Logix Platforms
Allen-Bradley Logix platforms provide a single integrated control architecture for
discrete, drives, motion, and process control.
The Logix platforms provide a common control engine, programming software
environment, and communication support across multiple hardware platforms. All
Logix controllers operate with a multitasking, multiprocessing operating system and
support the same set of instructions in multiple programming languages. One
RSLogix™ 5000 programming software package programs all Logix controllers. And
all Logix controllers incorporate the NetLinx Open Network Architecture to
communicate via EtherNet/IP, ControlNet, and DeviceNet networks.

ControlLogix
System Overview
What’s New in Version 13:
y 1756-IB16ISOE and 1756-IH16ISOE modules
The ControlLogix® system provides sequential, process, motion, and drive control
together with communications and state-of-the-art I/O in a small, cost-competitive
package. The system is modular, so you can design, build, and modify it efficiently with significant savings in training and engineering. A simple ControlLogix system
consists of a stand-alone controller and I/O modules in a single chassis.
to record sequence of events
y 1756-IG16 and 1756-OG16 TTL I/O modules
y 1756-IA32 high-density, ac input module
y 1756-EWEB enhanced web server module
y 1756-M03SE 3-axes SERCOS module and
1756-L60M03SE controller with embedded
SERCOS interface
y 1756-M02AS SSI feedback motion module
y redundant controller systems now support
two 1756-L55 controllers or one
1756-L6x controller
y redundant controller systems now support
the 1756-ENBT module
y 1756-PSCA2 adapter module and 1756-CPR2
cable for redundant power supplies
1756-SG001G-EN-P — March 2004
Or use the ControlLogix system as a gateway. Include the communication modules you
need for connectivity to other networks. For this use, a controller is not required. The
ControlLogix Gateway integrates into existing PLC-based systems so that users with
existing networks can send or receive messages to or from other networks. For a
more robust system, use:
y multiple controllers in a single chassis
y multiple controllers joined across networks
y I/O in multiple platforms that is distributed in many locations and connected over
multiple I/O links
3
Layout the System
Lay out 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.
Place each controller’s I/O on an isolated network to maximize the performance and
to more easily accommodate future network or system configuration changes. If you
plan to share I/O, make sure the I/O is on a network that each controller can access.
Assume that Location A and Location B both require a controller and its own I/O.
Both controllers interact with time critical information. Panel C does not need a
controller and can be a gateway.
For a ControlLogix controller to control I/O modules, both the controller and the I/O
modules must be directly attached to the same network.

Evaluate what communications need to occur between controllers. If there is sporadic
information that is not time critical, use a message-based network such as an
EtherNet/IP (the information portion), Data Highway Plus, or the unscheduled portion
of a ControlNet network. If the information is time critical, such as
produced/consumed tags between controllers, use a ControlNet or EtherNet/IP
network.
1756-SG001G-EN-P — March 2004

Laying out a redundant system
The ControlLogix environment offers different levels of redundancy that you can
design into your system. These systems require additional hardware, so plan
accordingly. You can design redundant:
y media for ControlNet
y power supplies
y controller chassis
Redundant ControlNet media
Requires:
y 1756-CNBR ControlNet modules
y two identical ControlNet links
Redundant power supplies
Requires:
y two redundant power supplies, any combination of 1756-PA75R and 1756-PB75R
y 1756-PSCA2 chassis adapter module, in place of the standard power supply
y two 1756-CPR2 cables to connect the power supplies to the 1756-PSCA adapter
y user-supplied annunicator wiring to connect the power supplies to the input
modules, if needed
1756-SG001G-EN-P — March 2004
5
Redundant controller
chassis
Requires:
y one or two 1756-L55 controllers or one 1769-L6x controller in each redundant
chassis (contact your Rockwell Automation representative for the specific
firmware revision)
y at least one, but no more than five, 1756-CNB(R) series D, version 5.23 (or
greater) communication modules in each redundant chassis
y one 1757-SRM module in each redundant chassis
y the redundant chassis can contain a 1756-ENBT communication module, but no
other I/O or communication modules can be in the redundant chassis
All I/O must be remote from the redundant controllers. ControlLogix redundancy
works with remote 1756 I/O, FLEX I/O, drives, operator interfaces, or any other
devices that can communicate with a ControlLogix controller over a ControlNet link.
To connect to other networks, bridge through another ControlLogix chassis (not one
of the redundant controller chassis)

