FANUC Series 90-30 PLC. Installation and Hardware Manual (GFK-0356Q)

In the rung shown above, the %SA011 contact will close when a low battery is detected by the

PLC. This will turn on the %Q output coil, which addresses an output module’s output that will

turn on a warning light. An alternate method would be to communicate the status of the coil

(which, in that case, would probably be a %M coil) to a Human to Machine Interface (HMI)

terminal such as a GE Fanuc CIMPLICITY HMI unit. The HMI could be programmed to display a

warning message when that particular bit goes to a logic 1. For more information about System

Reference bits and ladder logic programming, see the Series 90-30/20/Micro PLC CPU Instruction

Operating Without a Memory Backup Battery

Whether it would be to your advantage to use a battery-less scheme depends on your application.

There are various advantages and disadvantages to consider in making your decision.

Possible Advantage

The obvious advantage of operating without a memory backup battery is that you are freed from

the need to maintain the battery. To be able to run without a battery, you need to have a PROM

device - either an EPROM, EEPROM, or Flash PROM - installed in your system. These devices

can store program logic, configuration, and register values without the need for a backup battery,

and you can configure your CPU to read the contents of PROM into RAM memory each time the

PLC is powered up.

Possible Disadvantages

Information is not stored to your PROM device automatically. To store information, you must stop

the PLC, then use a programming device to tell the CPU to write the current PLC (RAM) memory

contents to the PROM device. This requirement may make battery-less operation undesirable for

many users. For example, in many applications, important data is gathered and stored in RAM

count of parts produced, etc. This constantly changing data is not being copied automatically to

the PROM device. It only exists in RAM memory. Therefore, if power is lost and there is no

RAM memory backup battery, this data will be lost.

However, one way to preserve data in a battery-less system is to send it over a network to a

computer that can store the data on its hard drive. Also, static data (data that doesn’t change)

contained in RAM memory, such as mathematical constants or look-up table type information, can

be stored initially in PROM and automatically written back to RAM each time the PLC powers up.

Another consideration is that if you change your program (or configuration), someone will have to

remember to write the changed information to the PROM device. If that step is forgotten, the

change only exists in RAM memory, and in a battery-less system, it will be lost the next time

power is removed from the PLC.

Configuring a Battery-Less System

Here are the basic steps to configure a system to run battery-less. When configured this way, the

contents of PROM memory will be written into RAM memory each time the PLC powers up.

■ Equip your CPU with a PROM device. On some CPUs a PROM device is purchased as an

option; on others, it is a standard feature. For a table that identifies the standard PROM

configuration for each CPU, see “CPU Firmware and PROM Configurations” in chapter 5.

■ There are three CPU configuration parameters involved. Configure them as follows: Pwr Up

Mode: RUN; Logic/Cfg: PROM; Registers: PROM.

■ Store your folder (include Program Logic, Configuration, and Register Data) to the PLC. This

places your entire folder into RAM (working) memory.

■ Write PLC (RAM) memory to the PROM device. Make sure you write all data (Program

Logic, Configuration, and Register Data) to the PROM. Note that the type of PROM device

depends on what model CPU you have and how it is equipped.

■ If you are using a 340 or higher CPU (such as a CPU350, CPU351, etc.), read the next section

for an additional requirement.

Operation Without a Memory Backup Battery Using a 340 or Higher CPU

This information is applicable only to CPU model numbers 340 and higher (such as CPU350,

CPU351, etc.). In systems that do not use a memory backup battery, a standard 0.1” Berg jumper

should be installed across either of the two power supply battery connectors to ensure reliable

restarting of the CPU after a power cycle. This jumper should not be installed if a battery is

plugged into either the power supply or CPU battery connector.

Determining Battery Age Using Battery Date Code

Battery age can be determined from the date code stamped on the battery.

The battery, manufactured by Panasonic, will have a four-digit date code. It will be something like

5615 or 7Y34. Use the following information to determine the date of manufacture.

