In addition to the use of bus-independent, conventional safety terminals (such
as IB IL SAFE 1-PAC) in an Inline station, safety terminals can also be used in a bus system
with a safe protocol (INTERBUS Safety, PROFIsafe). In this type of bus system, the safe
data is transmitted between the safe controller and the safety modules via the bus using a
safe protocol. This means that the same cable is used for both safety-related
communication and standard communication.
INTERBUS Safety can be used to achieve safety functions with the following requirements:
–
–
–
INTERBUS Safety thus meets the highest safety requirements for the process and
manufacturing industry.
Within the Inline product range, the following safety terminals are available for
INTERBUS Safety, for example:
IB IL 24 SDIO 4/4/1, IB IL 24 SDI 8-PAC, IB IL 24 SDO 8-PAC, IB IL 24 SDOR 4-PAC

Safety terminals for PROFIsafe are in preparation.
PROFIsafe is a profile for PROFIBUS and PROFINET certified according to IEC 61508.
PROFIsafe can be used to achieve safety functions with the following requirements:
–
–
PROFIsafe thus meets the highest safety requirements for the process and manufacturing
industry.
