| Q4 | Is SEC401 interchangeable with EC401? | No. Their names are similar, but their system roles and supported control architectures differ. |
| Q5 | What should be checked during commissioning? | Verify both bus paths, node addresses, cable length, connector seating, module status and diagnostic indications. |
| Q6 | What should accompany an inquiry? | Send the full model, style, quantity, controller type, installed slot and clear nameplate photographs. |
