Professional FAQ
- Q: Can I use the UR2-H rack in a mixed S7-400H and S7-400F setup?
A: Yes, as long as all installed modules are compatible with redundant operation and safety configuration. - Q: How can I check if both rack segments communicate correctly?
A: Monitor system diagnostics in Step 7 or TIA Portal; communication status appears under rack diagnostics. - Q: What is the best way to maintain heat dissipation?
A: Keep at least 30 mm clearance above and below the rack, and avoid covering vent areas. - Q: Does the rack support hot swapping of CPU modules?
A: Hot swapping is possible in redundant systems when properly configured with backup synchronization. - Q: How do I prevent noise in long distributed installations?
A: Use shielded backplane connectors and route grounding cables separately from power lines.
