The PROFIsafe F-Host library, responsible for managing safety communication, is unable to verify the safety source addresses of connected devices. This typically indicates an outdated or incompatible F-Host library version, which compromises the system's ability to validate the authenticity and integrity of safety messages. Consequently, safety communication cannot be reliably established.
Click steps to track your progress.
Verify that the F_Source_Add parameter configured in the safety PLC's project for each F-Device matches the actual F_Source_Add assigned to the physical device.
Check for duplicate F_Source_Add values across all PROFIsafe devices connected to the F-Host, ensuring each device has a unique address.
Ensure the F-Host library and F-Device firmware versions are compatible by referencing the manufacturer's compatibility matrix.
Perform an online comparison between the safety PLC's project configuration and the actual configuration on the F-Devices to identify discrepancies.
Re-download the entire safety PLC project, including the F-Host library and F-Device configurations, to ensure consistency.
If the issue persists, consider updating the F-Host library in the engineering software to the latest compatible version.
