beginning at %R00001.

and for bit manipulation.

Release Lever

A molded lever on the bottom of each Model 30 I/O module, which

when depressed upwards, releases the module in its slot to allow

removal of the module.

Remote Baseplate

A 5 or 10-slot baseplate added to a system when the application calls

for the presence of a baseplate more than 50 feet from the CPU base-

plate. CPU models 331, 340, or 341 support up to four remote base-

plates (or a combination of remote and expansion baseplates as long as

the distance and cable requirements are followed) with the last remote

baseplate no more than 700 feet (213 meters) from the CPU baseplate.

CPU models 350 - 364 support up to seven expansion baseplates.

Removable Terminal Block

The removable assembly which attaches to the front of an I/O mod-

ule, and contains the screw terminals to which field wiring is con-

nected.

Restart Pushbutton

A pushbutton on the front of the module used to reinitialize the

PCM, ADC, or GDC module, or to initiate a hard or soft reset of the

module. The TCP/IP Ethernet Interface module also has a restart

pushbutton which has multiple functions.

RUN Mode

A condition or state of the Series 90-30 PLC, where the CPU

executes the application program. RUN mode executes in the RUN/

OUTPUTS ENABLED mode only. In RUN/OUTPUTS ENABLED,

all portions of the program sweep are executed.

Scan

Also called “Sweep.” The routine that the CPU performs repeatedly

in performing its sequence of tasks. The basic scan runs in this se-

quence: housekeeping tasks, input tasks, ladder logic solving, out-

put tasks, programmer communications, and option module com-

munications. Once the CPU reaches the end of a scan, it begins

another one and continues this sequence until stopped by a fault or

by human intervention. Each scan takes a measurable amount of

time (milliseconds) , which may having an impact on time-critical

tasks.

A-6

Series 90-30 PLC Installation and Hardware Manual - October 1999

GFK-0356P

Serial Communications

A method of data transfer, whereby the bits are handled sequential-

ly rather than simultaneously, as in parallel data transmission.

Serial Port

An RS-485/422 port on the PLC, accessible through a 15-pin connec-

tor, to which the programmer must be connected in order to com-

municate with the PLC. Both the Logicmaster 90 programmer and

the Hand-Held Programmer connect to this port. The PLC can

communicate with other serial devices through this port. A convert-

er is needed when communicating with an RS-232 device through

this port.

STOP Mode

A condition or state of the Series 90-30 PLC, where the CPU no

longer executes the application program. STOP mode can be STOP/

NO IOSCAN or STOP/IOSCAN. In STOP/NO IOSCAN mode, the

PLC only communicates with the programmer and other devices

(GBC, PCM, etc.), recovers faulted boards, reconfigures boards and

executes background tasks. All other portions of the sweep are

skipped. In STOP/IOSCAN mode, the PLC CPU can monitor I/O.

This feature provides a way to monitor and debug I/O without

executing the application program.

Storage

Used synonymously with memory.

Sweep

See “Scan.”

Termination Resistor Pack

A resistor pack used to properly terminate the I/O Expansion Bus

signals. It is physically installed inside of a terminator plug

(IC693ACC307), or termination resistors are connected internally in

the 50 foot I/O bus expansion cable (IC693CBL302).

Terminator Plug A connector containing a resistor pack which must be installed at

the end of the I/O Expansion Bus chain to properly terminateI/O

bus signals. This plug must be installed on the unused connector

on the last I/O expansion cable in the I/O Expansion Bus chain. Un-

expected system operation may occur if the bus is not properly ter-

minated.

User Memory

The portion of system memory in which the application program

and data is stored. This memory is battery-backed CMOS RAM.

User Reference Type

A reference assigned to data which indicates the memory in which it

is stored in the PLC. References can be either bit-oriented (discrete)

or word-oriented (register).

Volatile Memory A type of memory that will lose the information stored in it if power

is removed from the memory devices. It requires a backup battery

for retention of contents of memory. In the Series 90-30 PLC, a lithi-

um battery is used for this purpose.

to -7 Volts. The driver output must be capable of "

2 V minimum into 100 ohms. The

driver output impedance must be at least 120 K ohms in the high impedance state. The

receiver input resistance is 12 K ohms or greater. Receiver sensitivity is "

200 millivolt.

Caution

Care must be taken that common mode voltage specifications are met.

Common mode conditions that exceed those specified will result in

errors in transmission and/or damage to Series 90 PLC components.

When the common mode voltage specification is exceeded, a port

isolator such as the GE Fanuc IC690ACC903 must be used. See

Appendix G for details on this port isolator.

