All the units used within a safety function must be considered when calculating the safety
characteristic data.
INFORMATION
A safety function's SIL/PL values are not identical to the SIL/PL values of
the units that are used and may be different. We recommend that you use
the PAScal software tool to calculate the safety function's SIL/PL values.
The safety­related characteristic data (PFH, PFD) are mean values. They have been calcu­
lated at an average ambient component temperature of 40 °C and apply for the ambient
temperature range stated in the technical details.