■ First digit shows the year in a rotating 10-year cycle. For example, 0=1990, 1=1991, 2=1992

... 9=1999, 0=2000, 1=2001, 2=2002, etc. This seeming duplication should not be a problem

because the shelf life of these batteries is 5 years. Batteries in inventory that are older than 4

years old should be discarded according to the manufacturer’s instructions (since they have

less than one year of life remaining we would not recommend using them in a PLC). This will

ensure that outdated batteries are not mistaken for newer batteries.

■ Second digit shows the month. 1=January, 2=February, 3=March, 4=April, 5=May, 6=June,

7=July, 8=August, 9=September, O=October, Y=November, Z=December.

■ Third digit shows the week of the month.

■ Fourth digit shows the day of the week. 1=Monday, 2=Tuesday, 3=Wednesday, 4=Thursday,

5=Friday, 6=Saturday, 7=Sunday.

For example, the code 7612 is interpreted as:

Manufactured on June 3, 1997

Chapter 6 Memory Backup/Battery Backup

RAM Memory Battery Backup Connection Path

CMOS RAM and DRAM memory is a volatile type of memory, which means that it can lose its

contents (ladder program, configuration, etc.) if power is removed. To retain RAM memory

contents under no-power conditions, a long-life lithium battery is provided. This battery is

normally mounted in the rack’s Power Supply module. To avoid accidental disconnection of the

memory backup battery, it is beneficial to know the connection path between the battery and the

memory circuits:

For embedded CPUs: The battery connection path to RAM memory is through the Power

Supply’s baseplate connector and across the backplane board to the RAM circuits.

For modular CPUs: The battery connection path to RAM memory is through the Power Supply’s

baseplate connector, across the backplane board, and through the CPUs baseplate connector to the

RAM circuits inside the CPU module.

Obviously, removing the Power Supply module from the PLC breaks the connection between the

backup battery and the RAM memory circuits for both embedded and modular CPUs. Also, in a

modular CPU system, removing the CPU module would disconnect the backup battery from the

memory circuits. In addition, to avoid the possible problems associated with losing the contents

of RAM memory, we recommend that you maintain an up-to-date backup copy of your program

folder. Instructions for creating program folder backups can be found in the Logicmaster 90,

Series 90-30 Programming Software User’s Manual, GFK-0466, and the online help and user’s

guides for the Windows-based programming software products.

Super Capacitor Memory Backup

Besides the backup battery, the RAM memory circuits in both Embedded and Modular CPUs are

further protected by a ”super capacitor,” which can store enough charge to maintain memory for a

short time if the battery is disconnected. The amount of protection time provided by the super

capacitor depends on the following:

■ The PLC power supply supplies 5 VDC to the memory circuits, including the super capacitor.

Therefore, when PLC power is turned off, the super capacitor has an initial 5 VDC charge. If

the battery is also disconnected shortly after PLC power is turned off, the super capacitor will

begin discharging from the 5 VDC level until its charge reaches 2 VDC, at which time

memory contents will be lost. When used this way, the super capacitor can maintain memory

contents for a minimum of 1 hour.

■ The memory backup battery supplies 3 VDC to the memory circuits, including the super

capacitor. Therefore, if PLC power has been turned off for an hour or more and only the

battery is powering the memory circuits, the super capacitor has a 3 VDC charge. Then, if the

battery is disconnected, the super capacitor will begin discharging from the 3VDC level until

its charge reaches 2 VDC, at which time memory contents will be lost. When used this way,

the super capacitor can maintain memory contents for a minimum of 20 minutes.

Maintaining RAM Memory During Storage or Shipment of a CPU

Modular CPUs

Modular CPUs have an internal connector for a backup battery so that RAM memory contents can

be retained while the CPU is being stored or shipped. This arrangement should not to be used

when the CPU module is installed in the baseplate and the backup battery is installed in the power

supply. To use a backup battery in the CPU module, it is necessary to remove the front cover of

the CPU module. This can be accomplished by following these steps:

■ To avoid losing memory contents once the CPU is removed from the PLC, we recommend you

install the backup battery into the CPU within 20 minutes. First, make sure PLC power is off,

then remove the CPU module.

