Product Overview

The 1747-L552 is an advanced single-slot controller module engineered by Rockwell Automation under the Allen-Bradley SLC 500 series. Operating as an SLC 5/05 Processor, this unit directly interfaces with system backplanes to bridge machine-level control with enterprise networks. Featuring native Ethernet capability, the 1747-L552 provides out-of-the-box vertical integration, enabling seamless IIoT connectivity and real-time data exchange without requiring specialized gateway hardware.

According to Global PLC Spare HUB's Insight, engineering teams prefer this processor for medium to large manufacturing cells due to its deterministic scan performance and robust dual-port communication architecture. Field experience shows that leveraging the onboard Ethernet port drastically reduces integration time compared to legacy DH-485 networks.

Technical Specifications

Installation Guide

Frequently Asked Questions

Q: What happens if the lithium battery fails during system operation?

A: The onboard capacitor maintains RAM data for 30 minutes, allowing safe battery replacement without program loss if executed promptly.

Q: Can multiple MSG instructions share the same Ethernet connection node?

A: Yes, outgoing messaging instructions share a single connection per destination node, up to the maximum limit of 48 total concurrent connections.

Q: How do I select the right memory backup module for this processor?

A: Selection depends on program size; the 1747-M13 flash backup module is fully compatible and recommended for non-volatile storage requirements.

Q: What is the recommended practice when replacing an older processor with the 1747-L552?

A: Always back up the existing program file via RSLogix 500, verify chassis power supply loading limits, and record communication parameters before swapping modules.
