Safety CPU Unit


The Safety CPU Unit controls up to 32 Safety I/O Units.

EN ISO13849-1 (PLe/Safety Category4), IEC 61508 (SIL3) certified.

One connection using Safety over EtherCAT (FSoE) * protocol enables flexible configuration by mixing the Safety Units with standard NX I/O.

The Safety CPU Unit controls up to 128 Safety I/O Units.

Hardware and safety circuits can be configured using the Sysmac Studio (Ver. 1.07)

Compliant with IEC61131-3

Safety programs can be standardized and reused efficiently by using POUs for design and operation.

* Safety over EtherCAT (FsoE): The open protocol Safety over EtherCAT (abbreviated with FSoE "FailSafe over
    EtherCAT") defines a safety related communication layer for EtherCAT. Safety over EtherCAT meets the requirements
    of IEC 61508 SIL 3 and enables the transfer of safe and standard information on the same communication system
    without limitations with regard to transfer speed and cycle time.