■ Gently squeeze the front cover of the CPU module and pull it forward, away from the module

case, while gently pressing in on the 4 front cover tabs sequentially with a small screwdriver.

The front cover tabs latch into holes on each side of the module case (refer to Figure 2-1 for

location of front cover holding tabs).

■ After removing the front cover, plug the memory backup battery into the two-prong battery

connector on the front of the CPU module’s printed circuit board.

■ While the battery is connected to the CPU, you will have to leave the CPU’s front cover off.

Also, the battery should be temporarily secured to the module with cable ties or tape to keep it

from being accidentally damaged or disconnected.

The Battery Accessory Kit, described below, may also be used on a Modular CPU baseplate if the

power supply has to be removed. This would require leaving the CPU module mounted in the

baseplate.

Long-term battery backup can be provided with the use of the External Battery Module, described

on page 6-10.

Embedded CPUs

Embedded CPU Models 311, 313, and 323 can be stored or shipped with a power supply installed

and the power supply battery connected in order to maintain the contents of RAM memory.

However, another option (that doesn’t require the use of a power supply) is to use the Battery

Accessory Kit, described next.

Battery Accessory Kit (IC693ACC315)

The Battery Accessory Kit (IC693ACC315) lets you maintain RAM memory contents without

using a power supply. It is useful for maintaining memory contents while a baseplate is being

stored or shipped. The Battery Accessory Kit consists of a battery with an attached connector

mounted on a circuit board. The circuit board has a connector that plugs into the power supply

backplane connector (see the figure below). The Battery Accessory Kit can be used on either

Embedded or Modular Series 90-30 CPU baseplates.

Figure 6-2. Installing the Battery Accessory Kit

Battery Accessory Kit Installation

1. Insert the plug on the end of the battery cable into the 2-pin connector on the Battery Accessory

board. The battery plug is normally not plugged into the accessory connector. This prevents

accidental discharge of the battery during storage and handling.

2. Align the backplane connector on the Battery Accessory board with the power supply

connector on the baseplate backplane. Push the Battery Accessory board toward the baseplate

until it is fully seated. See the figure above.

3. If the baseplate is to be shipped with the Battery Accessory board installed, ensure that the

board is held in place by packing material or cable ties. The cable ties can be installed in holes

provided on both ends of the accessory board and secured to the baseplate.

Caution

To avoid losing CPU data, the Battery Accessory must be installed within 1

hour after turning off PLC power, or 20 minutes after removing the memory

backup battery. See “Super Capacitor Memory Backup” for details.

When the Battery Accessory is removed, a power supply module with a good

battery must be installed and/or input power applied within 20 minutes to

avoid losing CPU data. See “Super Capacitor Memory Backup” for details.

External Battery Module (IC693ACC302)

This module provides long-term battery backup for all modular Series 90-30 CPUs. Its two-foot

cable plugs into the power supply battery connector. The External Battery Module maintains RAM

contents on a CPU374 for 15 months. CPU models 331—364 maintain RAM contents for

approximately 75 months. For details, see the Datasheet for the External Battery Module,

Input/Output Modules

The basics of the Series 90-30 Input and Output (I/O) modules are covered in this chapter for your

convenience. A table listing these modules is located at the end of this chapter. For detailed

specifications and installation instructions, please refer to publication GFK-0898, Series 90-30 PLC

I/O Module Specifications.

Basic I/O Module Types

■

Discrete Input

Series 90-30 discrete input modules convert AC and DC power levels from user devices to the

logic levels required by the PLC. An optical coupler provides isolation between the incoming

power and the logic circuitry. Discrete input modules with 8, 16, or 32 points are available.

■

Discrete Output

Series 90-30 discrete output modules convert logic levels into AC or DC power levels required

for driving user supplied devices. Either a power semiconductor or an electromagnetic relay

switches each output point. The discrete output semiconductor-switched modules are available

with 5, 8, 12, 16, or 32 output points. Relay output modules are available with either 8 or 16

Normally Open relay contact outputs.

