FAQ

What is the function of the AS-i F-Link capability of this module?

The AS-i F-Link feature allows the SIRIUS 3RK3 Modular Safety System to connect AS-Interface safety monitors as slaves to the PROFIBUS DP network, enabling integrated diagnostics and control of AS-i safety devices.

Is this module compatible with modern TIA Portal software?

No, the SIRIUS 3RK3 MSS family is programmed using its own specific software, MSS ES, and is not integrated into the TIA Portal. For TIA Portal compatibility, a migration to a modern system like SIRIUS 3SK2 or SIMATIC Safety Integrated is required.

What does a flashing ‘BF’ (Bus Fault) LED indicate on this module?

A flashing red ‘BF’ LED indicates a problem with the PROFIBUS DP communication. Common causes include a broken or disconnected bus cable, incorrect bus termination, a wrong station address, or a configuration mismatch with the PROFIBUS DP master.
