I/O Module Support - CompactLogix 5370 L1 Controllers
The CompactLogix 5370 L1 controllers offer an embedded I/O module and the option of using 1734 POINT I/O
modules as local expansion modules.
The embedded I/O module provides the following:
• 16 sinking 24V DC digital input points
• 16 sourcing 24V DC digital output points
To use 1734 POINT I/O modules as local expansion modules, keep in mind the following:
• Local expansion modules must be installed in the same system as the CompactLogix 5370 L1 controller.
• The modules are installed to the right of the controller.
• The maximum number of local expansion modules available depends on the controller catalog of that system.
Table 4 lists the number of 1734 POINT I/O modules the CompactLogix 5370 L1 controllers support. Each I/O
module’s minimum RPI is 1.0 ms and can be changed by 0.5 ms increments.

CompactLogix Controllers Specifications
You can use up to the maximum number of 1734 POINT I/O modules with the CompactLogix 5370 L1 controllers listed
in Table 4, as long as the total current drawn by the embedded I/O and local expansion modules does not exceed both the
available POINTBus backplane current of 1 A and the field power current of 3 A.
Depending on your application’s configuration, you can use one of the following devices to make additional POINTBus
backplane current or field power current available:
• 1734-EP24DC POINT I/O Expansion Power Supply - An expansion power supply is installed between
embedded I/O modules and local expansion modules or between local expansion modules.
The expansion power supply breaks the available POINTBus backplane current between the modules to its left and
right. With the expansion power supply installed, the modules to its left can draw up to 1 A of POINTBus
backplane current and the modules to its right can draw as much current as that provided by the expansion power
supply.
Additionally, the expansion power supply breaks the available field power current between the modules to its left and
right. With the expansion power supply installed, the modules to its left can draw up to 3 A of field power current
and the modules to its right can draw as much field power current as allowed by the expansion power supply.
For more information on the 1734-EP24DC expansion power supply, see the POINT I/O 24V DC Expansion
Power Supply Installation Instructions, publication 1734-IN058.
• 1734-FPD POINT I/O Field Power Distributor Module - A field power distributor module can also be installed
between embedded I/O modules and local expansion modules or between local expansion modules.
The field power distributor module breaks the available field power current between the modules to its left and
right. With the field power distributor module installed, the modules to its left can draw up 3 A of field power
current, and the modules to its right can draw as much field power current as allowed by the field power distributor.
For more information on the 1734-FPD POINT I/O Field Power Distributor module, see the POINT I/O Field
Power Distributor Module Installation Instructions, publication 1734-IN059.
IMPORTANT
Remember, the field power distributor module changes only the level of field power current available in the system. The
module does not affect the level of POINTBus backplane current available.

CompactLogix 5370 L1 Controllers’ Local I/O Performance
The requested packet interval (RPI) defines the frequency at which the controller sends data to and receives data from I/O
modules. You set an RPI rate for each I/O module in your system.
CompactLogix 5370 L1 controllers always attempt to scan an I/O module at the configured RPI rate. For individual I/O
modules, a Module RPI Overlap minor fault occurs if there are enough I/O modules with RPI rates set too fast that they
cannot all be serviced in the allotted interval.
The specific configuration parameters for a system determine the impact on actual RPI rates. These configuration factors
can impact the effective scan frequency for any individual module:
• Rates at which other 1734 POINT I/O modules’ RPI rates are set
• Number of other 1734 POINT I/O modules in the system
• Types of other 1734 POINT I/O modules in the system
• Application user task priorities
In general, follow these guidelines when setting the RPI rates in a CompactLogix 5370 L1 control system:
• For digital modules:
– 1…2 modules can be scanned in 2 ms.
– 3…4 modules can be scanned in 4 ms.
– 5…8 modules can be scanned in 8 ms.
IMPORTANT
When considering digital I/O modules, remember that they can be the embedded I/O module on the controller or
1734 POINT I/O modules that are used as local expansion modules. Therefore, the consideration for using two modules can
be the embedded I/O module and a 1734 POINT I/O module or two 1734 POINT I/O modules.
• For specialty and analog modules (except 1734-485ASC modules):
– 1 module can be scanned at 20 ms.
– For each additional module, add 20 ms.
For example, if a CompactLogix 5370 L1 control system uses two analog modules, the module can be scanned in
40 ms.
• For 1734-485ASC modules, the total data size for all ASC modules determines the RPI rates:
– For total data size less than 20 bytes, each module can be scanned in 20 ms.
– For data size greater than 20 bytes, use the size value as the RPI.
For example, if the total data size is 40 bytes, each ASC module can be scanned in 40 ms.
You are not required to set individual 1734 POINT I/O modules’ RPI values to the values listed previously. For example, if
your application scans one or two modules, you do not have to use RPI rates of 2 ms. Remember, though, that higher RPI
rates result in scanning the data less frequently.
The RPI shows how quickly modules can be scanned, not how quickly an application can use the data. The RPI is
asynchronous to the program scan. Other factors, such as program execution duration, affect I/O throughput.

