Baseplates

Baseplate Types

A baseplate is composed of three main parts: (1) a circuit board mounted to (2) a metal

back-plate with (3) a plastic cover. The circuit board, called the ”backplane,” contains

sockets for plug-in modules. The metal back-plate has four holes for mounting the

baseplate, and retainers for mounting the modules. The plastic cover provides

protection for the circuit board, slotted holes for the module connectors and retainers,

and printed labels such as the baseplate description, serial number, and slot number

labels. There are three basic types of baseplates discussed in this chapter:

Two Baseplate Sizes

Series 90-30 baseplates come in two sizes: 5-slot and 10-slot. Be aware that the Power

Supply slot is not numbered, and is not considered to be one of the 5 or 10 slots. So a

5-slot baseplate has slots for a Power Supply and five other modules, and a 10-slot

baseplate has slots for a Power Supply and ten other modules.

Baseplate Terms Explained

Backplane: Refers to the circuit board in the baseplate. It contains the baseplate

circuitry and sockets for the plug-in modules.

Rack: This term applies to an assembly consisting of a baseplate, power supply, and

other modules.

Rack Number: In systems that require more than one rack, each rack is given its own

unique number, which enables the CPU to distinguish one rack from another.

Slot Number: Each module location (called a ”slot”) on a baseplate has a unique

number (except for the unnumbered left slot which is for the Power Supply). The slot to

the right of the Power Supply slot is always called Slot 1. These slot numbers are marked

on the baseplate’s plastic cover. Each slot has a connector for module connections and

top and bottom retainers for holding the module in place.

Module Location: Since each rack is assigned a unique number, and since each slot in a

rack’s baseplate has a unique slot number, each individual module’s location in a system

can be identified by its rack and slot numbers. For example, a module could be referred

to as ”the module in Rack 1, Slot 4.” This numbering method enables the CPU to

correctly read from and write to a particular module, and report the location of a faulted

module.

CPU Baseplate: A baseplate that either has a CPU built-in to its backplane circuit board

(embedded CPU) or one that has a slot for a plug-in CPU module (modular CPU). There

can only be one CPU baseplate in a Series 90-30 PLC system and it will always be called

Rack 0 (zero). A CPU module can only mount in Slot 1 of a CPU baseplate. A special

Option module, such as the FIP Remote I/O Scanner module (IC693BEM330) can also be

used in Slot 1 of a CPU baseplate. I/O, Power Supply, and most Option modules cannot

fit in a CPU slot.

Expansion Baseplate: One that does not contain a CPU and which can be mounted up

to 50 cable-feet from the CPU baseplate. An Expansion baseplate cannot operate on its

own. It must be used in a system that has a controlling CPU.

Remote Baseplate: One that does not contain a CPU and which can be mounted up to

700 cable-feet from the CPU baseplate. A remote baseplate cannot operate on its own. It

must be used in a system that has a controlling CPU.

Power Supply Slot: Each baseplate must contain its own Power Supply module, which

must mount in the Power Supply slot. It is the slot located on the left end of the

baseplate, it is not numbered, and it has a unique size and shape so that only a Power

Supply module can mount in it.

Note

Attempts to force a module into an improper slot type will result in

damage to the module and/or the baseplate. Modules will mount in

the correct slot type easily and with a minimum of force.

CPU Baseplates

There are two basic kinds of CPU baseplates, embedded and modular. The embedded

types fulfill the need for a good low cost PLC, but lack the power, expandability, and

versatility of the modular systems.

Embedded CPU Baseplate: This type has CPU and memory integrated circuit chips

soldered to its backplane circuit board.

Modular CPU Baseplate: This type does not have CPU and memory chips on its

backplane. Instead, it has a connector in Slot 1 for a plug-in CPU module which contains

the CPU and memory chips on an internal circuit board.

Embedded CPU Baseplates (Figures 3-2 and 3-3)

There are three models of embedded baseplates, the 311, 313, and 323. These model

numbers are based upon the CPU type that each contains. This chapter discusses only

the baseplate features of these products. CPU specifications for the embedded CPU are

located in Chapter 4. The embedded CPU baseplates have the following features:

The CPU type cannot be changed.

They do not support the use of expansion or remote racks, so these racks do

not have an expansion connector like the modular CPU baseplates do.

The models 311 and 313 are 5-slot baseplates, and the model 323 is a 10-slot

baseplate.

