Interference-free Bus Terminals

Use of interference-free Bus or EtherCAT Terminals in safety applications
If a Bus or EtherCAT Terminal is described as interference-free, this means that the consecutive
terminal behaves passively in a safety application (e.g. in the case of the all-pole switch-off of a po-
tential group).
In this case the terminals do not represent an active part of the safety controller and do not affect
the Safety Integrity Level (SIL) or Performance Level (PL) attained in the safety application.
For details, please refer to chapter 2.17f in the TwinSAFE application manual.
Pay attention to the hardware version
Please pay attention to the information about the hardware version and non-reactivity of the respective Bus
Terminal in the chapters "Technical Data" or "Firmware Compatibility"!
Only terminals with the appropriate hardware version may be used without the attained SIL/PL being af-
fected!
The Bus or EtherCAT Terminals regarded as interference-free at the time of preparing this document are
listed in the following tables together with their respective hardware versions.
