| Step | Required Check |
|---|---|
| 01 | Match the complete article number and hardware status with the project documentation. |
| 02 | Confirm 24 V DC supply capacity, grounding, mounting space and heat-dissipation requirements. |
| 03 | Install the required SIMATIC Memory Card and verify the TIA Portal and firmware combination. |
| 04 | Review PROFINET device names, addresses, IRT topology and connected automation components before startup. |
Check the complete suffix, hardware status, firmware version, TIA Portal release, SIMATIC Memory Card, 24 V DC supply, PROFINET IRT topology, mounting dimensions and connected modules. Compare the original CPU label and project backup before replacing an installed controller. Similar CPU 1511 variants may have different technology, safety or interface functions.