■

Discrete Input/Output

Combination discrete input/output modules combine AC inputs and relay outputs or DC

inputs and relay outputs on one module. Each of these modules have 8 input circuits and 8

relay output circuits on one board.

■

Analog Input

Series 90-30 analog input modules provide A/D (Analog to Digital) conversion by converting

an analog input signal into a scaled digital number which will be transferred into the PLC’s

%AI memory. Analog input modules are provided in four versions, (1) a 4-channel current

module, (2) a 4-channel voltage module, (3) a 16-channel high-density current input module,

and (4) a 16-channel high-density voltage input module.

■

Analog Output

Series 90-30 analog output modules provide D/A (Digital to Analog) conversion by converting

a scaled digital number (from the PLC’s %AQ memory) into an analog output voltage. Analog

GFK-0356Q

output modules are provided in three versions, (1) a 2-channel current module, (2) a 2-channel

voltage module, and (3) a high-density current/voltage module with 8 analog output channels.

■ Analog Combination Module

An analog combination module provides four A/D input channels and two D/A output

channels on one module. Each of the input and output channels can be configured individually

for current or voltage mode.

■ Third-Party Modules

In addition to the modules discussed in this chapter, numerous third-party I/O modules (and

other hardware and software products) for the Series 90-30 PLC are available to meet a wide

variety of needs. For information on third-party modules, consult the following:

Your GE Fanuc PLC distributor or sales engineer

Discrete I/O Modules

Discrete I/O Module Point Density

There are two density categories for these modules:

■ Standard Density Modules: Standard density modules have up to 16 circuits (also called

“points”) per module. These modules are equipped with a removable terminal board. See the

following figure.

■ High Density Modules: High density modules have 32 circuits per module. These modules

have either a 50-pin connector, or two 24-pin connectors mounted on their faceplates.

Connection choices are discussed later in this chapter.

Standard Density Discrete I/O Module Features

Standard Density(16 points or less) Modules have the following features (refer to the following

figure):

■ Removable Terminal Board. You can remove the terminal board from the module in order

to wire it, if desired. Then, when you are finished wiring it, you can easily reinstall it on the

module. However, some prefer to leave it on the module when wiring. If you ever need to

replace a module, you don’t have to do any rewiring if your old terminal board is still in good

condition. Simply remove the wired terminal board from the old module and install it on the

new module. The terminal board screw terminals are also convenient points for measuring

voltages while testing or troubleshooting.

■ Hinged Front Cover. The cover is easily opened to access the terminal board connections.

Normally it’s kept closed to protect personnel from accidentally touching a hot terminal. Note

in the following figure that the back side of the front cover insert contains a schematic diagram

of the terminal board connections. The module catalog number (IC693MDL940 in the

example shown) is printed on the bottom of the front cover insert. The module catalog

7-2

number is also printed on the label on the side of the module. However, in order to see this

side label, the module has to be removed from the PLC

On the front side of the front cover insert are lines that correspond to the module’s I/O points.

You can temporarily remove the insert and write the signal name for each point on the

appropriate line, as shown in the example in the figure.

Also on the front side of the front cover insert, running vertically on the left edge of the insert,

is a color bar that identifies the type of module: Blue = DC, Red = AC, and Gray = Analog.

■

Module Lens Cap. Located on the top front of the module, it covers the LED (Light Emitting

Diode) status lights . These are labeled in the following figure in two groups, A1 through A8,

and B1 through B8. Since this is a figure of a 16-Point Output module, there are 16 LED

status lights.

(The number of status lights on any given module is a function of the number of

circuits points on that module.) If you compare these status lights to the connection diagram

on the back of the hinged cover, you will notice that the outputs on this module are in two

groups, labeled A1-A8 and B1-B8, that correspond to the A and B rows of status LEDs. Note

the additional LED on the right side of the lens cap that is labeled with the letter F. This is a

blown fuse indicator light. This letter F is present on all of the discrete I/O module lens caps,

but is only functional on certain Output Modules that have internal fuses. It only lights if an

internal fuse is blown. A table with a list of modules having fuses as well as other details

about the status LEDs is provided in Chapter 13 of this manual.

