Allen-Bradley 1747-L553 SLC 5/05 Ethernet Processor with 64K Memory

Product Description

The 1747-L553 represents the high-capacity tier of the Allen-Bradley SLC 5/05 processor family. Engineered for complex automation tasks, this controller integrates a powerful logic engine with native Ethernet communication capabilities. It allows for high-speed data exchange across local area networks (LANs) without the need for additional interface modules, making it an ideal choice for modernizing legacy SLC 500 systems.

With a substantial 64K word memory capacity, the 1747-L553 (Series A/B/C) provides ample space for extensive user programs, sophisticated floating-point math, and large data tables. It supports a wide array of discrete and analog I/O modules across multiple chassis, offering the scalability required for plant-wide control architectures in demanding industrial environments.

Primary Application Scenarios

The 1747-L553 is frequently utilized in large-scale manufacturing applications, such as automotive assembly, food and beverage processing, and water treatment facilities. Its Ethernet port facilitates seamless connectivity to HMI/SCADA systems and remote programming, while the 64K memory accommodates the complex logic needed for coordinated motion or extensive PID loop control.

Professional FAQ

• Can I upgrade my SLC 5/01 or 5/02 to a 1747-L553?

  Yes, the 1747-L553 is backward compatible with existing SLC 500 I/O modules and chassis. However, you must ensure the power supply in your chassis can handle the 1000 mA backplane draw of the 5/05 processor.

• How do I reset the IP address if it is unknown?

  The IP address can be reset or configured via the RS-232 port using RSLinx Classic or by using the BOOTP/DHCP utility provided by Rockwell Automation over the Ethernet connection.
