Frequently Asked Questions about 1747-L553
Question: What are the memory specifications of the 1747-L553 processor?
Date Update:03/06/2025
Answer:

The 1747-L553 is equipped with 64,000 words of user memory, which is divided into 60K words for program and data and 4K words for data only. It uses CMOS RAM with battery backup and supports external memory via the 1747-M13 memory module. This large memory capacity allows the controller to execute complex logic and data processing.

Question: How do I upload to Allen-Bradley SLC 5/05 1747-L553?
Date Update:03/06/2025
Answer:

To upload a program from the 1747-L553, connect your PC to the processor using either the Ethernet port (RJ-45) or RS-232 serial port. Then, launch RSLogix 500, select “Who Active” in the communication settings (via RSLinx), and browse for the processor. Once connected, use the “Upload” function in RSLogix 500 to retrieve the logic and data. Be sure to save the uploaded project as a .RSS file for future use or editing.

Question: What is the purpose of the 1747-L553 processor module?
Date Update:03/06/2025
Answer:

The 1747-L553 is a high-performance processor module from the SLC 5/05 series designed to control complex industrial automation systems. It supports up to 64K words of user memory and offers both Ethernet and RS-232 communication capabilities. This makes it suitable for mid- to large-scale applications requiring flexible connectivity and high memory capacity. It supports both discrete and analog control, and allows integration with SCADA and HMI platforms.

Question: How is the 1747-L553 different from SLC 5/03 or 5/04 processors?
Date Update:03/06/2025
Answer:

The key difference is the inclusion of a native Ethernet port in the 1747-L553, which supports faster and more modern networking compared to the DH-485 in 5/03 or DH+ in 5/04. Additionally, it offers 64K of memory, which is greater than most SLC 5/03 and 5/04 models, making it better suited for more demanding applications.

Question: Is the 1747-L553 still in production?
Date Update:03/06/2025
Answer:

No, the 1747-L553 has been discontinued by Rockwell Automation. Although it is no longer in active production, it is still supported in many legacy systems and available as surplus or refurbished equipment. For new designs, Allen-Bradley recommends migration to CompactLogix or ControlLogix platforms.
