Distributed Control Without Compromise

The distributed approach to control drastically
reduces field wiring and heightens performance
because the controller and I/O are placed close to
the machine or process. FlexLogix achieves dis-
tributed control without the compromises -- such
as reduced processing power and programming
capability -- common to other distributed control
solutions. Instead, the FlexLogix distributed control
platform combines these industry-leading elements:
• FlexLogix controllers, having the same powerful

control engine as the one found in the high-per-
formance ControlLogix platform

• RSLogix 5000 programming software, the

Microsoft Windows NT package shared by other
Logix Platforms controllers

• FLEX I/O, the compact, DIN-rail mounted I/O

system found in thousands of industrial applica-
tions

• NetLinx Rockwell Automation network architec-

ture, a complete set of network services and
communication over DeviceNet, ControlNet and
Ethernet

No other vendor offers such state-of-art control,
communications and I/O elements in a distributed
control package.

In the distributed architecture (top), each oven has its own FlexLogix system, each communi-

cating via a single network to other FlexLogix systems, while in the centralized architecture

(bottom) operation of the three ovens relies on a single controller .

Modularity means you have the ability to

precisely fit the system to your machine or

application. The FlexLogix controller and

FLEX I/O may be mounted vertically or

horizontally, and the I/O may be placed in a

continuous stack or in two segments. And

you can mount the system onto a standard

DIN rail or onto a wall or panel.

Why Distributed Control?

For twenty years, customers have increasingly seen the advantage of moving away from central-
ized control. In a centralized control architecture, a master controller scans for I/O data, result-
ing in a system that is communication intensive and vulnerable to failure. In contrast, in a dis-
tributed control architecture:
• I/O data is handled locally and transmitted only when an event occurs, creating a less commu-

nication intensive architecture

• Control does not depend on a master controller, creating an architecture less vulnerable to

failure

• Control resides close to the machinery to establish zone control, station control or line control

Rockwell Automation’s Logix Platforms offer users compatibility of control in a variety of formats. This compatibility
is achieved with an RSLogix 5000 programming environment and with the NetLinx open network architecture. The
RSLogix 5000 environment offers an easy-to-use IEC 1131-3 compliant interface, symbolic programming with struc-
tures and arrays for increased productivity, and an instruction set that serves sequential, motion, process and drives

applications. The NetLinx open
architecture includes such open
networks as Ethernet, ControlNet
and DeviceNet.

can use your personal computer to communi-

cate to any FlexLogix controller locally, or dis-

tributed across a network.

A Controller You Can Adjust To Fit

Your Application

The FlexLogix controller offers you the flexibility to:
• Choose the memory size your application requires
• Select the communications you want via communica-

tion cards and a built in rs-232 port

• Determine how much I/O you want to control and pick

the modules needed for the application, with room to
expand in the future

• Divide your application into tasks for structured, fast

program development

Step 1:
Determine the I/O Devices

Use a spreadsheet to record the amount and type of I/O devices the
FlexLogix system needs. Record the:

•

location of the device

•

number of points needed

•

appropriate catalog number

•

number of points available per module

•

number of modules

To determine the number of modules you need, divide the “number
of points needed” by the “I/O points per module.” For example:

For more information about FLEX I/O modules and how they operate,
see page 17.

Step 2:
Layout the System

Layout the system by determining the network configuration and
the placement of components in each location. Decide at this
time whether each location will have its own controller.

Use the FlexLogix system to distribute control among different
locations. You might want one central controller, such as a
ControlLogix controller, to coordinate your FlexLogix
controllers. If the FlexLogix controller uses remote I/O, place it
on its own ControlNet network. If you plan to share I/O, make
sure the I/O is on a network that each controller can access.

Each FlexLogix controller can support:

•

8 local I/O modules

•

8 extended-local I/O modules

•

16 remote I/O modules over ControlNet

Adding to the example in Step 1, Location A and Location B
each require a unique FlexLogix controller. Location A has more
I/O modules than the controller can support as local I/O, so
some I/O will be configured as remote I/O over ControlNet.

The extended-local I/O in Location A requires a 1794-FLA
extended-local adapter. The remote I/O in Location A requires
an appropriate ControlNet adapter for the type of I/O modules.
These are all FLEX I/O modules, so use a 1794-ACN15, -ACNR15
ControlNet adapter.

For more information about placing I/O modules, see page 23.

You also need to evaluate what communications need to occur
between the controllers. For non-time critical information, use
the ControlNet network to send messages. If the information is
time critical, use produced/consumed tags between the
controllers over the ControlNet network.

controller supports 2 communication cards.

Location A requires one communication card to attach to ControlNet
network A and a second communication card to attach to ControlNet
network B. Add the communication modules to the spreadsheet:

Step 3:
Determine the Controller
Requirements

The following equations provide an estimate of the memory
needed for a controller. Each of these numbers includes a rough
estimate of the associated user programming. Depending on the
complexity of your application, you might need more or
less memory.

