CompactLogix 5000/5069 Selection Guide
Allen-Bradley CompactLogix (5069) systems consist of 5069 CompactLogix controllers and Compact 5069 I/O modules. These Logix platforms are compact in design with high-performance control capabilities. They are available with both standard I/O modules and safety options which provide faster safety reaction time. This makes the 5069 Logix system an ideal solution for control applications with high-processing requirements and considerable safety standards. For example, the Compact 5069 Safety I/O modules can be expanded to provide local safety I/O connectivity to the Compact GuardLogix 5380 controllers.
Also, CompactLogix 5069 systems provide distributed I/O control over an EtherNet/IP network, accessible to the CompactLogix 5380 controllers via EtherNet/IP adapters. Moreover, they provide enhanced diagnostics and troubleshooting information with controller status and fault display. A 5069 CompactLogix system would be the best choice if you’re looking for high-performance communications, multiple I/O options, and motion control of up to 150 axes.
Selection Criteria
When designing a CompactLogix (5069) system, there are many key components and features to consider, based on the application requirements. These key components and features include:
CompactLogix 5380 Controllers
CompactLogix 5069 platforms are compatible with CompactLogix 5380 controllers, which are part of the Logix 5000-series controllers. These controllers provide increased performance, productivity, capacity, and security to meet the growing demands for smart machinery and equipment in manufacturing industries. They are also highly scalable, meaning you can use them in a wide variety of control applications.
CompactLogix 5380 Standard Controllers
These controllers can monitor and control remote and local Compact 5069 I/O modules over the EtherNet/IP network, as well as other field devices connected to the network. They support up to 31 local I/O modules, specifically 5069 Compact I/O modules. They also include two (2) configurable EtherNet/IP ports that support Dual-IP addresses, with the option to use Device Level Ring (DLR) or Linear topologies.
They support Integrated Motion over the EtherNet/IP network with up to 32 axes. However, only CompactLogix 5380 standard controllers with an M or P in their Catalog Number are capable of supporting Integrated Motion on EtherNet/IP networks. Check if the selected controller supports this feature if needed.
The available controllers within the category of CompactLogix 5380 Standard Controllers include the 5069-L320ER, 5069-L340ERM, 5069-L306ER, 5069-L306ERM, 5069-L310ER, 5069-L310ER-NSE, 5069-L310ERM, 5069-L320ERM, 5069-L330ER, 5069-L330ERM, 5069-L340ER, 5069-L350ERM, 5069-L380ERM, and the 5069-L3100ERM.
These controllers also provide enhanced security features including logging, controller-based change detection, and role-based access control for Add-On instructions and routines. Since their control functions are optimized for maximum system performance, Standard CompactLogix 5380 Controllers are well-suited for small to large control applications requiring low I/O point counts and minimal axis motion.
Compact GuardLogix 5380 Safety Controllers
Compact GuardLogix 5380 controllers are available within the Logix 5000-series controllers. They function the same way as CompactLogix 5380 standard controllers, but they also provide integrated safety functionalities with drives and motion. The Compact GuardLogix 5380 controller system can communicate with safety I/O devices such as Guard I/O modules, integrated safety drives, and components, via CIP Safety features over the EtherNet/IP network. They support a single controller-network-programming software platform for standard and safety control.
Compact GuardLogix SIL 2 Controllers with a 1oo1 architecture can achieve up to SIL 2/PLd (Category 3) with the use of Safety 5069 I/O modules and safety tasks settings, whereas Compact GuardLogix SIL 3 Controllers having a 1oo2 design architecture can attain up to SIL 3/PLe (Category 4) while using Safety 5069 I/O modules and safety task settings. Note that both Compact GuardLogix 5380 SIL 3 and SIL 2 are Programmable Automation Controllers (PACs) with integrated safety features.
You can interface a Compact GuardLogix 5380 controller to standard 5069 I/O modules via standard tasks. You can also interface it with safety 5069 I/O modules via the safety task. Please note that for safety tasks, the Compact GuardLogix 5380 controllers can only be programmed in Ladder Logic (Ladder Diagram), whereas for standards tasks, these controllers support Ladder Diagram (LD), Structured Text (ST or STX), Function Block Diagram (FBD) and Sequential Function Chart (SFC).
Compact GuardLogix 5380 controllers are widely used either in standalone control systems or in much more complex systems with Compact 5000 I/O modules and other field devices connected via the EtherNet/IP network. Note that when Compact GuardLogix 5380 controllers are used for safety applications, a safety signature has to be used. The safety signature includes a safety signature ID (identification number), as well as a timestamp which should include the time and date.
Here are the available Compact GuardLogix 5380 controllers, from which you can choose the controller that will meet your safety application requirements.