IMPORTANT
Remember the following when using the embedded I/O modules on CompactLogix 5370 L2 controllers:
• 1769-L24ER-QB1B controller - The digital input points and digital output points are on one embedded I/O module. Therefore,
the 1769-L24ER-QB1B controller is considered to have one embedded I/O module.
• 1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B controllers - The digital input points and digital output points are on one
embedded I/O module. The high-speed counter input output points, universal analog input points, and analog output points
are on another single embedded I/O module. Therefore, the 1769-L24ER-QBFC1B and 1769-L27ERM-QBFC1B controllers are
considered to have two embedded I/O modules.

Rockwell Automation Publication 1769-TD005I-EN-P - August 2014
CompactLogix Controllers Specifications
You configure an RPI rate for the embedded I/O modules to establish specific time intervals at which data is transmitted
between the controller and the embedded I/O modules. The embedded I/O modules’ available RPI range is 0.5…750.0 ms
and can be changed by 0.5 ms increments. The default setting is 20 ms.
To use 1769 Compact I/O modules as local expansion modules, keep in mind the following:
• Local expansion modules must be installed in the same system as the CompactLogix 5370 L2 controller.
• Local expansion modules are installed to the right of the embedded I/O modules.
• You must install a 1769-ECR Compact I/O end cap on the right side of control system. The end cap can be installed
on the right side of the embedded I/O modules or, if local expansion modules are used, on the right side of 1769
Compact I/O module.

CompactLogix 5370 L2 Controllers’ Local I/O Performance
The requested packet interval (RPI) defines the frequency at which the controller sends data to and receives data from I/O
modules. In the programming software, you set an RPI rate for each I/O module in your system, including embedded I/O
modules, local expansion modules, or distributed I/O modules over an EtherNet/IP network.
The CompactLogix 5370 L2 controllers always attempt to scan an I/O module at the configured RPI rate. The controller
scans distributed I/O modules at the configured RPI rates.
With embedded I/O modules and local expansion modules, however, some specific system configuration parameters
determine the actual rate at which the controller scans the modules. That is, the controller can be configured to scan an
I/O module at one rate, but actually scan the module at another rate.
For individual I/O modules, a Module RPI Overlap minor fault occurs if there is at least one I/O module that cannot be
serviced within its RPI time.
Rockwell Automation Publication 1769-TD005I-EN-P - August 2014