Wiring Standard Density (16-Point or Less) Discrete Modules

There are three basic wiring methods:

■ Direct Method. Run the wires from the field devices (switches, relays, etc.) directly to the

screws on the modules’ terminal boards.

■ Terminal Strip Method. Mount a terminal strip inside the control enclosure and wire from

the terminal strip to the modules’ terminal boards. Then wire field devices to the terminal

strip.

■ Terminal Block Quick Connect Assembly Method. The Terminal Block Quick Connect

Assembly has three pieces: a faceplate, a cable, and a terminal block. The faceplate snaps onto

an I/O module in place of its normal terminal board. This faceplate has a connector that mates

with the cable. In turn, the cable plugs into a connector on the terminal block. The terminal

block mounts on a DIN-rail in a convenient place in your enclosure. The terminal block is

used for connecting to field devices such as switches and relays. This method saves, on the

average, over two hours of wiring time per module when compared with the Terminal Strip

method. For more information, see Appendix J, “Terminal Block Quick Connect

Components.”

Discrete Relay Output Module Protection

Output points on discrete relay output modules that switch an inductive load such as a relay coil,

lamp filament, or solenoid coil should have external protection. This is usually in the form of an R-

C (Resistor-Capacitor) network across an AC load, or a reverse-biased diode across a DC load.

Please see GFK-0898, Series 90-30 PLC I/O Module Specifications, for details.

High Density (32-Point) Discrete Module Features

■ There are two types of these modules. One type has a single 50-pin connector on its faceplate,

the other type has a pair of 24-pin connectors on its faceplate (see next two figures).

■ The dual 24-pin type has LED status indicators. The 50-pin type does not. The LED status

indicators are arranged in four groups of eight across, labeled A, B, C, and D. They are

located at the top of the module (see next figure).

■

32-point modules are only available in 5, 12, and 24 VDC ratings.

■ None of the 32-point modules are fused.

■ These modules are useful in applications where a high count of DC I/O points is required. The

maximum number of I/O points for a Series 90-30 system can be obtained by using a CPU that

supports a total of eight 10-slot racks, and by populating the racks with 32-point modules. The

theoretical maximum number of I/O points possible is calculated by adding the nine available

slots in the CPU rack (the CPU must occupy one slot) to the 70 slots in the seven 10-slot

expansion or remote racks to get a total of 79 slots. Multiply 79 times 32 for a maximum of

2,528 I/O points (only CPUs 350 - 364 support this many I/O points). This assumes that every

slot is populated with a 32-point I/O module. Most practical applications require some slots

for option modules, reducing the number of slots available for I/O modules accordingly.

Wiring Methods for 32-Point Discrete I/O Modules

Modules with Single 50-Pin Connector

Three choices are available for connecting these modules.

■ Connect to a Weidmuller #912263 terminal block using one of the two GE Fanuc “extension”

cables (see next figure). Cable IC693CBL306 is 3 feet (1meter) long. Cable IC693CBL307 is

6 feet (2 meters) long. Chapter 10, “Cables,” has details on these cables.

■ Connect to a user-supplied terminal block/strip or I/O field devices using one of the two GE

Fanuc “interface” cables. These cables have a 50-pin connector on one end that plugs into the

module, and stripped, tinned leads on the other for wiring to a terminal block/strip or I/O field

devices. Cable IC693CBL308 is 3 feet (1 meter) long, and cable IC693CBL309 is 6 feet (2

meters) long. These cables are useful if you have to run your wiring through conduit that is

too small for a connector to fit through.

■ Build a custom length cable. This is required if you need a cable longer than 6 feet (2 meters).

See the IC693CBL308/309 data sheet in Chapter 10 for pin-out details.

