Features:
- Nine-slot UR2 rack: the frame carries the S7-400 communication and peripheral buses
- Flexible station role: the rack can serve documented central or distributed arrangements
- Dual supply positions: two locations support an approved redundant power configuration
Architecture focus: Select CPU or interface hardware for the intended station role.
Configuration focus: Keep the physical module order aligned with the STEP 7 project.
Fault focus: Treat simultaneous module alarms as a possible rack-level symptom.