CompactLogix Controllers Specifications
The specific configuration parameters for a system determine the impact on actual RPI rates. These configuration factors
can impact the effective scan frequency for any individual embedded or local expansion module:
• Rates at which embedded I/O modules’ RPI values are set
• Number of embedded I/O modules that are used in the system
• Types of embedded I/O modules that are used in the system
• Rates at which 1769 Compact I/O modules’ RPI values are set
• Number of 1769 Compact I/O modules in the system
• Types of 1769 Compact I/O modules in the system
• Application user task priorities
Table 8 describes RPI rate guidelines.
Table 8 - RPI Rate Guidelines
Type of Module
Guidelines
Digital and analog (any mix)
The following guidelines apply:
• 1…2 modules can be scanned in 0.5 ms.
• 3…4 modules can be scanned in 1 ms.
• 5…6 modules can be scanned in 2 ms.
• Some input modules have a fixed 8 ms filter, so selecting a faster RPI has no effect.
Specialty
The following conditions apply:
• For every full-sized 1769-SDN module in the system, increase every other module's RPI by 2 ms.
• For every 1769-HSC module in the system, increase every other module's RPI by 1 ms.
• For every full-sized 1769-ASCII module system, increase every other module's RPI by 1 ms.
• For every 1769-SM2 module in the system, increase every other module's RPI by 2 ms.
For example, if the system includes four I/O modules that are configured with an RPI = 1 ms and you add a 1769-SDN module to the system,
increase the RPI value for all four I/O modules by 2 ms. Therefore, when the 1769-SDN module is added to the system, the four I/O modules use
an RPI = 3 ms.
If, in the same system, you add a second 1769-SDN module, the four I/O modules’ RPI value is increased to 5 ms.
IMPORTANT
When considering the number of I/O modules, remember that they can be the embedded I/O modules on the controller or 1769 Compact I/O modules that are
used as local expansion modules.
Therefore, the consideration for using modules can be any of the following system configurations:
• Only embedded I/O modules
• Only 1769 Compact I/O modules
• Some combination of embedded I/O modules and 1769 Compact I/O modules
You can set individual 1769 Compact I/O modules’ RPI rates higher than those listed in Table 8. The RPI shows how
quickly modules can be scanned, not how quickly an application can use the data. The RPI is asynchronous to the program
scan. Other factors, such as program execution duration, affect I/O throughput.

I/O Module Support - CompactLogix 5370 L3 Controllers
The CompactLogix 5370 L3 controllers offer local expansion modules that are installed across up to three banks of
modules. You must use 1769 Compact I/O modules with these controllers.
Remember the following when using I/O modules with the CompactLogix 5370 L3 controllers:
• The controller must be the leftmost module in the local bank of the system.
• The number of I/O modules that are supported in a controller system varies by controller catalog number.

• You can install I/O modules in as many as three banks, that is, the local bank and two additional banks.
• You can install as many as three I/O modules between the controller and power supply.
• You can install as many as eight I/O modules to the right of the power supply in the local bank or on both the left
and right sides of the power supply in additional banks.
• You must consider the controller’s and all I/O modules’ distance rating and current draw when designing you system.
• Systems with multiple banks can be installed vertically or horizontally.
• You must use expansion cables to connect banks in multi-bank systems.
• You must terminate the end of the last bank in a system.

CompactLogix Controllers Specifications
CompactLogix 5370 L3 Controllers’ Local I/O Performance
The requested packet interval (RPI) defines the frequency at which the controller sends data to and receives data from I/O
modules. In the programming software, you set an RPI rate for each I/O module in your system.
The CompactLogix 5370 L3 controllers always attempt to scan an I/O module at the configured RPI rate. If there is not
enough system bandwidth, that is, if other, higher priority tasks prevent the 1769 Compact I/O subsystem task from
completing before the next scheduled time for it to run again, an I/O Task Overlap minor fault occurs.
For individual I/O modules, a Module RPI Overlap minor fault occurs if there is at least one I/O module which cannot be
serviced within its RPI time.
The specific configuration parameters for a system determine the impact on actual RPI rates. These configuration factors
can impact the effective scan frequency for any individual module:
• Rates at which other 1769 Compact I/O modules’ RPI rates are set
• Number of other 1769 Compact I/O modules in the system
• Types of other 1769 Compact I/O modules in the system
• Application user task priorities
Table 18 - RPI Rate Guidelines
Type of Module
Guidelines
1769 Compact I/O digital and analog
(any mix) modules
The following guidelines apply:
• 1…2 modules can be scanned in 0.5 ms.
• 3…4 modules can be scanned in 1 ms.
• 5…30 modules can be scanned in 2 ms.
• Some input modules have a fixed 8 ms filter, so selecting a faster RPI has no effect.
1769 Compact I/O specialty modules
The following conditions apply:
• For every full-sized 1769-SDN module in the system, increase every other module's RPI by 2 ms.
• For every 1769-HSC module in the system, increase every other module's RPI by 1 ms.
• For every full-sized 1769-ASCII module system, increase every other module's RPI by 1 ms.
• For every 1769-SM2 module in the system, increase every other module's RPI by 2 ms.
For example, if there are four digital I/O modules in the system configured with an RPI = 1 ms and a 1769-SDN module is added to the system, increase the RPI
value for all four digital I/O modules by 2 ms. Therefore, when the 1769-SDN module is added to the system the four digital I/O modules use an RPI = 3 ms.
If, in the same system, you add a second 1769-SDN module, the four digital I/O modules’ RPI value is increased to 5 ms.
You can set individual 1769 Compact I/O modules’ RPI values higher than those listed in Table 18. For example, if your
application scans one or two modules, you do not have to use RPI values = 0.5 ms. You can set the RPI to a higher value,
such as 1.0 ms, if necessary. Remember, higher RPI values result in scanning the data less frequently.

