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.
8.2 Classification according to ZVEI, CB24I
The following tables describe the classes and specific values of the product interface and
the classes of interfaces compatible with it. The classification is described in the ZVEI posi-
tion paper "Classification of Binary 24 V Interfaces - Functional Safety aspects covered by
dynamic testing".
