ABB SM560-S Safety Processor Module

The ABB SM560-S, also cataloged as the SM560-S Safety Processor Module, operates as a dedicated hardware component for localized safety-related logic execution and critical loop protection up to SIL 3 (IEC 61508 / IEC 62061) and PL e (ISO 13849-1) within AC500-S safety PLC network platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and Driver Integration

The safety processor installs directly onto a standard AC500 terminal base adjacent to the primary non-safety CPU, executing specialized dual-channel safety loops concurrently. This segregated internal hardware architecture processes emergency stop, light curtain, and safety mat arrays without adding processing latency to the standard control layer. Safe control data is transmitted across the local chassis backplane or routed over distributed topologies utilizing PROFIsafe layer profiles deployed on top of Profinet deterministic networks. Full firmware flash compatibility via ABB Automation Builder allows engineers to perform secure system updates, managing high-density safety I/O scaling setups while maintaining continuous connection tracking across isolated sub-networks.

Frequently Asked Questions

Q: Can the SM560-S safety processor operate as a standalone controller without a standard CPU?

A: No. The SM560-S is designed to function as a companion safety module that works alongside a standard AC500 non-safety CPU (such as a PM573, PM583, or higher). The standard CPU handles regular program execution, while the SM560-S exclusively manages safety-instrumented routines.

Q: What programming languages are supported for creating the safety logic on this module?

A: Safety routines for the SM560-S are configured within the Automation Builder environment using Safety PLCopen certified languages, specifically Structured Text (ST), Function Block Diagram (FBD), and Ladder Diagram (LD) tailored for safety-critical environments.