The RPI is asynchronous to the program scan. Other factors, such as program execution duration, affect I/O throughput.

The requested packet interval (RPI) defines the frequency at which the controller sends and receives all I/O data on the
backplane. The default RPI is 5 ms. The combination of embedded I/O in the packaged controllers determines the fastest
RPI you can configure.

CompactLogix Controllers Specifications
1769-L3x Local I/O Performance
You can configure an individual RPI for each local 1769 Compact I/O module. The RPI defines the frequency at which
the controller sends and receives all I/O data on the backplane.
Type of Module
Guideline
Digital and analog (any mix)
• 1…4 modules can be scanned in 1 ms
• 5…30 modules can be scanned in 2 ms
• Some input modules have a fixed 8 ms filter, so selecting a faster RPI has no
effect
Specialty
• Full-sized 1769-SDN modules add 2 ms per module
• 1769-HSC modules add 1 ms per module
• Full-sized 1769-ASCII modules add 1 ms per module
You can always select an RPI that is slower than listed previously. These considerations show how fast modules can be
scanned—not how fast an application can use the data. The RPI is asynchronous to the program scan. Other factors, such
as program execution duration, affect I/O throughput.

CompactLogix Controllers Specifications
Compact GuardLogix Safety System
The Compact GuardLogix® controller is a 1768-L4xS CompactLogix controller that provides safety control to achieve
SIL 3/PLe according to ISO 13849. A major benefit of this system is that it’s still one project, safety, and standard together.
Application
Description
SIL 1, 2, 3
The Compact GuardLogix controller system is type-approved and certified for use in safety applications up to and
including SIL 3 according to IEC 61508, and applications up to and including PLe/Cat.4 according to ISO 13849-1. For
more information, see the following:
• GuardLogix Controllers Systems Safety Reference Manual, publication 1756-RM093
• Compact GuardLogix Controllers User Manual, publication 1768-UM002
• GuardLogix Safety Application Instruction Set Reference Manual, publication 1756-RM095
During development, safety and standard have the same rules. The following are allowed:
• Multiple programmers
• Online editing
• Forcing
Once the project is tested and ready for final validation, you apply the safety application signature and safety-lock the
application to set the safety task to a SIL 3 integrity level, which is then enforced by the GuardLogix controller. When
safety memory is locked and protected, the safety logic can't be modified and all safety functions operate with SIL 3
integrity. On the standard side of the GuardLogix controller, all functions operate like a regular Logix controller. Thus
online editing, forcing, and other activities are all allowed.
With this level of integration, safety memory can be read by standard logic and external devices, like HMIs or other
controllers, removing the need to condition safety memory for use elsewhere. The result is easy system-wide integration and
™
the ability to display safety status on displays or marquees. Use Guard I/O modules for field device connectivity. For
safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks. Multiple GuardLogix
controllers can share safety data for zone to zone interlocking, or one GuardLogix controller can use remote distributed
safety I/O between different cells/areas.

1768-L4x Local I/O Performance
Configure an individual RPI for each local 1769 Compact I/O module. Use the default RPI numbers that the
programming software automatically assigns or select faster RPI values as fast as 1 ms I/O module update times do not
affect overall 1768 bus performance:
• Use faster RPI values for time critical I/O without impacting overall 1769 Compact I/O performance.
• Use Immediate Output (IOT) instructions for further reduction in I/O module update times.