Step 1 - Select:
y I/O modules - some modules have field-side
diagnostics, electronic fusing, or
individually isolated inputs/outputs
Selecting ControlLogix
I/O Modules
y a remote terminal block (RTB) or wiring
system for each I/O module
y PanelConnect modules and cables if
connecting input modules to sensors
The ControlLogix architecture provides a wide range of input and output modules to
span many applications, from high-speed discrete to process control. The
ControlLogix architecture uses producer/consumer technology, which allows input
information and output status to be shared among multiple ControlLogix controllers.
Each ControlLogix I/O module mounts in a ControlLogix chassis and requires either
a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all
field-side wiring. RTBs and IFMs are not included with the I/O modules. They must be
ordered separately.
1756 Digital I/O
Modules
The 1756 digital I/O modules support:
y wide variety of voltage interface capabilities
y isolated and non-isolated module types
y point-level output fault states
y choice of direct-connect or rack-optimized communications
y field-side diagnostics on select modules
In addition, you can select these types of digital I/O modules:
Digital I/O Type

1756-CFM configurable flow meter
The 1756-CFM module provides totalizer mode for metering applications, or highspeed frequency measurements for speed or rate control applications, on two
channels connected to flowmeters. Both Fill and Prover functions are supported
within resettable or nonresettable totalizer mode. A 12-segment K-factor correction
table makes it easy to scale any turbine flowmeter and AGA 7 compensation is
available.
The module supports two configurable outputs that can be connected to one or both
channels and can be triggered on:
y flow or frequency
y acceleration
y full flow state
y trickle flow state
y prover run state
y prover range state
The module interfaces devices such as:
y magnetic pickup flow meters
y 4-40V dc pulses (TTL compatible)
y proximity probes

1756-HSC high speed counter
The 1756-HSC module provides 4 high-speed, output-switching, ON-OFF windows.
The module uses pulses for counting and frequency. The module interfaces with pulse
devices and encoders, such as:
y photoswitch series 10,000 photoelectric sensors
y bulletin 872 3-wire DC proximity sensors
y bulletin 845 incremental encoders
The 1756-HSC module can update data every 2ms. The module is most effective when
you use a single sensor for each of the two channels on the module. If necessary, you
can connect a single sensor to multiple channels or modules.

1756 Removable
Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your
plant wiring and 1756 I/O modules. The RTB plugs into the front of the I/O module.
The type of module determines which RTB you need. You choose screw-clamp or
spring-clamp RTBs.
RTBs are not shipped with I/O modules. You must order them separately. The
standard housing on the front of the wiring arm is not deep enough for 14 AWG
wiring. If you plan to use 14 AWG wiring, also order the extended housing.

As an alternative to buying RTBs and connecting the wires yourself, you can buy a
wiring system of:
y interface modules (IFMs) that mount on DIN rails provide the output terminal
blocks for the I/O module. Use the IFMs with the pre-wired cables that match the
I/O module to the interface module.
y I/O-module-ready cables. One end of the cable assembly is an RTB that plugs into
the front of the I/O module. The other end has individually color-coded conductors
that connect to a standard terminal block.

1492 PanelConnect
Modules for
Connecting Sensors
A PanelConnect module and its sensor connection systems lets you connect as many
as 16 sensors directly to 16-point input modules using convenient pre-built cables
and connectors.
The PanelConnect module mounts on the enclosure and creates the correct seal for
the entry of the sensor connections. You do not need to seal the opening where the
sensor cables enter the enclosure, create custom connectors, or wire to those custom
connectors.