Since they do not require a plug-in CPU module, all numbered slots,

including Slot 1, can be used for I/O or Option modules.

The memory back-up battery is located in the Power Supply module; so if

the Power Supply is unplugged from the baseplate, the battery will be

disconnected from the memory circuits, which are located on the backplane

circuit board. However, the backplane circuit board contains a high value

capacitor, sometimes called a ”super capacitor,” that can store enough charge

to maintain the memory circuits for about 1 hour if the Power Supply is

removed or its battery is disconnected. Chapter 6 discusses the

IC693ACC315 Battery Accessory kit that can be used to maintain memory

contents when the Power Supply is removed from an embedded CPU

baseplate.

There are no configuration switches or jumpers on the Model 311, 313, or

323 baseplates.

An embedded CPU baseplate is always assigned, by default, Rack Number

Zero (0).

Modular CPU Baseplates (Figures 3-4 and 3-5)

A Power Supply module must be plugged into the left slot (which is not

numbered) of these baseplates. The left slot is a unique size and type that

only supports a Power Supply module.

A CPU module (or a special Option module) must be installed in Slot 1 of

these baseplates. Slot 1 is a unique size and type that only supports a CPU

module or a special Option module like the FIP Remote I/O Scanner

(IC693BEM330). Slot 1 is labeled CPU/1.

Slots numbered 2 and above are of a unique size and type that only

supports I/O or Option modules.

Expansion and Remote baseplates are supported, so a 25-pin D-type female

expansion connector is located at the right end of the baseplate for

connecting to an Expansion or Remote baseplate.

Since the CPU is modular, it can be replaced or changed to a different type if

additional features are desired.

Only one CPU baseplate is allowed per system. If more than one baseplate

is used in a system, the additional ones must be either Expansion or Remote

types.

A modular CPU baseplate is always assigned, by default, Rack Number 0.

Expansion Baseplates (Figures 3-6 and 3-7)

There can be no more than a total of 50 feet (15 meters) of cable

interconnecting Expansion baseplates and the CPU baseplate.

An Expansion baseplate cannot stand alone. It must be connected to a

system that has a CPU. The CPU can be in a PLC or in a Personal Computer

that is equipped with a Personal Computer Interface Card (see Chapter 11).

Maximum number of Expansion baseplates allowed per system depends on

the type of CPU they are used with. For CPUs 331, 340, and 341, the

maximum is 4. For CPUs numbered 350 and higher, the maximum is 7.

Each Expansion baseplate has a 25-pin female D-type I/O Bus Expansion

connector mounted at its right end for connection to other baseplates.

Available in two versions; 5-slot (IC693CHS398) and 10-slot (IC693CHS392)

An Expansion backplane does not support the following intelligent option

modules: PCM, ADC, BEM330, and CMM. These modules must be mounted

in a CPU baseplate. All other I/O and option modules can be mounted in any

type of rack.

All Expansion baseplates must be connected to a common ground (see the

“Installation” chapter for details).

Expansion baseplates are the same physical size, use the same type power

supplies, and support the same I/O and option modules as the Remote

baseplates.

Each Expansion baseplate has a Rack Number Selection DIP switch.

Remote Baseplates (Figures 3-8 and 3-9)

There can be no more than 700 feet of cable connecting all baseplates in a

system that uses Remote baseplates.

A Remote baseplate cannot stand alone. It must be connected to a system

that has a CPU. The CPU can be in a PLC or in a Personal Computer that is

equipped with a Personal Computer Interface Card (see Chapter 11).

Remote capability is facilitated by the Remote baseplate’s built-in isolation

between the +5 volt logic supply used by the I/O modules residing in the

Remote baseplate and the supply for the interface circuit associated with the

I/O Bus Expansion Interface. Isolation helps prevent problems associated

with unbalanced ground conditions.

Maximum number of Remote baseplates allowed per system depends on

the type of CPU they are used with. For CPUs 331, 340, and 341, the

maximum is 4. For CPUs numbered 350 and higher, the maximum is 7.

Each remote baseplate has a 25-pin female D-type Expansion connector

mounted at its right end for connection to other baseplates.

Remote baseplates are available in two sizes; 5-slot (IC693CHS398) and 10-slot

(IC693CHS392)

A Remote backplane does not support the following intelligent option

modules: PCM, ADC, BEM330, and CMM. These modules must be mounted

in a CPU baseplate. All other I/O and option modules can be mounted in any

type of baseplate.