CompactLogix 5380 Process Controllers
These controllers incorporate the functionality of standard CompactLogix 5380 controllers with motion capabilities. They are conformally coated to provide an additional layer of protection when exposed to extreme or corrosive environments.
The Process Controllers are ideal for industrial control applications in Oil & Gas, Metals & Mining, Plastics, Chemicals, Food & Beverage, Chemical, and Life Sciences industries. You can choose either of the following CompactLogix 5380 Process controllers: the 5069-L320ERP and/or the 5069-L340ERP.
How to Power CompactLogix 5380 Controllers
After selecting the correct type of CompactLogix 5380 controller, the next question on your mind would probably be how you will provide power to your controller system. Well, a CompactLogix 5380 system is operated by either Module Power (MOD) or Sensor/Actuator (SA) Power.
MOD Power is the system-side power that powers the controller system and allows the connected modules to transfer data and execute logic. It is provided to the controller through the MOD-Power RTB (Removable Terminal Block), while the field-side power, also known as SA Power, is used to power some of the Compact 5000 I/O modules and other field-side devices connected to the CompactLogix 5380 controller. It is provided to the Logix system through SA Power-RTB (Removable Terminal Block).
It is important to note that both the SA and MOD power should be provided to the controller as DC (Direct Current) power. Also, if you’re using Compact GuardLogix 5380 Safety Controllers, the DC power must be provided from a SELV/PELV-rated power source. A CompactLogix 5380 controller system can only use one MOD power bus. However, the same system can have multiple SA power buses. The first SA power bus starts at the controller and passes across the Compact 5069 I/O modules, which are installed on the right side of the controller. Whenever you’re establishing a new SA power bus, you should use a Field Potential Distributor (5069-FPD). The new SA power bus is then isolated from the previous SA power bus to its left in the CompactLogix 5380 system.
CompactLogix 5480 Controllers
These are real-time Programmable Automation Controllers (PACs) that deliver scalable control, as they support data gathering, analytics, and predictive computations. They are used in monitoring and controlling local/remote Compact 5069 I/O modules and other field devices connected over EtherNet/IP networks. These controllers may only be mounted on a DIN rail.
If you select a controller in this category, it should include three 1GB EtherNet/IP ports, in which two of the ports are configurable and support Dual IP address mode or Linear/ Device Level Ring (DLR). The EtherNet ports enable high-speed I/O communications, as well as Integrated motion control. Hence, you can use the CompactLogix 5480 controllers for mid-size to large scale applications that require faster data throughput and high-performance control.
Depending on your Logix control applications, you can select any of the following CompactLogix 5480 controllers:
5069-L430ERMW CompactLogix 5480 Controller

Compact 5069 I/O Modules
The architecture of Compact 5000 I/O provides a variety of input and output modules for use in a variety of applications from process control to high-speed counters. These modules use Producer/Consumer technology, which supports the sharing of input information and output status among several 5069 CompactLogix Controllers within the 5069 Logix platform. You can use Compact 5069 I/O modules as either local or remote I/O modules in Standard CompactLogix 5380 and Safety Compact GuardLogix 5380 controller systems. The I/O modules are installed on the right side of the Compact 5000 controller. Check the type of controller specified for use with your selected Compact 5069 I/O modules.
Please note that to connect these modules to field-side wiring, you will need a Removable Terminal Block (RTB). Although the RTB has to be ordered separately as it is not supplied with the I/O modules.
The number of local Compact 5069 I/O modules that you can install in a 5069 Logix system varies depending on the type of CompactLogix 5380 controller you have selected. Some standard controllers can allow you to install up to 32 local I/O modules.
The Compact 5069 I/O modules are classified into 3 categories from which you can choose, depending on your application requirements. They include:
Compact 5000 I/O EtherNet/IP Communication Modules
The modules within this category support up to 31 I/O points. They support distributed I/O modules for CompactLogix 5380 and Compact GuardLogix 5380 via the EtherNet/IP network. They also support 1 GB (Gigabyte) embedded Ethernet port switch technology for Device Level Ring (DLR) and Linear topologies.
See that the selected EtherNet/IP communication module has high-speed backplane communication for faster data transmission rates. It should also have a separate power supply for better isolation and powering the connected field devices. Moreover, the selected module should provide improved status indicators to enhance monitoring and troubleshooting of the system.
The available modules within this category include the 5069-AENTR EtherNet/IP Communication Adapter and the 5069-AEN2TR EtherNet/IP Communication Adapter. If small space is a constraint in your application, you can use the slim 5069-AENTR adapter.
Compact 5000 I/O Standard Modules
These modules can be used as Local I/O in a CompactLogix 5380 and Compact GuardLogix 5380, or a CompactLogix 5480 controller system. They can also function as distributed I/O modules to CompactLogix 5380 and Compact GuardLogix 5380 controllers over the EtherNet/IP network, which can be accessed via Ethernet adapters (5069-AEN2TR or 5069-AENTR).