Placing
ControlLogix I/O
Modules
If the I/O module is:
digital
The producer/consumer model multicasts messages. This means that multiple nodes
can consume the same data at the same time from a single device. Where you place
I/O modules in the control system determines how the modules exchange data.
And you place the module here:
local chassis
remote chassis
analog
The data exchange method is based on:
change of state
and / or
requested packet interval (cyclic)
requested packet interval
real time sample
and / or
requested packet interval
requested packet interval
local chassis
remote chassis
For a ControlLogix controller to control 1756 I/O, the I/O must be:
y in the same chassis as the controller or
y on a ControlNet network that is local to that controller or
y on an Ethernet/IP network that is local to that controller
For example, assume that the network links in this example are either ControlNet or
Ethernet/IP links. Both links can be the same, or one link can be a ControlNet link
and the other can be an Ethernet/IP link. Chassis A can control the 1756 I/O modules
in Chassis A and in Chassis B, but not in Chassis C. The ControlLogix controller in
Chassis A can only send messages to the devices in Chassis C.
Selecting Controller
Ownership
Relationship
owner controller
listen-only connection
In a Logix system, modules multicast data. This means that multiple devices can
receive the same data at the same time from a single device. When you choose a
communication format for an I/O module, you have to choose whether to establish an
owner or listen-only relationship with the module.
Description
The controller that creates the primary configuration and
communication connection to a module. The owner controller writes
configuration data and can establish a connection to the module.
An I/O connection where another controller owns/provides the
configuration data for the I/O module. A controller using a listen-only
connection only monitors the module. It does not write configuration
data and can only maintain a connection to the I/O module when the
owner controller is actively controlling the I/O module.

1756-SG001G-EN-P — March 2004
In a ControlLogix system, I/O updates occur asynchronous to the execution of logic.
This lets your application receive updated data as soon as possible. If your application
needs synchronous I/O updates, use the synchronous copy (CPS) instruction to buffer
I/O data at the beginning of each scan.
Operation
The RPI specifies the rate at which a module multicasts its data. The time ranges from 200
microseconds to 750 milliseconds. When the specified time frame elapses, the module will multicast
data (also called cyclic data exchange).
If a change of state (COS) does not occur within the RPI timeframe, the module multicasts data at the
rate specified by the RPI.
Because the RPI and COS functions are asynchronous to the logic scan, it is possible for an input to
change state during program scan execution. If this is a concern, buffer input data so your logic has a
stable copy of data during its scan. Use the Synchronous Copy (CPS) instruction to copy the input
data from your input tags to another structure and use the data from that structure.
The RPI and COS values still define when the module multicasts data within its own chassis, but only
the value of the RPI determines when the owner controller receives the data over the network.
When an RPI value is specified for an input module in a remote chassis, in addition to instructing the
module to multicast data within its own chassis, the RPI also reserves a spot in the stream of data
flowing across the control network. The timing of this reserved spot may or may not coincide with the
exact value of the RPI, but the owner-controller will receive data at least as often as the specified RPI.
If the module resides in the same chassis as the owner-controller, the module receives the data
almost immediately after the owner-controller sends it. Data is sent after all the programs within each
task have completed executing.
If an output module resides in a chassis other than that of the owner-controller (i.e. a remote chassis
connected via ControlNet or Ethernet/IP), the owner-controller sends data to the output module only
at the RPI rate.
The RPI also reserves a spot in the stream of data flowing across the control network. The timing of
this reserved spot may or may not coincide with the exact value of the RPI, but the output module
receives data at least as often as the specified RPI.
The RTS value specifies when the module scans its channels and multicasts the data (update the input
data buffer then multicast). The RPI value specifies when the module multicasts the current contents
of the input data buffer without scanning (updating) the channels.
The module resets the RPI timer each time an RTS transfer occurs. If the RTS value is less than or
equal to the RPI value, each multicast of data from the module has newly updated channel data. The
module only multicasts at the RTS rate.
If the RTS value is greater than the RPI, the module multicasts at both the RTS rate and the RPI rate.
The RPI and RTS rates still define when the module multicasts data within its own chassis, but only
the RPI value determines when the owner-controller receives the data over the network.
The RPI also reserves a spot in the stream of data flowing across the control network. The timing of
this reserved spot may or may not coincide with the exact value of the RPI, but the controller receives
data at least as often as the specified RPI.
The RPI value specifies when the owner-controller broadcasts output data to the module. If the
module resides in the same chassis as the owner-controller, the module receives the data almost
immediately after the owner-controller sends it.
If an output module resides in a chassis other than that of the owner-controller (i.e. a remote chassis
connected via ControlNet or Ethernet/IP), the owner-controller sends data to the output module only
at the RPI rate.
The RPI also reserves a spot in the stream of data flowing across the control network. The timing of
this reserved spot may or may not coincide with the exact value of the RPI, but the output module
receives data at least as often as the specified RPI.

