Components of the F-Device

Standard controller

Safety controller

Development system

Device tree (F-Device)

  • Selection of the predefined F-Modules which the PROFINET Device should support

Safety configuration (F-Module)

  • Definition of the F-Addresses of the individual F-Modules in the configurator of the corresponding logical device of the safety application

Safety POU editor

  • Implementation of the functional behavior of the individual F-Modules in IEC 61131-3 editors of the safety application

IEC application

DrvProfisafeFDevice.library (F-Parameter, PROFIsafe diagnosis)

SafetyProfisafeDevice.library (safety layer)

Safety application

(specific device application)

Runtime system

Device-specific driver for PROFINET Device, for example IoDrvProfinetDevice.library (fieldbus access layer)

Device-specific driver

Acyclic communication with the safety controller, for example DrvSafetyIoService.library

F-Module F-Parameter and diagnosis

(acyclic data)

F-Module PROFIsafe telegram (Safety PDO)

F-Module I/O mapping

(failsafe I/O data)

Ethernet

Device-specific interface, safety controller / PROFINET Device controller

The functional behavior is programmed in the SIL3 application. For detailed information, see the Safety User Manual, in the "Implementation of F-Modules" chapter.
