KUKA Error KSS15002 — FSoE communication (KSP, SIB, smartPAD, PROFIsafe slaves)

Info

KUKA KSS15002 (“FSoE communication (KSP, SIB, smartPAD, PROFIsafe slaves)”): “Safe device communication error <device>”: safety communication (FSoE) with a participant has been interrupted. Likely part: KSP (KUKA Servo Pack — axis servo drive) +2 more.

Updated 2026-09-09 · LogrobotLM reference

Cause

“Safe device communication error <device>”: safety communication (FSoE) with a participant has been interrupted. Classic case after hardware replacement: if several safe modules are exchanged at the same time (or swapped), the FSoE addresses are no longer reassigned automatically.