The Logix approach to motion control employs synchronized, distributed processing
and provides a highly-integrated motion solution. Logix integrates sequential and
motion control to bring unmatched flexibility to machine design and unprecedented
efficiency to the manufacturing floor. RSLogix 5000 Enterprise series software
supports a comprehensive set of embedded motion instructions that can be
programmed using the relay ladder, structured text, or sequential function chart
editors. The embedded motion instructions satisfy a wide range of machine control
needs, including independent axis motion, synchronized gearing and camming, and
fully-interpolated motion in three dimensions.
The Logix architecture supports motion components that work in a wide variety of
machine architectures:
! The Kinetix integrated motion solution uses a SERCOS interface™ module to
perform complex, multi-axis, synchronized motion. With a Kinetix system, you reap
the full benefit of the integrated architecture because the integration doesn’t stop at
the controller. This system integrates the drive, the motor, and even the actuator at a
lower cost per axis of motion.
! Logix integrated motion using the analog family of servo modules for controlling
drives/actuators that do not support the SERCOS interface. The analog family of
servo modules provide a ±10 voltage analog output and can interface with a variety
of feedback device types including rotary/linear absolute and incremental.
! Networked motion provides the ability to connect via DeviceNet to a single-axis drive
to perform simple, point to point indexing. You need Ultraware™ software for drive
and indexing configuration.
Use this selection guide to select the appropriate motion interface. For more

Redundant controller systems via ControlNet
You can build a redundant controller system around a ControlNet network. In each
redundant controller chassis, you can have:
y one or two 1756-L55 controllers or one 1756-L6x controller in each
redundant chassis
y at least one, but no more than five, 1756-CNB(R) series D, version 5.23 (or
greater) communication modules in each redundant chassis
y one 1757-SRM module in each redundant chassis
y the redundant chassis can contain a 1756-ENBT communication module, but no
other I/O or communication modules can be in the redundant chassis
All I/O must be remote from the redundant controllers. ControlLogix redundancy
works with remote 1756 I/O, FLEX I/O, drives, operator interfaces, or any other
devices that can communicate with a ControlLogix controller over a ControlNet link.
To connect to other networks, bridge through another ControlLogix chassis (not one
of the redundant controller chassis)
The secondary controller is synchronized with the primary controller to provide a
bumpless switchover for any outputs controlled by logic in the highest priority task.
Switchover occurs within 100msec.

The RSLogix 5000 Enterprise Series software supports a generic ControlNet module
that allows connections to ControlNet nodes for which there is no specific support
currently available in the programming software. A module configured as a generic
ControlNet module communicates with the controller in the form of input, output,
status, and configuration tags. These tags and their characteristics vary depending on
the type of module.
For example, use the generic module configuration to set up communications between
a ControlLogix controller and a 1203-CN1 ControlNet communication module. Then
use the CIP generic MSG instruction type to send and receive messages from the
1203-CN1 module.

The DeviceNet network is an open low-level network that provides connections
between simple industrial devices (such as sensors and actuators) and higher-level
devices (such as PLC controllers and computers). The DeviceNet network uses the
proven Common Industrial Protocol (CIP) to provide the control, configure, and data
collection capabilities for industrial devices. The DeviceNet network is a flexible
network that works with devices from multiple vendors.

Use a 1756-CP3 cable to connect to the serial port.
Over the serial port, the ControlLogix controller supports 12 message buffers. At most,
you can have 4 simultaneous connected messages and 8 simultaneous unconnected
messages. Or if all the messages are unconnected, you can have 12 simultaneous
messages. If a message is greater than 250 bytes, it is divided across enough buffers to
carry the message, which reduces the number of buffers remaining for other
simultaneous messages.

