Description
Allen-Bradley 1747-L532/D SLC 5/03 Processor Module
The Allen-Bradley 1747-L532/D, also cataloged as the 1747-L532 CPU Processor Module, serves as the primary SLC 5/03 controller utilized to execute cyclic program processing across SLC 500 chassis-based control systems. It provides deterministic scan execution and direct coordination with RS-232 and DH-485 communication layers for ladder logic exchange and remote I/O handling.

Backplane Execution & EtherNet/IP Deterministic Constraints
The 1747-L532/D implements SLC backplane transaction timing with fixed-cycle scan arbitration. Backplane current draw at 5 V DC is limited to 500 mA, constraining total chassis loading under multi-slot I/O expansion. The DH-485 token-passing bus enforces deterministic node arbitration, while RS-232 DF1 port handles point-to-point asynchronous frame exchange. Firmware execution aligns instruction-level scan sequencing with fixed interrupt windows, ensuring predictable I/O refresh timing under 30-slot chassis configurations.
Frequently Asked Questions
Q: Can the 1747-L532/D be hot-swapped in an energized SLC chassis?
A: No. The processor is not designed for live insertion. Removal under power may disrupt backplane synchronization and DH-485 token state.
Q: What is the backplane current limitation impact on expansion modules?
A: Total load must remain within 500 mA at 5 V DC. Exceeding this limit can cause bus undervoltage and I/O scan failure.
Q: Does the processor support firmware upgrade via RS-232 port?
A: Firmware updates are not field-upgradable through RS-232. Memory and firmware behavior are tied to fixed SLC 5/03 architecture.
Field Installation Guidelines
Install the 1747-L532/D only in slot 0 of a compliant SLC 500 chassis. Ensure chassis power is fully isolated before insertion. Verify backplane alignment pins are fully seated before applying mechanical force. RS-232 and DH-485 cabling must follow shielded twisted-pair routing with single-point earth grounding of cable shields. Avoid routing communication lines parallel to high-voltage switching conductors to minimize induced noise on DF1 frames.
