PFD/PFH Calculation in Accordance with EN 61508 and VDI/VDE 2180

The values that appear in the input fields at the start of the program are examples to demonstrate the operation and function of the program. Please replace these values with the actual values of the respective safety function.

The spreadsheet for calculating the PFD/PFH according to EN 61508 and VDI/VDE 2180 has been carefully prepared. Nevertheless, we expressly state that the calculated PFD/PFH values only apply in compliance with the above-noted rules and boundary conditions. No liability is assumed for the calculated results, and no claims are made about their correctness; the calculation of the PFD/PFH of the respective safety function is the sole responsibility of the user.