DH-485 Network
On the DH-485 network, the controller can send and receive messages to and from
other controllers on the network. The DH-485 connection does support remote
programming and monitoring via RSLogix 5000 software. However, excess traffic over
a DH-485 connection can adversely affect overall performance and can lead to
timeouts and loss in RSLogix 5000 configuration performance.
Important: Only use Logix controllers on DH-485 networks when you want to add
controllers to an existing DH-485 network. For new applications with Logix
controllers, networks in the NetLinx architecture are the recommended networks.
You need a 1761-NET-AIC+ converter for each controller you want to put on the DH485 network. You can have two controllers per one 1761-NET-AIC+ converter, but
you need a different cable for each controller. Connect one controller to port 1 (9-pin
connector) and one controller to port 2 (mini-DIN connector).

The ControlLogix controller provides a scalable controller solution that is capable of
addressing a large amount of I/O points (128,000 digital maximum / 4000 analog
maximum).
The ControlLogix controller can be placed into any slot of a ControlLogix I/O chassis
and multiple controllers can be installed in the same chassis. Multiple controllers in
the same chassis communicate with each other over the backplane (just as controllers
can communicate over networks) but operate independently.
ControlLogix controllers can monitor and control I/O across the ControlLogix
backplane, as well as over I/O links. ControlLogix controllers can communicate with
computers or other processors across RS-232-C (DF1/DH-485 protocol), DeviceNet,
DH+, ControlNet, and EtherNet/IP networks. To provide communication for a
ControlLogix controller, install the appropriate communication interface module into
the chassis.
The multi-tasking operating system supports 32 configurable tasks that can be
prioritized. One task can be continuous. The others must be periodic or event tasks.
Each task can have as many as 32 programs, each with its own local data and logic,
allowing virtual machines to operate independently within the same controller.

§The 1756-L60M03SE is a 1756-L60 ControlLogix controller with an embedded 1756-M03SE SERCOS interface. This is a 2-slot module.
The 1756-L6x controller executes ladder scans almost twice as fast as the 1756-L55
controllers and executes function block, REAL data type math, and motion instructions
4-5 times faster than the 1756-L55 controllers.
The 1756-L60M03SE controller combines a 1756-L6x controller and a SERCOS
motion module in a two-slot module. This controller is ideal for small motion systems
and can control 3 SERCOS axes with the included interface. This controller can
control as many as 6 axes if you add an additional motion module.
Selecting a controller for a redundant
controller system
If you are designing a redundant controller system, consider:
y Redundant controller systems support one or two 1756-L55 controllers or one
1756-L6x controller in each redundant chassis.
y Data is buffered in the secondary controller, so twice as much data memory space is
required in the controller.
y The redundant controllers must be on a ControlNet network.

boards to come already assembled with the controller. You can also order additional
memory boards either for spare parts or to upgrade existing 1756-L55 controllers.
The 1756-L6x controllers have a fixed RAM size and do not use a memory board. Use
a CompactFlash card for nonvolatile storage. You must remove the controller from the

1756-L60M03SE controller requires firmware revision 13 or higher.
Non-volatile memory
The nonvolatile memory (flash) lets you permanently store a user program and tag
data on a controller. You can:
y manually trigger the controller to save to or load from nonvolatile memory
y configure the controller to load from nonvolatile memory on power up
The 1756-L55M2x controllers have fixed internal nonvolatile memory.
The 1756-L6x controllers support a removable CompactFlash card for nonvolatile
memory. You install the 1784-CF64 card in a socket in the controller. You must
remove the controller from the chassis to install CompactFlash. The CompactFlash
card stores the user program, tag data, and controller firmware. This lets you
upgrade firmware on a 1756-L6x controller without using RSLogix 5000 or
ControlFlash software.