Step 5:
Select Power Supplies and
Ensure Sufficient Power

Create a spreadsheet to record your module selections and calculate
power requirements. Complete one spreadsheet for each rail of
components. For example:

Power Requirements for Location A, Local Rail

If your power consumption exceeds the maximums for a single power
supply, install additional power supplies or separate the I/O modules
onto multiple rails.

Step 6:
Verify Communications

The following table shows how many connections the controller
uses for these different communication configurations

For example, to calculate the connections for the example
controller in Location A, add the connections. Assume the
controller has these data transfer connections:

To calculate the number of connections for the modules in
Location A, add the connections required for:

•

modules on the local rail

•

modules on the extended-local rail

•

remote I/O modules

Connections for Location A, Local Rail

In this example, the controller uses one rack-optimized rack to control
the local I/O on the local rail.

Connections for Location A, Extended-Local Rail

In this example, the controller uses one rack-optimized rack to control
the local I/O on the extended-local rail. The controller also has direct
connections to the 1794-IB16 and 1794-OB16 I/O modules.

Regardless of how you configure the I/O modules on either the local
rail or the extended-local rail, the controller establishes a
rack-optimized connection for each rail.

Selecting FLEX I/O Modules

1794-SG001A-EN-P July 2000

Selecting FLEX I/O Modules

The FlexLogix system adds control to the flexible, low-cost,
modular FLEX I/O system. Use FlexLogix systems to meet the
needs of your distributed applications. The FlexLogix system
also lets you remove and insert I/O modules under power.

When planning I/O communications, consider:

FLEX I/O modules are packaged I/O modules that plug into
terminal bases. The terminal base makes the backplane and
provides the terminal connection points for wiring the I/O
module. The FlexLogix controller supports FLEX and FLEX Ex
I/O modules.

Considerations when planning I/O:

See page:

which FLEX I/O modules to use

where to place FLEX I/O modules

how FLEX I/O modules operate

This family of I/O modules:

Provides:

FLEX I/O

modular I/O

FLEX I/O builds an I/O interface onto a terminal strip. Use the terminal strip on the
terminal base to wire field devices directly.

FLEX Ex

intrinsically safe I/O

FLEX Ex adds intrinsic safety isolation to the modularity of FLEX I/O. Dual-fault,
intrinsically-safe circuits let you install I/O in a hazardous area while maintaining
high fault tolerance.

Do not mix regular FLEX I/O and FLEX Ex I/O on the same ControlNet
network segment.

Important:

If you use FLEX Ex I/O modules, make certain that you only
connect the intrinsically-safe I/O modules to other
intrinsically-safe system modules to maintain the integrity of
the intrinsically-safe system.

Selecting FLEX I/O Modules

Placing FLEX I/O Modules in a
FlexLogix System

The FlexLogix controller supports a local DIN rail of as many as
8 I/O modules and an extended-local DIN rail of as many as
8 I/O modules. The second DIN rail is optional.

When you create a project for a FlexLogix controller, the
Controller Organizer for that project automatically displays both
the local DIN rail and the extended DIN rail. If you do not use
the extended-local DIN rail, inhibit that rail.

You must configure an RPI rate for each DIN rail. This rate
applies to the I/O modules you install on the DIN rail.

If you have a mix of analog and digital I/O modules, place the
digital I/O modules on one DIN rail and place the analog I/O
modules on the second DIN rail. You can then configure a faster
RPI for the digital I/O and a more appropriate RPI for the analog
I/O without impacting the digital I/O. The fastest RPI possible
for a rail depends on the modules on that rail.

Planning Network Communications

Interfacing with communication networks is modular, except for
the RS-232 serial (DF1 protocol) port built into the FlexLogix
controller. Separate network communication cards are available
for interfacing the controller with ControlNet networks.

You determine your communication architecture based on your
networking needs. There are three main types of networks:

Information networks

An information network:

•

provides a link between the plant floor and the
manufacturing systems

•

connects to multiple vendor’s host computers

•

has the capacity to transfer large data files

•

supports standard network management and
troubleshooting tools

Control networks

A control network:

•

offers real-time performance

•

is deterministic and repeatable

•

supports peer-to-peer messaging

•

connects to programmable controllers, personal
computers, man-machine interface devices, drives, motion
devices, etc.

•

support programming and device configuration

Device networks

A device network:

•

reduces wiring costs because devices do not need to be
directly wired to a programmable controller

•

supports device-level diagnostics

•

connects to multiple vendors’ devices

A FlexLogix controller communicates across the DIN rail with
I/O modules on the local rail and on the extended-local rail. A

FlexLogix controller can also communicate through a communication
card to monitor and control I/O on ControlNet networks. General
communication messages can be sent from or received by FlexLogix
controllers across ControlNet and RS-232 serial networks.

The FlexLogix system is designed to control distributed applications,
not bridge data across networks. The FlexLogix controller supports
only one connected and one unconnected MSG to a device on
another network. Control performance degrades significantly if you
use the FlexLogix system as a bridge. Instead, use a
ControlLogix Gateway.