A non-EtherNet/IP controller requires a 1761-NET-ENI interface to connect to an EtherNet/IP network. This interface is only a messaging bridge.
In the CompactLogix system, use either a 1769-SDN scanner (control I/O and send/receive messages) or a 1761-NET-DNI interface (messaging bridge).
The CompactLogix 5370 L1 controllers cannot access a DeviceNet network and, therefore, cannot communicate with other controllers on a DeviceNet network.
The CompactLogix 5370 controllers do not have an embedded serial port. You must add external modules to communicate over an RS-232 (DF1) network.
The CompactLogix 5370 controllers do not have an embedded serial port. You must add external modules to communicate over a DH-485 network.
The Ethernet PLC-5 controller must be series C, firmware revision N.1 or later; series D, firmware revision E.1 or later; or series E, firmware revision D.1 or later.
The 1785-ENET Ethernet communication interface module must be series A, firmware revision D or later.
The PLC-5, SLC, and MicroLogix processors appear as I/O points to the Logix controller. Use the appropriate DeviceNet interface for the controller.
Use a 1747-L55x controller with OS501 or later.

A non-EtherNet/IP controller requires a 1761-NET-ENI interface to connect to an EtherNet/IP network. This interface is only a messaging bridge.
In the CompactLogix system, use either a 1769-SDN scanner (control I/O and send/receive messages) or a 1761-NET-DNI interface (messaging bridge).
The 1788-EN2DN does not support safety communication (CIP Safety).
Use a CIP generic MSG instruction to communicate with the 1203-FM1 SCANport module on a DIN rail that is remote to the controller. The remote DIN rail also requires a 1794-ACN15 or 1794-ACNR15
ControlNet adapter module.
(5) Use the generic module configuration to configure the 1203-CN1 module and a CIP generic MSG instruction to communicate with the module.

CompactLogix Controllers Specifications
Controller Connections
A CompactLogix system uses the connection types to establish communication links between devices:
• Controller-to-local I/O modules or local communication modules
• Controller-to-remote I/O or remote communication modules
• Controller-to-remote I/O (rack-optimized) modules
• Produced and consumed tags
• Messages
• Controller access by the programming software
• Controller access by RSLinx® Classic software for HMI or other applications
You indirectly determine the number of connections the controller uses by configuring the controller to communicate with
other devices in the system. The limit of connections can ultimately reside in the communication module you use for the
connection. If a message path routes through a communication module, the connection that is related to the message also
counts toward the connection limit of that communication module.
CompactLogix 5370 Controller Ethernet Node Limits and Connections
When designing a CompactLogix 5370 control system, you must consider the following:
• Maximum number of Ethernet nodes available for your controller’s project
• Connections
The controller that you select determines the number of Ethernet nodes available.

Memory Cards
Memory cards offer nonvolatile memory to store a user program and tag data on a controller. Through the programming
software, you can manually trigger the controller to save to or load from nonvolatile memory or configure the controller to
load from nonvolatile memory on powerup.
.
IMPORTANT
The 1769-L23x packaged CompactLogix controllers do not offer a nonvolatile memory option.
The CompactLogix 5370 controllers come with a 1784-SD1 Secure Digital (SD) card installed. You can order a 1784-SD2
SD card separately for additional nonvolatile memory with the CompactLogix 5370 controllers.
The 1768-L4x and 1769-L3x modular CompactLogix controllers offer a CompactFlash card as a nonvolatile memory
option. You install the CompactFlash card in a socket on the controller. Through the programming software, you can
manually trigger the controller to save to or load from nonvolatile memory or configure the controller to load from
nonvolatile memory on powerup.

1769 CompactLogix Batteries
The 1769-L23x and 1769-L3x controllers come with one 1769-BA lithium battery.
The 1768 controllers and the CompactLogix 5370 controllers do not require a battery. The controller uses internal
nonvolatile memory to store its program during shutdown. Energy that is stored in the system maintains controller power
long enough to store the program to internal nonvolatile memory, but not the external CompactFlash card nor SD card
respectively.
