Logical I/O of a Safety Device

The FSoE parameters of a Safety Device are located on the Safe Configuration tab of the logical I/O of a Safety Device.

The variables that are used for the safety application to access the I/Os are defined on the I/O Mapping tab of the editor.

For a detailed description of the editor and the tab, see Logical I/O in the help of CODESYS Safety Extension.

FSoE communication parameters

The FSoE parameters comprise the general FSoE communication parameters for the configuration of safe communication, as well as in some cases also additional device-specific FSoE application parameters, which are described in the documentation of the device.

Caution

For EtherCAT devices with several parallel FSoE connections, each one must have its own FSoE address specified. These different FSoE addresses of the same EtherCAT device must not be confused.

  • FSoE address

    • Address of the Safety Device (FSoE Slave)

      (Position of the DIP switch),

    • The Value field is editable.

Caution

The FSoE address must be unique within the EtherCAT fieldbus (even for several safety controllers in the same fieldbus).

  • Connection ID

    • Connection ID for the Safety Device

    • The Value field is editable.

Caution

The Connection ID for the Safety Device must be unique within the EtherCAT fieldbus (even for several safety controllers in the same fieldbus).

For topology T2 when several safety controllers are used below the same EtherCAT master: The uniqueness of the FSoE connection IDs must be guaranteed in the entire EtherCAT network of the EtherCAT master.

  • WatchdogTime

    • The Value field is editable.

The parameters listed here are the FSoE communication parameters. These can still be followed by device-specific parameters (FSoE application parameters).

Tip

The variant of FSoE application parameters, which are transferred to the device via FoE services (not via the safety controller), is not supported.