ControlNet Network

The ControlNet network is an open, high-speed, and
deterministic network used for transmitting time-critical
information. It provides real-time control and messaging services
for peer-to-peer communication. As a high-speed link between
controllers and I/O devices, a ControlNet network combines the
capabilities of existing Universal Remote I/O and DH+ networks.
You can connect a variety of devices to a ControlNet network,
including personal computers, controllers, operator interface
devices, drives, I/O modules, and other devices with ControlNet
connections.

At the control layer, a ControlNet network combines the
functionality of an I/O network and a peer-to-peer messaging
network. This open network provides the performance required
for critical control data, such as I/O updates and
controller-to-controller interlocking. ControlNet also supports
transfers of non-critical data, such as program uploads,
downloads, and messaging.

The 8-pin mini-DIN connector is not commercially available, so you cannot make this cable.

The 1756-CP3 cable attaches the controller directly to the RS-232 device.

If you make your own cable, it must be shielded and the shields must be tied to the metal shell
(that surrounds the pins) on both ends of the cable.

How the FlexLogix System
Uses Connections

The FlexLogix system uses a connection to establish a communication
link between two devices. This includes controllers, communication
modules, input/output modules, produced/consumed tags, and
messages. Connections take many forms:

•

controller direct to local I/O modules or local communication
daughtercards

•

controller direct to remote I/O or remote communication
modules

•

controller to remote I/O (rack optimized) modules

•

produced and consumed tags

•

messages

You indirectly determine the number of connections that the
controller requires by configuring the controller to communicate with
other devices in the system.

Each module in the FlexLogix system supports a limited number of
active connections. Take these connection limits into account when
designing your system. These modules support these number
of connections:

Use the following table to tally the connection requirements for
a controller:

Determining Connections for
Produced and Consumed Tags

The FlexLogix controller supports the ability to produce
(broadcast) and consume (receive) system-shared tags over a
ControlNet link. Produced and consumed data is accessible by
multiple controllers over a ControlNet network. Produced and
consumed data are scheduled connections because the
controller sends or receives data at a predetermined rate.

Produced and consumed tags must be controller-scoped tags of
DINT or REAL data type, or in an array or structure.

The producer and consumer must be configured correctly for
the specified data to be shared. A produced tag in the producer
must be specified exactly the same as the consumed tag in
the consumer.

Selecting a Controller

1794-SG001A-EN-P July 2000

Maximum number of produced and consumed tags

The maximum number of produced/consumed tags that you can
configure depends on the connection limits of the communication
device that transfers the produced/consumed data.

Determining Connections
for Messaging

Some messages use a connection to send or receive data. Some
messages also have the option of leaving the connection open (cache)
or closing the connection when the message is done transmitting. The
following table shows which messages use a connection and whether
or not you can cache the connection:

Message instructions that execute repeatedly should keep the
connection open to optimize execution time. Opening a connection

Determining Connections for
I/O Modules

For the FlexLogix controller to send or receive information from
I/O modules, a communication link, or connection, must be
established from the controller to the module. The controller
establishes a communication connection to an I/O module
either directly or indirectly by communicating to a
communication module in the system. A direct connection
occurs when the controller establishes a real-time, data-transfer
link directly with the module. A direct connection lets you tailor
the system to meet specific timing or information needs of
certain modules. Direct connections provide the greatest system
flexibility, but require extra system bandwidth and capacity.

In addition to direct connections, a communication module or
adapter can consolidate the data for multiple, digital I/O
modules, in the same chassis as the communication module,
into a single, rack-optimized connection. With a rack-optimized
connection, the controller establishes a single connection to a
communication module or adapter. The communication module
or adapter then establishes a connection to each of the
appropriate modules. By doing this, the communication module
or adapter reduces the:

•

number of message packets that must be sent on the
network

•

amount of processing time required by each module and
controller receiving the information

•

system communications overhead and capacity needs

•

number of connections used by the controller

The FlexLogix controller automatically assigns one
rack-optimized connection for the local DIN rail and one
rack-optimized connection for the extended-local DIN rail. You
then configure each I/O module on a DIN rail to either use that
rack-optimized connection or to use a direct connection. The
rack-optimized connection for each DIN rail exists whether or
not you configure the I/O modules to use that rack-optimized
connection.

The rack-optimized connection lets you organize all the digital
I/O modules on one DIN rail into one connection to the
controller. Or you can choose to configure each I/O module to
have a direct connection to the controller. Analog I/O modules
must have a direct connection to the controller.

Network Configuration
Software

RSNetWorx software for ControlNet (9357-CNETL3) is the
configuration and scheduling tool for your ControlNet network.
RSNetWorx software lets you create a graphical representation of
your network configuration and configure the parameters that
define your network.

RSNetWorx software also performs a scheduling function for all
network components. For example, each network scanner has
its own scan list and memory mapping. This information is
stored in the configurations files in the scanner. When changes
are made to the scan lists, RSNetWorx software automatically
calculates network bandwidth for the entire network, as well as
the bandwidth used by each network component.

You must have RSNetWorx software to configure and schedule
the ControlNet networks in your FlexLogix system.