The Standard Compact 5000 I/O modules are available in Digital input or output, High-speed counter (5069-HSC2xOB4), Analog input or output, isolated and non-isolated Relay outputs, AC input/output, DC input/output, Address Reserve Module (5069-ARM), Field Potential Distributor (5069-FPD).
Compact 5000 I/O Safety Modules
These modules support local safety connectivity with Compact GuardLogix 5380 safety controllers. They also provide distributed I/O to the Compact GuardLogix 5380 safety controllers over the Ethernet/IP network, which are accessible via Ethernet adapters (5069-AEN2TR or 5069-AENTR).
Ensure that the safety Compact 5000 I/O module you select can support up to 31 I/O modules per adapter or controller. Also, the selected module should be able to provide faster safety reaction time and enhanced diagnostics information, with a safety rating of up to SIL3/PLe (Category 4).
The available modules within this category include:
- 5069-IB8S
- 24 volts DC CompactLogix 5000 Safety Input Module supporting up to 8 channels
- 5069-IB8SK
- 24 volts DC CompactLogix 5000 Safety Input Module supporting up to 8 channels
- 5069-OBV8S
- 24 volts DC CompactLogix 5000 Safety Configurable Output Module that supports up to 8 channels
- 5069-OBV8SK
- 24 volts DC CompactLogix 5000 Safety Configurable Output Module that supports up to 8 channels
- 5069-SERIAL
- CompactLogix 5000 Serial Interface Module
Powering Compact 5000 I/O Modules
Compact 5000 I/O modules are powered using different types of power. Ensure that the selected CompactLogix 5000 I/O module accepts any of the following power options:
Module (MOD) Power
This is the system side power that is used to operate local or remote I/O systems. Check that the selected Compact 5069 I/O module is drawing the specified amount of MOD power current from the MOD power bus while passing the remaining current to the next module. For example, some 5069 CompactLogix systems require that the total continuous current drawn across the MOD power bus should not exceed 10A (Amperes), maximum, at 18 to 32 volts DC. Also, note the maximum level of MOD power current that should be passed to the next module.
Sensor/Actuator (SA) Power
Some Compact 5000 I/O modules in the CompactLogix 5380 system use the SA (Field-side) power to provide power to field-side devices connected to them. Please note that some Compact 5000 I/O modules only pass the current to the next module along the SA power bus without drawing any of it, while there are other Compact 5000 I/O modules that draw some current from the SA power bus and pass the remainder to the next module.
Local Actuator (LA) Power
This is also Field-side power which is used by some CompactLogix 5000 I/O modules instead of SA power. Note that a module that is specified to use LA power cannot use SA power. You should install the CompactLogix 5000 I/O modules using LA Power on an SA Power bus having the same module type. For example, you can only install a digital I/O module (i.e., a 5069-OB8 module) on an SA Power bus which includes DC type I/O modules.
Other key points to note are:
First off, if you’re using an AC voltage source for the Local Compact 5069 I/O modules, then you must connect the modules to the power source through a Field Potential Distributor (5069-FPD). This is because it is not possible to terminate an AC voltage on the 5069 CompactLogix Controller side.
Second, you should use a MOD external power supply and an SA external power supply. This practice helps prevent operation interruptions which can result if only one power supply is used. For example, if you’re using separate SA and MOD external power supplies and the SA power is lost, the MOD power will still be available to the CompactLogix 5000 I/O modules and the CompactLogix 5380 controller. As such, data transfer and logic execution will continue in the Logix system.
Lastly, the SA external power supply used should be adequately sized for the total current draw from each SA power bus within the Logix system. Likewise, the MOD external power supply used should be adequately sized for the total MOD power bus current being drawn by the CompactLogix 5069 system. When calculating the total MOD-power bus current draw and the total SA-power bus current draw in the Logix system, make sure you consider the inrush current requirements.
Conclusion
Some of the key features you should consider when designing a CompactLogix 5069 system include compatible 5069 CompactLogix Controllers, the required CompactLogix 5000 I/O modules, as well as their accessories, among other things. In summary, if your application for the 5069 CompactLogix system requires safety logic or safety connections, then you should use a Compact GuardLogix 5380 Safety controller with the appropriate safety or standard Compact 5069 I/O modules.
On the other hand, if your Logix system is intended for standard tasks, then you should select the appropriate Standard CompactLogix 5380, CompactLogix 5480, or Compact GuardLogix 5380 controllers, with the compatible standard Compact 5000 I/O modules. Other factors that you should always take into account are the power options for both the CompactLogix controllers and Compact I/O modules used in the system, as well as the mounting specifications.