Remote baseplates are the same physical size, use the same type power

supplies, and support the same I/O and option modules as the Expansion

baseplates.

Each Remote baseplate has a Rack Number Selection DIP switch.

I/O Bus Expansion Cables

Five prewired I/O Bus Expansion cables are available from GE Fanuc. Catalog numbers and

lengths of these cables are listed in the following figure. You can build custom cables to suit

the needs of your application if cable lengths other than those listed are required. Refer to

the “Cables” chapter for detailed information on cable type and connectors. Note that the

same cables can be used with both Expansion and Remote baseplates, however the cables

used in a remote expansion system must use the cable type described in the “Cables”

chapter.

Differences Between Remote and Expansion Racks

Basically, Remote racks provide the same functionality as Expansion racks, but with the

longer distance (700 feet/213 meters verses 50 feet/15 meters for Expansion racks)

capability. To minimize unbalanced ground conditions, Remote baseplates have extra

3-12

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

GFK-0356P

isolation circuitry. Unbalanced ground conditions can occur when systems are located

long distances from each other and do not share the same ground system. However,

distance is not always the problem; even racks that are mounted near each other can

experience problems if the system is not grounded properly. See Chapter 2 for

grounding information.

The use of Remote racks requires a special consideration pertaining to scan time. In

order to operate at long distances, the I/O Bus runs at a lower clock speed (compared to

that used for Expansion racks) when communicating with Remote racks, which will

have an impact on performance. The impact will be relatively small for discrete I/O and

slightly more for other modules, such as the High Speed Counter or Genius

Communications Module. The increase in time needed to communicate with modules in

a remote baseplate will usually be small with respect to the overall scan time. For more

detailed information on scan time calculations, refer to Chapter 2 of GFK-0467, the Series

90-30/20/Micro PLC CPU Instruction Set Reference Manual.

Another important scan time consideration is the cable type used for communicating at

longer distances. Data propagation delay must be minimized to ensure proper system

timing and margins. Any deviation in cable type may result in erratic or improper

system operation. Suggested cable types are specified in the “Cables” chapter in the

IC693CBL300/etc. data sheet.

Mixing Expansion and Remote Baseplates in a System

Expansion and remote baseplates can be used in the same system as long as certain

requirements are met:

You do not exceed the 50 foot (15 meter) maximum cable distance from the

CPU to the last Expansion baseplate

You do not exceed the 700 foot (213 meter) maximum cable distance from

the CPU to the last Remote baseplate.

The cable type recommended for use with Remote baseplates must be used

throughout the system. The exception to this requirement is that the

prewired 3 foot (1 meter) cable, IC693CBL300, can be used as a Wye adapter

to simplify the custom cable assembly associated with the “daisy chain”

connections between baseplates. Information on building cables for use

with Remote baseplates can be found in the “Cables” chapter in the

IC693CBL300/etc. data sheet..

Termination Requirement for Expansion or Remote System

When two or more baseplates are connected via the I/O Bus Expansion System, the I/O

Expansion Bus must be properly terminated. The most common method of terminating

the I/O Expansion Bus is by installing a termination resistor pack (IC693ACC307) on the

open connector on the last (most distant from the CPU) Expansion or Remote baseplate

in the system. The resistor pack is physically mounted inside of a connector. Although a

termination resistor pack is shipped with each baseplate, only the last baseplate in the

chain needs to have this termination connector installed. Unused termination packs can

be discarded. The prewired 50 foot (15 meter) cable (IC693CBL302) has termination

resistors wired inside the connector on one end of the cable. This cable can be used if

only one expansion rack is needed in a system and a 50 foot cable link is required (the

IC693ACC307 resistor pack is not needed in this case). Also, a custom-built cable with

built-in resistors would eliminate the need for the IC693ACC307 resistor pack.

GFK-0356P

Chapter 3 Baseplates

3-13

Powering Down Individual Expansion or Remote Baseplates

Expansion or Remote baseplates can be powered-down individually without affecting the

operation of other baseplates; however, powering off a baseplate generates a loss of module

(LOSS_OF_MODULE) fault in the PLC Fault Table for each module in the baseplate. When

this fault condition occurs, and until the baseplate is powered back on and all modules

recovered, the lost I/O modules are not scanned. For more information on the power-up

and power-down sequence, see Chapter 2 in the Series 90-30 Programmable Controller

Reference Manual, GFK-0467.

