SM560-S / SM560-S-FD-1 / SM560-S-FD-4 are safety CPUs for up to SIL 3 (IEC 61508), max. SIL 3 (IEC 62061) and PL e (ISO 13849-1) safety applications. The safety CPU is mounted on the left side of the non-safety CPU 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.
Depending on the used terminal base and used non-safety CPU, more than one communication module can be simultaneously employed at one non-safety CPU. However, only one safety CPU can be operated simultaneously at one non-safety CPU.
The safety CPU is programmed and configured via the DPRAM using safety system configurator and AC500-S Programming Tool which are a part of the Automation Builder software.
The configuration of the safety CPU is saved non-volatile in its flash EPROMs.
Information on how to combine safety CPUs with its non-safety environment can be found in the compatibility information.
