FAQ

Q1: What is the Allen‑Bradley 1747‑L553?

A1: The Allen‑Bradley 1747‑L553 is a SLC 5/05 programmable logic controller (PLC) processor module for the SLC 500 system, featuring Ethernet/IP, RS‑232, and RS‑485 communication ports.

Q2: What communication protocols does the 1747‑L553 support?

A2: It supports Ethernet/IP, DH+, RS‑232 (DF1 full‑duplex/half‑duplex), and Modbus RTU (via RS‑485) for industrial networking and device integration.

Q3: What is the maximum I/O capacity of the 1747‑L553?

A3: The 1747‑L553 supports up to 4096 digital I/O points and 256 analog I/O points in a local chassis, with expansion via remote I/O racks.

Q4: What software is used to program the 1747‑L553?

A4: It is programmed using RSLogix 500 (or Studio 500 Logix Emulate for legacy support), which provides ladder logic, function block, and structured text programming.

Q5: Is the 1747‑L553 still supported by Rockwell Automation?

A5: While the 1747‑L553 is a legacy product, Rockwell Automation continues to offer limited support (repair, spare parts, and documentation); new projects are recommended to migrate to ControlLogix or CompactLogix platforms.
