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.
