Appendix: example of a bidirectional safety coupling
18. Appendix: example of a bidirectional safety coupling
The following example describes a biderectional safety coupling between 2 AS-i
circuits.
Couple slave A
Couple slave B
AS-i circuit 1, OSSD 1
AS-i circuit 1, OSSD 2
AS-i circuit 2, OSSD 1
AS-i circuit 1:
OSSD 1: All EMERGENCY STOPs in circuit 1.
OSSD 2: Alle other safety objects + couple slave B.
AS-i circuit 2:
OSSD 1: All EMERGENCY STOPs in circuit 2 + couple slave A
