Overview
1.9 Fail-safe operation of KP8F and KP32F
KP8, KP8F, KP32F
20 Operating Instructions, 11/2011, A5E03284305-02
Released protocols
The HMI device uses the following protocols for communication with the controller:
● PROFINET IO for standard communication
● PROFIsafe Mode V2.0 for fail-safe communication of the KP8F and KP32F
1.9 Fail-safe operation of KP8F and KP32F
Configuring software
For fail-safe operation of the HMI device, the following software is required:
● STEP 7 V5.5 and higher
● SIMATIC S7 Distributed Safety, as of V5.4
Fail-safe automation system
A fail-safe automation system (F System) is used in plants with increased safety
requirements.
An F system controls production processes so that residual error probability is taken into
consideration to achieve a safe operating state when a shutdown occurs. An immediate
shutdown therefore does not pose a danger to people or the environment.
