3.1.1 Purpose

SM560-S is the Safety CPU for up to SIL3 (IEC 61508 ed. 2 and IEC 62061) and PL e (ISO 13849) safety
applications. The Safety CPU is mounted on the left side of the Non-safety CPU, e.g., PM573, PM583,
PM592 or others with the firmware version from V2.2.1, on the same Terminal Base. The communication
between the Non-safety CPU and the Safety CPU takes place through the internal communication bus,
which is integrated in the Terminal Base. The data interchange is realized by a dual-port RAM.
Depending on the used Terminal Base, 1 ... 4 Communication Modules (e.g., CM579–PNIO, etc.) can be
simultaneously employed at one Non-safety CPU. However, only one SM560-S Safety CPU can be operated
simultaneously at one Non-safety CPU.
The Safety CPU is programmed and configured via the dual-port RAM using safety system configurator and
CoDeSys Safety programming environment, which are a part of the PS501 Control Builder Plus V2.2.1 (or
newer) / ABB Automation Builder 1.0 (or newer) software.
The configuration of SM560-S is saved non-volatile in a Flash EPROM.

3.1.2 Functionality

3.1.2.1 Overview
SM560-S Safety CPU for AC500 PLCs is available from version V2.2.1 (or newer) of the PS501 Control
Builder Plus software / version 1.0 (or newer) of the ABB Automation Builder software and can be used with
Non-safety CPUs (PM573, PM583, PM592 or others with the firmware version from V2.2.1 and with suitable
TB5xx units). Power supply is provided via the coupler interface of the Terminal Base.