Modules with Dual 24-Pin Connectors

Three choices are available for connecting these modules

■ Connect to a pair of Terminal Block Quick Connect (TBQC) terminal blocks (IC693ACC337)

using a pair of GE Fanuc cables. Three lengths of cables are available: 20” (0.5 meter), 3 feet

(1 meter), 6 feet (2 meters). The cables come in right hand and left hand types because the

connectors on the modules are oriented differently (see figure 7-2). For details on the terminal

blocks and cables, please see Appendix J.

■ Connect to user supplied terminal block/strip or directly to I/O field devices using a pair of 10

foot (3 meter) GE Fanuc interface cables. These cables have 24-pin connectors on one end for

connecting to the module, and stripped, tinned leads on the other for wiring to a terminal

block/strip or I/O devices. Cable IC693CBL327 is for the left side and IC693CBL328 is for

the right side. These cables are useful if you have to run your wiring through conduit that is

too small for a connector to fit through, or if you need a cable longer than six feet. Chapter 10,

“Cables,” has details on these cables.

■ Build a custom length cable. This is required if you need a cable longer than 10 feet (3

Wiring Methods for Analog Modules

Twisted, shielded instrumentation cable is strongly recommended for analog module input or

output signal connections. Proper grounding of the shield is also important. For maximum

electrical noise suppression, the cable shield should only be grounded at one end of the cable. For

Input modules, ground the end that is in the noisiest environment (which often is at the field device

end). For Output modules, ground at the module end. See GFK-0898, Series 90-30 PLC I/O

Module Specifications, for more shield grounding information.

Analog Input Module Wiring Methods

Correcting electrical noise problems can sometimes be a trial-and-error routine. However, in

general, it is generally best to ground the cable shield as close to the source of the noise as possible,

which is usually at the device end. In troubleshooting noise problems, sometimes it is beneficial to

experiment with the shield grounding point location. Remember, the cable shield should be

grounded at one end only. Also, it is best to keep the length of stripped cable leads as short as

possible to minimize the length of unshielded conductors that will be exposed to the noisy

environment. See the Series 90-30 PLC I/O Module Specifications Manual, GFK-0898 for

additional details.

■ Direct Method. Run a shielded cable from the field device (transducer, potentiometer, etc.)

directly to the module. Connect the conductors to the applicable screws on the module’s

terminal board. Ground the shield at the field device end, exposing a minimum amount of

conductor to the noisy environment. Do not connect the shield at the module end (insulate it

with shrink tubing).

■ Terminal Strip Method. Mount a terminal strip inside the control enclosure and run a

shielded cable from the terminal strip to the module’s terminal board terminals. Connect the

shield to the metal panel next to the terminal strip. Do not connect the shield at the module

end (insulate it with shrink tubing). Wire the field device to the terminal strip with a shielded

cable, grounding the shield at the device end only (insulate the other end of the shield with

shrink tubing). Also, keep the length of exposed leads at the terminal strip and device ends as

short as possible.

Note

TBQC - The Terminal Block Quick Connect Assembly is not recommended for

use with analog modules due to cable shielding requirements.

Analog Output Module Wiring

Each output should be connected using a good quality shielded wire with the shield grounded at the

module end only. See GFK-0898, Series 90-30 PLC I/O Module Specifications, for more

information.

I/O Module Power Supply Current Draw

These values are found in Chapter 12 of this manual, which discusses how to calculate power

supply loading. The information is also found in GFK-0898, Series 90-30 PLC I/O Module

Specifications.

I/O Module Wire Routing

To reduce noise coupling among PLC wires, it is recommended you keep electrically noisy wiring,

such as AC power wiring and Discrete Output Module wiring, physically separated from low-level

signal wiring such as connections to DC and Analog Input modules. This can be accomplished by

grouping separately, where practical, the following categories of wiring:

■ AC power wiring. This includes the AC input to the PLC power supply, as well as other AC

devices in the control cabinet.

■ Analog Input and Output Module wiring. This should also be shielded to further reduce

noise coupling.

■ Discrete Output Module wiring. These often switch inductive loads that produce noise

spikes when switched off.

■ DC Input Module wiring. Although suppressed internally, these low-level inputs should be

further protected against noise coupling by observing these wiring practices.

