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.
