Description
The 1756-L81EXT Controller is a controller manufactured by Allen-Bradley as a member of the ControlLogix-XT controllers product series. These controllers are designed to work the same as the conventional ControlLogix controllers do.
Products in the ControlLogix-XT product line comprises control components as well as communication system components which are coated conformally to add a protective layer when ,
the controllers are exposed to corrosive and harsh environments. The Allen-Bradley 1756-L81EXT ControlLogix-XT Controller can tolerate and work in a temperature range from -20 to 70 degrees Celsius when it is used with the ,
Flex I/O-XT series products. It can withstand a temperature range from -25 to 70 degrees Celsius when it is used on its own. The operators who have used the LXT chassis are advised to upgrade to the K version of the chassis.
Some of the main specifications and features of the 1756-L81EXT Controller include the ability to handle 32 controller tasks, 1000 programs per task, and unlimited local I/O event triggers. Like many ControlLogix controllers,
the 1756-L81EXT Controller also features integral communication ports which are 1 USB port and an embedded Ethernet port. It also supports multiple communication options like the Ethernet/IP, Remote Input/Output,
Data Highway Plus, DeviceNet, ControlNet, SynchLink, and the third-party process and device networks. The device also has support for multiple programming languages like the relay ladder logic, structured text,
function block diagram, and sequential function chart programming languages. It operates on 3 MB of user memory and it has a thermal dissipation rating of 21.2 BTU per hour.
The controller has a current draw rating of 5 milliamps at 1.2 Volts DC and 1.2 Amps at 5.1 Volts DC.
The latest development of Allen-Bradley (Rockwell Automation brand) in 2025, based on its recent technology trends and industry dynamics, can speculate on the following possible directions:
1. Industrial automation and digital transformation deepening
AI and machine Learning integration: Allen-Bradley controllers, such as the ControlLogix family, are expected to further integrate AI algorithms for predictive maintenance, anomaly detection, and adaptive control.
Digital Twin technology: With the FactoryTalk software suite, digital twin capabilities can be enhanced to help companies optimize production line design and simulate production processes in real time in a virtual environment.
2. Edge Computing and Industrial Internet of Things (IIoT)
Edge intelligence: CompactLogix or Micro800 series controllers may support more powerful edge computing capabilities, reducing reliance on the cloud and improving real-time data processing efficiency.
TSN (Time Sensitive Networking) applications: Industrial networking equipment such as Stratix switches may support the TSN protocol, ensuring low latency transmission of mission-critical data.
3. Sustainable manufacturing solutions
Energy saving technologies: New frequency converters (such as the PowerFlex series) and motor control solutions are introduced to improve energy efficiency and support companies in achieving carbon neutrality.
Circular economy support: Develop products with modular designs that are easy to upgrade or recycle and reduce e-waste.
4. Enhance network security
Zero-trust architecture: Embed stricter authentication and encryption in industrial control systems to protect against advanced persistent threats (APTs).
OT/IT Converged Security: Deepen cooperation with partners such as Cisco to provide end-to-end industrial cyber security solutions.
5. Collaborative Robots (Cobots) and flexible production
Human-machine collaboration optimization: Allen-Bradley may introduce more corobot-friendly safety controllers to simplify production line deployment and support small-batch, personalized production needs.
6. Open ecosystems and partnerships
Integration with IT/ cloud service providers: Further deepen the cooperation with Microsoft Azure, PTC and other companies to promote the seamless connection of industrial data cloud analysis and enterprise applications.
Open source tool support: Potentially open more apis or support for open source programming languages (such as Python) to attract the developer ecosystem.
7. Augmented Reality (AR) and remote operations
AR Assisted Maintenance: Provide more intuitive device diagnostics and remote expert support through the FactoryTalk AR platform, combined with devices like Hololens.