25-pin male D-Subminiature Type, Cannon DA25S (solder pot) with DB110963-3

hood or equivalent (standard RS-232 connector)

Computer grade, 24 AWG (.22 mm²), minimum with overall shield

Catalog Numbers: Belden 9505, Belden 9306, Belden 9832

Cable:

These cables provide acceptable operation for data rates up to 19.2 Kbps

as follows:

RS-232: 50 feet (15 meters) maximum cable length

RS-422/RS-422:

4000 feet (1200 meters) maximum length. Must not

exceed the maximum RS-422 Common Mode specifi-

cation of +7V to -7V. Isolation at the remote end may

be used to reduce or eliminate Common Mode voltages.

For distances under 50 feet (15 meters), almost any twisted pair or shielded

twisted pair cable will work, as long as the wire pairs are connected correctly.

When using RS-422/RS-422, the twisted pairs should be matched so that both

transmit signals make up one twisted pair and both receive signals make up the

other twisted pair. If this is ignored, cross-task resulting from the mismatching

will affect the performance of the communications system.

When routing communication cables outdoors, transient suppression devices can

be used to reduce the possibility of damage due to lightning or static discharge.

Care should be exercised that all connected devices are grounded to a common point.

Failure to do so could result in damage to the equipment.

Series 90 PLC Serial Port

The Series 90 PLC serial port is compatible with RS-422. An RS-232 to RS-422 converter

is required to interface to systems that provide RS-232 compatible interfaces. The Series

90 PLC, RS-422 serial port provides the physical connection for SNP communication.

This port is a 15-pin D-type female connector located as follows:

Series 90-70 PLC and Series 90-20 - CPU Module

Series 90-30 PLC - Power Supply

Figure C-1 shows the serial port orientation and connector layout for the Series 90 PLC

types (note that the orientation of the connector on the Series 90-20 CPU is rotated 90

degrees from the Series 90-30 connector with pin 1 to the upper right). Table C-2 shows

the pin numbering and signal assignment applicable to both PLCs.

** Termination resistance for the Receive Data (RD) signal needs to be connected only on units at the

end of the lines. This termination is made on the Series 90 PLC products by connecting a jumper

between pins 9 and 10 inside the 15-pin D-shell with the following exception. For Series 90-70

PLCs with Catalog Numbers IC697CPU731J, and IC697CPU771G and earlier the termination for

RD at the PLC is implemented by a jumper between pins 9 and 11.

RS-232/RS-485 Converter

IC690ACC901 Miniconverter Kit

This kit consists of an RS-422 to RS-232 miniconverter, a 6 foot (2 meter) serial cable, and

a 9-pin to 25-pin serial port converter plug. This miniconverter is documented in

Appendix F. This miniconverter has replaced the older, larger, obsolete IC690ACC900

converter.

IC690ACC900 Obsolete Converter

The obsolete RS-232/RS-485 Converter (IC690ACC900) converts from RS-232 to

RS-422/RS-485 communications. The converter has one 15-pin female D-type port, and

one 25-pin female D-type port.

This converter is no longer available. Please substitute the IC690ACC901 miniconverter.

Information about this converter is included in this manual for reference and

troubleshooting purposes.

For detailed information on the converter, refer to Appendix D. Examples of serial cable

diagrams, which include the converter, are provided in the remainder of this appendix..

Serial Cable Diagrams

This section describes only a few of the many and various Point-to-Point, and Multidrop

serial port connections for Series 90 PLCs.

In the point-to-point configuration only two devices can be connected to the same

communication line. The communication line can be directly connected using RS-232 (50

feet, 15 meters maximum) or RS-485 (4000 feet, 1200 meters maximum). Modems can be

used for longer distances.

Note

The cable connector for the Series 90-70 and Series 90-30 PLCs serial port

must be a right angle connector in order for the hinged door on the

module to close properly. Refer to Table C-1Connector/Cable

Specification.

Multidrop Connections

In the multidrop configuration, the host device is configured as the master and one or

more PLCs are configured as slaves. This method can be used when the maximum

distance between the master and any slave does not exceed 4000 feet (1200 meters). This

figure assumes good quality cables and a moderately noisy environment. A maximum of

8 slaves can be connected using RS-422 in a daisy chain or multidrop configuration. The

RS-422 line must include handshaking and use wire type as specified in the “Cable and

Connector Specifications” section.

