PROFIsafe Driver
PROFINET is a communication protocol for transmitting data between controllers and devices fast and safe via ethernet. As an application profile of PROFINET, PROFIsafe is responsible for the communication between safety devices (F-Device) and safety controllers (F-Host). It has no influence on the network topology since it is a separate layer on top of PROFINET and allows a failsafe communication on the basis of standard network components (no additional wiring is necessary). This means that safety-relevant and standard data can be transferred via the same line.
The WinCC OA PROFIsafe-over-PROFINET driver (in short PROFIsafe driver) is used to connect a WinCC OA host to a PROFINET network and allows the communication with F-Devices and F-Hosts. If the driver is operated as PROFINET-only driver, all PROFIsafe specific configuration steps can be omitted.
For the use of the WinCC OA PROFIsafe driver in a WinCC OA Safety project, the basic and operating conditions of the WinCC OA version used, must be followed according to the "WinCC OA basic and operating conditions" document. A version of the document matching the WinCC OA version used in the project is available in the download section of the ETM portal.
Configuration
F-Device configuration
The WinCC OA host on which the driver is running must be configured as F-Device and must be connected to a PROFINET network with at least one safety controller (F-Host). A WinCC OA host which is configured as F-Device can be connected to the F-Host and the exchange of data and status information is possible. Refer to TIA Portal hardware configuration for further information on configuring a F-Device.
WinCC OA configuration
According to the configuration in the TIA Portal, corresponding transfer areas must be defined for the PROFIsafe driver.
Notes and Restrictions
The PROFIsafe Driver is currently not available for Red Hat Enterprise Linux 9