Grouping Modules to Keep Wires Segregated

If practical, grouping similar modules together in the PLC racks can help keep wiring segregated.

For example, one rack could contain only AC modules and a different rack only DC modules, with

further grouping in each rack by input and output types. For smaller systems, as an example, the

left end of a rack could contain Analog modules, the middle could contain DC modules, and the

right end could contain AC modules. Where AC or Output wiring bundles must pass near low-

level signal wiring bundles, avoid running them beside each other. Route them so that, if they have

to cross, they do so at a right angle. This will minimize coupling between them.

IC693CMM302 Enhanced Genius Communications Module (GCM+)

The Enhanced Genius Communications Module (GCM+), IC693CMM302, is an intelligent module

that provides automatic global data communications between a Series 90-30 PLC and up to 31

other devices on a Genius bus.

The GCM+ can be located in any standard Series 90-30 CPU baseplate, expansion baseplate, or

remote baseplate. However, for most efficient operation, it is recommended that the module be

installed in the CPU baseplate since the sweep impact time of the GCM+ module depends on the

model of PLC and the baseplate where it is located. Note: if a GCM module is present in a

system, GCM+ modules cannot be included in the system.

Multiple GCM+ modules can be installed in a Series 90-30 PLC system with each GCM+ having

its own Genius bus serving up to 31 additional devices on the bus. For example, this allows a

Series 90-30 PLC with three GCM+ modules to exchange global data with as many as 93 other

Genius devices automatically. In addition to basic global data exchange, the GCM+ module can be

used for various applications such as:

Data monitoring by a personal computer or an industrial computer.

Monitoring data from Genius I/O blocks (although it cannot control Genius I/O blocks).

Peer-to-peer communications among devices on the bus.

Master-slave communications among devices on the bus (emulates remote I/O).

The Genius bus connects to the terminal board on front of the GCM+ module.

IC693BEM331 Genius Bus Controller (GBC)

The Series 90-30 Genius Bus Controller (GBC), catalog number IC693BEM331, provides the

interface between a Series 90-30 PLC and a Genius I/O serial bus. The GBC receives and

transmits control data of up to 128 bytes for up to 31 devices on the Genius I/O bus. A Genius Bus

Controller can serve:

Genius blocks, which provide an interface to a wide range of discrete, analog, and special-

purpose field devices. Note that the GCM and GCM+ modules, described earlier, cannot

control Genius blocks.

Remote Drops, which consist of Series 90-70 I/O racks interfaced to the bus through Remote

I/O Scanner modules. Each of these drops can have any mix of Series 90-70 discrete and

analog I/O modules, providing up to 128 bytes of input data and 128 bytes of output data.

Field Control I/O Station, which consists of a Bus Interface Unit (BIU) and up to eight

additional Field Control modules. The BIU provides intelligent processing, I/O scanning, and

feature configuration for the I/O station.

Genius Hand-Held Monitor (HHM), which is a portable device that can also be permanently

mounted. The HHM provides a convenient operator interface for block setup, data monitoring,

and diagnostics.

Number of Genius Bus Controllers

Up to eight Genius Bus Controllers or Enhanced Genius Communications Modules can be included

in a Series 90-30 PLC system that has release 5.0 or later CPU firmware. A GBC cannot be

installed in a system with a GCM.

The I/O devices on a bus may be Genius I/O blocks, or standard Series 90-70 I/O modules in one or

more remote drops. The total number of I/O circuits that can be served by one Genius bus depends

on the types of I/O devices that are used and the memory available in the CPU.

Many Genius I/O blocks have both inputs and outputs on the same block. Blocks configured in the

programming software as having both inputs and outputs occupy the identical number of references

in both %I and %Q memory, regardless of the block’s software configuration. Unused references

cannot be assigned to other inputs or outputs, and should not be used in the application program.

Status LEDs

The LEDs on the front of the GBC indicate its operating status and should be on during normal

operation.

OK Shows the status of the GBC module. This LED turns on after power up diagnostics are