Series 90-30 PLC Backplane

The Series 90-30 PLC backplane (on all three types of baseplates) has a dedicated I/O

communications bus. The signals on the remote baseplate backplane are optically coupled

and an isolated DC-DC power supply converter is provided to isolate the signals from other

backplanes.

Power bus - connects the power supply outputs to the modules in the

baseplate.

I/O Communications bus - the CPU communicates with I/O modules over

this bus. This bus is connected to the I/O busses in Expansion and Remote

racks via the I/O Bus Expansion connectors and cables.

Special Intelligent Module bus - exists only on a CPU baseplate; therefore,

certain special intelligent option modules, such as the PCM, ADC, and CMM

modules, will only work in a CPU baseplate.

Rack Number DIP Switch on Expansion and Remote Baseplates

Each baseplate in a Series 90-30 system is identified with a unique number called a “Rack

Number.” Rack Numbers for Expansion and Remote baseplates are selected by setting a

DIP switch located on each baseplate directly above the connector for Slot 1. Rack number

0 must always be present and is assigned, by default, to the CPU rack (the CPU baseplate

does not have this DIP switch). Racks do not need to be contiguously numbered, although

for consistency and clarity, it is recommended that rack numbers not be skipped (use 1, 2, 3 -

not 1, 3, 5). Rack numbers must not be duplicated within a system. The following table

shows the DIP switch positions for rack number selection.

The particular CPU module used determines how may expansion and remote baseplates

are allowed:

The 331, 340, and 341 CPUs support a total of 4 Expansion and/or Remote

racks.

The 350, 351, 352, 360, 363, and 364 CPUs support a total of 7 Expansion

and/or Remote racks.

Each baseplate has a label above the DIP switch that shows the settings for each rack

number. The following figure shows this DIP switch package with an example of rack

#2 number selected.

Note

Use a ball-point pen to set the DIP switches. In general, it is best to

avoid using a pencil to set DIP switches since graphite (a gritty,

conductive material) from the pencil can enter and damage the switch.

Baseplate Mounting Dimensions

Series 90-30 PLC baseplates are designed to be panel mounted. Each baseplate has

standard attachment flanges for mounting on an electrical panel. Baseplate dimensions

and proper spacing requirements for installation purposes for both the 5 and 10-slot

baseplates with embedded CPU (Models 311 and Model 313 are 5-slot baseplates; Model

323 is a 10-slot baseplate), and the 5 and 10-slot baseplates for Modular CPUs are shown

in figures 3-1 through 3-4.

Note

All 5-slot baseplates have the same mounting dimensions and all 10-slot

baseplates have the same mounting dimensions. Baseplates must be

mounted in the orientation as shown in the following figures for proper cooling.

operate from an input voltage source in the range of 85 to 264 VAC or 100 to 300 VDC.

This power supply provides the following outputs:

+ 5 VDC output.

+ 24 VDC ”Relay” power output which provides power to circuits on Series 90-30

Output Relay modules.

“Isolated” +24 VDC, which is used internally by some modules, can also be used to

provide external power for 24 VDC Input modules.

Field Wiring Connections for the AC/DC Input Power Supplies

The two AC/DC input power supplies have six terminals for user connections. These

connections are described below.

AC Power Source Connections

The Hot, Neutral, and Ground wires from the 120 VAC power source or L1, L2,

and Ground wires from the 240 VAC power source connect to the system

through the top three terminals of the terminal strip on the front of the power

supply.

DC Power Source Connections

Connect the + and - wires from the 125 VDC (nominal) power source to the

top two terminals on the terminal connector. These connections are not

polarity-sensitive on an AC/DC input power supply. (However, the DC

Input-only type supplies, which are discussed later in this chapter, are polarity

sensitive.)

Input Overvoltage Protection Devices

This information applies to all Series 90-30 power supplies except IC693PWR322

and IC693PWR328. The overvoltage protection devices for this power supply are

connected internally to pin 4 on the user terminal strip. This pin is normally

connected to frame ground (pin 3) with the supplied jumper strap which is

installed at the factory. If overvoltage protection is not required or is supplied

upstream, this feature can be disabled by removing the jumper strap from pins 3

and 4.

If you want to Hi-pot test this supply, overvoltage protection must be disabled

during the test by removing the terminal strip jumper strap. Re-enable

overvoltage protection after testing by reinstalling the strap.