How a Logix
System Uses Tasks
If you want to execute a section of your
logic:
all of the time
A Logix controller uses three types of tasks. Use the following table to choose the
appropriate type of task for each section of your logic.
Then use this type of task:
Continuous Task
y at a constant period (e.g., every
100 ms)
y multiple times within the scan Periodic Task.
of your other logic
immediately when an event occurs
Description:
The continuous task runs in the background. Any CPU time not
allocated to other operations (such as motion, communications, and
periodic or event tasks) is used to execute the programs within the
continuous task.
y The continuous task runs all the time. When the continuous task
completes a full scan, it restarts immediately.
y A project does not require a continuous task. If used, there can be
only one continuous task.
A periodic task performs a function at a specific period.
y Whenever the time for the periodic task expires, the task interrupts
any lower priority tasks, executes one time, and then returns
control to where the previous task left off.
y You can configure the time period from 0.1 ms to 2000 msec. The
default is 10 ms. It is also controller and configuration dependent.
y The performance of a periodic task depends on the type of Logix
controller and on the logic in the task.
An event task performs a function only when a specific event (trigger)
occurs.
The trigger for the event task can be:
y change of a digital input
y new sample of analog data
y certain motion operations
y consumed tag
y EVENT instruction
Event Task
Whenever the trigger for the event task occurs, the event task:
y interrupts any lower priority tasks
y executes one time
y returns control to where the previous task left off
Event tasks
Several factors affect the closed-loop event throughput:
y input module type, filter time, and response time
y backplane size and loading
y controller type, configuration, and loading
y output module type and response time
1756-SG001G-EN-P — March 2004

To use a device to trigger an event task, the device must support event task triggering.
If the device is in a remote location, the associated communication modules must
also support event triggering. These devices support input events:

Estimating event task throughput
To estimate the throughput time from input to output (screw to screw), use the
following worksheet:
Value (in µs):
Consideration:
1. What is the input filter time of the module that triggers the event task?
This is typically shown in milliseconds, Convert it to microseconds (µs).
2. What is the hardware response time for the input module that triggers the event task?
Make sure you use the appropriate type of transition (Off to On or On to Off). See the following table.
3. What is the backplane communication time?
If the chassis size is:
Use this value (worst case):
4 slot
13 µs
7 slot
22 µs
10 slot
32 µs
13 slot
42 µs
17 slot
54µs
4. What is the total execution time of the programs in the event task?
5. What is the backplane communication time (same value as step 3).
6. What is the hardware response time of the output module?
7. Add steps 1 through 6. This is the minimum estimated throughput, where execution of the motion planner or
other tasks do not delay or interrupt the event task.
8. What is the scan time of the motion group?
9. What is the total scan time of the tasks that have a higher priority than this event task (if any)?
10. Add steps 7 through 9. This is the nominal estimated throughput, where execution of the motion planner or
other tasks delay or interrupt the event task.
Use the following table to determine the nominal hardware response time for
selected 1756 I/O modules.

