Description
The 1747-L553 is an SLC 5/05 processor that belongs to the SLC 500 Programmable Logic Controller (PLC) platform. This controller has the highest memory among the SLC 5/05 category which is 64 KB memory.
It has integrated RS32 Sub-D 9-Pin connector for establishing peer-to-peer communication with locally installed Human Machine Interface (HMI) or a programming workstation.
It also has an integrated Ethernet that is ideally used for communication over a long distance, minimum of 100 meters at 10/100 mbps transmission speed. It is also ideal for establishing connection to multiple devices at a time.
These Two (2) port may also be used simultaneously without affecting the processor’s logic execution capability.
This controller is ideal for medium to large scale application, with control requirements ranging from manual to automatic control of Discrete or analog loops as well as implementing complex control techniques with the,
utilization of a wide number of embedded instructions. It may be used in Factory automation, Process Automation even in motion and position control requirements.
It is also capable of sending Messages to other Allen-Bradley PLC platforms such as PLC 5, CompactLogix and ControlLogix via a specified communication protocol. Though integrated with Ethernet and RS232 ports,
this processor may be installed with communication adapters such as Remote I/O (RIO), Data Highway Plus (DH+), DeviceNet and DH485.
It may be installed to any SLC 500 chassis. This processor module has a fixed slot assignment of slot Zero (0).
It contains a PLC-5 processor-based advanced instruction set. The 1747-L553 can stand alone or be distributed throughout the system for SCADA applications. The 1747-L553 processor has a total user memory of 64K,
words with 60K words for data/program and 4K words for just data. It has up to 4096 inputs, 4096 outputs, and 480 local analog I/O. It has a program scan time per keyword of 0.9ms and 0.225 milliseconds I/O scan time.
The 1747-L553 has a backplane current of 1 Amp at 5 Volts DC and 0 Amps at 24 Volts DC. It has a maximum of 3 local I/O chassis with maximum 30 module I/O slots in local I/O chassis.
For communication, it uses Ethernet and RS-232 ports that can be configured for connection to the 1761-NET-AIC converter. It has standard battery-backed RAM and Flash backup memory. With this processor,
Remote I/O Scanner module and DeviceNet Scanner module can be additionally installed to configure I/O via Universal Remote link or DeviceNet network. The 1747-L553 processor provides shorter bit-instruction ,
execution time of 0.37 milliseconds and 10/100 Mbps Ethernet port. Its DH+ communication port is 3 times faster than the DH-485 port. It has all the features of other SLC 5/03 processors like online programming,
flash memory upgrades, floating-point math, and a built-in real-time clock, key-switch, and calendar. The 1747-L553 is intended for use in clean and dry industrial environments with a 0 to 60 degrees Celsius operating,
temperature and a 30G operating shock.
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.
