3.5.6 Parameterization
The arrangement of the parameter data is performed by your system configuration software PS501 Control
Builder Plus V2.2.1 (or newer) / ABB Automation Builder 1.0 (or newer). ABB GSDML file for PROFINET
devices can be used to configure AI581-S parameters in 3
rd
party PROFINET F-Host systems.
The parameter setting directly influences the functionality of modules and reachable SIL (IEC 61508 ed. 2
and IEC 62061) and PL (ISO 13849).

3.5.7 Circuit examples
Examples of electrical connections and reachable SIL (CL) (IEC 61508 ed. 2 and IEC 62061), Category (EN
954) and PL (ISO 13849) with AI581-S module are presented below.
NOTICE!
Whenever DC = High is used in the circuit examples for safety analog inputs, the following measure
from ISO 13849-1 [10] is used in AI581-S module: Cross monitoring of input signals and intermediate
results within the logic (L), and temporal and logical software monitor of the program flow and detec-
tion of static faults and short circuits (for multiple I/O).
Whenever DC = Medium is used in the circuit examples for safety analog inputs, any of the measures
for input devices with DC
³
90 % can be used from ISO 13849-1 [10].