How a Logix
System Uses
Connections
A Logix system uses a connection to establish a communication link between two
devices. Connections can be:
y controller to local I/O modules or local communication modules
y controller to remote I/O or remote communication modules
y controller to remote I/O (rack optimized) modules
y produced and consumed tags
y messages
You indirectly determine the number of connections the controller uses by
configuring the controller to communicate with other devices in the system.
Connections are allocations of resources that provide more reliable communications
between devices than unconnected messages. A Logix system supports:
Method
scheduled connection
y level of determinism
y unique to ControlNet
unscheduled connection
y deterministic
y used by both ControlNet and EtherNet/IP
unconnected message
y least deterministic
Description
A scheduled connection is unique to ControlNet communications. A scheduled connection lets
you send and receive data repeatedly at a predetermined interval, which is the requested
packet interval (RPI). For example, a connection to an I/O module is a scheduled connection
because you repeatedly receive data from the module at a specified interval. Other scheduled
connections include connections to:
y communication devices
y produced/consumed tags
On a ControlNet network, you must use RSNetWorx for ControlNet to enable all scheduled
connections and establish a network update time (NUT).
An unscheduled connection is a message transfer between controllers that is triggered by the
requested packet interval (RPI) or the program (such as a MSG instruction). Unscheduled
messaging lets you send and receive data when needed.
All EtherNet/IP connections are unscheduled.
An unconnected message is a message that does not require connection resources. An
unconnected message is sent as a single request/response.
The communication module you select determines the number of connections you
have available for I/O and messages.
This communication module:
1756-CNB
1756-ENBT
Supports this number of connections:
64
(any combination of scheduled and unscheduled)
128
(any combination of scheduled and unscheduled)
The EtherNet/IP module does not distinguish between scheduled and
unscheduled connections.
How you configure connections determines how many remote devices a
communication card can support.
1756-SG001G-EN-P — March 2004
58
Determining
Connections for
Produced and
Consumed Tags
This type of tag:
produced
consumed
The controller supports the ability to produce (broadcast) and consume (receive)
system-shared tags over ControlNet or EtherNet/IP networks. Produced and consumed
tags each require connections. Over ControlNet, produced and consumed tags are
scheduled connections.
Requires these connections:
A produced tag allows other controllers to consume the tag, which means that a controller can receive the
tag data from another controller. The local controller (producing) uses one connection for the produced
tag and one connection for each consumer. The controller’s communication device uses one connection
for each consumer.
As you increase the number of controllers that can consume a produced tag, you also reduce the number
of connections the controller and communication device have available for other operations, like
communications and I/O.
Each consumed tag requires one connection for the controller that is consuming the tag. The controller’s
communication device uses one connection for each consumer.
For two controllers to share produced or consumed tags, both controllers must be
attached to the same control network (such as a ControlNet or Ethernet/IP network).
You cannot bridge produced and consumed tags over two networks.
The total number of tags that can be produced or consumed is limited by the number
of available connections. If the controller uses all of its connections for I/O and
communication devices, no connections are left for produced and consumed tags.
Maximum number of produced and
consumed tags
The controller supports:
As a:
The controller supports:
producer
consumer
(number of produced tags) ≤ 127
(number of consumed tags) ≤ 250
The total combined consumed and produced tags that a controller supports is (this
is also the maximum number of connections):
(number of produced tags) + (number of consumed tags) ≤ 250
1756-SG001G-EN-P — March 2004
59
Determining
Connections for
Messages
Messages transfer data to other devices, such as other controllers or operator
interfaces. Some messages use unscheduled connections to send or receive data.
These connected messages can leave the connection open (cache) or close 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:
This type of message:

9
✶You can connect CIP generic messages, but for most applications we recommend you leave CIP generic messages unconnected.
Connected messages are unscheduled connections on both ControlNet and
EtherNet/IP networks.
Each message uses one connection, regardless of how many devices are in the
message path. To conserve connections, you can configure one message to read from
or write to multiple devices.
If a message executes repeatedly, cache the connection. This keeps the connection
open and optimizes execution time. Opening a connection each time the message
executes increases execution time.
If a message executes infrequently, do not cache the connection. This closes the
connection upon completion of the message, which frees up that connection for other
uses.
A Logix system uses connections to transmit I/O data. These connections can be direct
connections or rack-optimized connections.
Determining
Connections for I/O
Modules
Connection
direct
rack-optimized
A Logix system uses connections to transmit I/O data. These connections can be direct
connections or rack-optimized connections.
Description
A direct connection is a real-time, data transfer link between the controller and an I/O
module. The controller maintains and monitors the connection between the controller and the
I/O module. Any break in the connection, such as a module fault or the removal of a module
while under power, causes the controller to set fault status bits in the data area associated with
the module.
Typically, analog I/O modules and specialty modules require direct connections.
For digital I/O modules, you can select rack optimized communication. A rack optimized
connection consolidates connection usage between the controller and all the digital I/O
modules on a rack (or DIN rail). Rather than having individual, direct connections for each
I/O module, there is one connection for the entire rack (or DIN rail).
1756-SG001G-EN-P — March 2004

Depending on the type of I/O modules, both direct connections and rack-optimized
connections can be used.