The following illustrations shows wiring diagrams and requirements for connecting a

Workmaster II or IBM-PS/2, Workmaster, IBM-AT/XT or compatible computer to Series 90

NOTE: This product is no longer available. This appendix is for

reference for those already using this converter. We recommend the

IC690ACC901 as a replacement for most applications (see Appendix F

for details).

This appendix provides a detailed description of the RS-422/RS-485 to RS-232 Converter

(IC690ACC900) for the Series 90 Programmable Logic Controllers.

Features

Provides the Series 90 PLCs with an interface to devices that use the RS-232

interface.

Allows connection to programming computer without a Work Station Interface

board.

Easy cable connection to either a Series 90-70 PLC or a Series 90-30 PLC.

No external power needed; operates from +5 volt DC power on the Series 90 PLC

backplane.

Convenient, light weight self-contained unit.

Functions

The RS-422/RS-485 to RS-232 Converter provides an RS-232 serial interface for the Series

90-70 and Series 90-30 PLCs, which have a built-in RS-422/RS-485 interface. Specifically,

it provides a serial connection between a Series 90-30 or Series 90-70 PLC serial port and

the serial port on the programming computer without the need for a Work Station

Interface to be installed in the computer. The programming computer can be a

Workmaster II computer, or IBM PS/2 or compatible computer.

Location in System

The RS-422/RS-485 to RS-232 converter is a free-standing device which requires two

cables as the connections between the PLC and the programmer. Its location is limited

only by the length of the connecting cables as listed in the interface specifications (see

GFK-0356P

D-1

Obsolete Product

Table 5). The cable at the PLC end that connects to the RS-422/RS-485 connector on the

converter can be up to 10 feet in length (without an external source of +5 VDC) and up

to 1000 feet (300m) in length with an external source of +5 VDC. The cable from the

RS-232 connector on the converter to the programming computer ’s serial port can be up

to 50 feet (15m) in length.

Installation

Installation of the RS-422/RS-485 to RS-232 Converter consists of connecting two cables.

Select the proper cables for your installation. Prewired cables (see below) are available

from GE Fanuc, or if cables of different lengths are required by your application, you can

build your own cables. Specifications for building these cables are provided later in this

appendix.

You do not need to connect an external source of power to the converter for a cable

length of 10 feet, or less, since the necessary power connections of +5 VDC and signal

ground are derived from the PLCs backplane bus through the cable which connects to

the Series 90-30 or 90-70 PLC.

Select one of the three RS-232 compatible cables (10 feet in length) that will connect

the programmer ’s (or other serial device) RS-232 serial port to the RS-232 port on

the converter. The catalog numbers of these cables are: IC690CBL701 (use with

Workmaster industrial computer, or IBM PC-XT or compatible personal computer),

IC690CBL702 (use with IBM PC-AT or compatible personal computer), and

IC690CBL705 (use with Workmaster II industrial computer, or IBM PS/2 or

compatible personal computer).

A standard 6-foot cable (HHP compatible) is available to connect the RS-422/RS-485

port on the converter to the RS-485 port on the Series 90-30 or Series 90-70 PLC. The

catalog number of this cable is IC693CBL303.

Installation of these cables should be done with the PLC powered-down.

Connect the 25-pin male connector on the 10 foot cable to the 25-pin female

connector on the converter.

Obsolete Product

Connect the female connector (9-pin or 25-pin) on the opposite end of this cable to

the male RS-232 connector (serial port) on the selected programming (or other serial)

device. If you build you own cable, use a connector that is compatible with your

serial device.

Notice that both ends of the 6-foot RS-422/RS-485 compatible cable are the same; a

15-pin male connector is attached at both ends. Connect one end of this cable to the

15-pin female connector on the RS-422/RS-485 connector on the converter.

Connect the other end of this cable to the 15-pin female connector, which interfaces

to the RS-485 compatible serial port on the Series 90-30 or Series 90-70 PLC. For the

Series 90-30 PLC, this connector is accessed by opening the hinged door on the

power supply. The serial port connector for the Series 90-70 PLC is on the CPU

module, and is accessed by opening the hinged door on the module.

Cable Description

The serial connection to the Series 90-70 PLC (see Figure D-1) is to the RS-422/RS-485

compatible serial port connector, located at the bottom of the CPU module behind the

hinged door, through an available 6 foot (2 meter) serial interface cable - IC693CBL303.

Wiring information and recommended cable and connectors are provided for those who

may want to build their own cable having a different length.

The serial connection to the Series 90-30 PLC is to the RS-485 compatible serial port

connector located behind the hinged door on the right front of the power supply,

through the same 6 foot serial interface cable, IC693CBL303, or equivalent, Figure D-2).