1756-SG001G-EN-P — March 2004
Details
The controller can have a direct connection to every I/O module in a remote chassis on an
EtherNet/IP or ControlNet network. Because all the remote I/O modules are configured for
direct connections, configure the remote communication module for “none,” which results in
no connection.
Rather than one connection to each remote I/O module, use one connection to communicate
with all the digital I/O in the remote chassis (each analog I/O module requires a direct
connection). The data from all the digital I/O modules is sent simultaneously at a rate specified
by the remote connection through the EtherNet/IP or ControlNet communication module.
The rack-optimized connection conserves connections and bandwidth. However, because the
connections are condensed into one rack connection, the optimized digital I/O can no longer
send all of its status and diagnostic data.
A remote ControlLogix chassis can have both a rack-optimized connection and direct
connections. Use a rack-optimized connection to consolidate all the digital I/O modules. Use a
direct connection for each analog I/O module.
The controller uses two connections to communicate with the 1756-DNB module. The 1756DNB module does not establish connections to its devices; and therefore, the controller
doesn’t establish connections with DeviceNet devices. The 1756-DNB module acts as a scanner
that gathers all the data from its devices and packs that data together into one image that is
passed to the controller. However, the controller can use a MSG instruction to get information
directly to or from a DeviceNet device.
The controller communicates with a 1771 chassis through a 1756-DHRIO module to the
adapter module of the 1771 chassis. The controller uses one connection for each logical rack.
The addressing mode (1/2 slot, 1 slot, or 2 slot) of the 1771 chassis determines the number
of logical racks, which determines the total number of connections. In addition, the controller
uses one connection for each message to a 1771 block-transfer module.

Determining Total
Connection
Requirements
The ControlLogix controller supports 250 connections. To calculate the total
connections for a controller, consider the connections to local I/O modules and the
connections to remote modules.
Use the following table to tally local connections:
Connection Type
Device Quantity
local I/O module (always a direct connection)
1756-M16SE, -M08SE, -M02AE servo module
1756-CNB, -CNBR communication module
1756-ENBT communication module
1756-DNET communication module
1756-DHRIO communication module

Regardless of how you configure local I/O modules (rack-optimized or direct
connect), the controller establishes a direct connection for each local I/O module.
Remote connections depend on the communication module. The number of
connections the module itself supports determines how many connections the
controller can access through that module. Use the following table to tally remote
connections for the controller:
Connection Type
remote 1756-CNB, -CNBR ControlNet communication module
configured as a direct (none) connection
configured as a rack-optimized connection
remote I/O module over ControlNet (direct connection)
remote 1756-ENBT Ethernet communication module
configured as a direct (none) connection

Selecting Chassis
Step 5 - Select:
y a chassis with sufficient slots
y 1756-N2 filler strips for empty slots
The ControlLogix system is a modular system that requires a 1756 I/O chassis to
contain the various modules. Chassis are available in sizes of 4, 7, 10, 13, and 17
module slots. You can place any module into any slot.
The backplane provides a high-speed communication path between modules. Multiple
controller modules on the backplane can pass messages between one another. With
multiple communication interface modules on the backplane, a message can be sent
from across a link into a port on one module, routed across the backplane and out
another module’s port, and sent across another link to its ultimate destination.

y a power supply bundle if you are planning a
redundant power supply system
ControlLogix power supplies are used with the 1756 chassis to provide 1.2V, 3.3V,
5V, and 24V dc power directly to the chassis backplane. Non-redundant (1756-PA72,
-PB72, -PA75, -PB75) and redundant (1756-PA75R, -PB75R) power supplies are
available.
Selecting a standard power supply
You mount a standard power supply directly on the left end of the chassis, where it
plugs directly into the backplane. The power supply you select can determine which
chassis you can use.

Power
Requirements and
Transformer Sizing
Each ac-input power supply generates a shutdown signal on the backplane whenever
the ac line voltage drops below its lower voltage limit. It removes the shutdown signal
when the line voltage comes back up to the lower voltage limit. This shutdown is
necessary to help ensure that only valid data is stored in memory.
The external transformer rating (in VA) of each power supply is greater than its real
input power (in Watts) because a capacitor-input ac/dc supply draws power only from
the peak of the ac voltage wave form. If the transformer is too small, it clips the peak
of the sine wave; when the voltage is still above the lower voltage limit, the power
supply will sense this clipped wave form as low voltage and could prematurely shut
down modules in the chassis.
The following graphs display the backplane power load on the vertical axis. Since
these supplies have multiple outputs, the backplane power load is given in watts.
y Use the real power value in watts for determining the amount of heat dissipation you
will have inside the enclosure.
y Use the apparent power value in VA for estimating power distribution sizing.
y Use the transformer load value in VA of each power supply plus all other loads on a
transformer to determine the required transformer size.
