Legacy-series compatibility

Do not substitute a different CPU 224 generation only by matching the front-panel I/O count. Verify power supply, output technology, program memory, firmware and Micro/WIN project compatibility.

COMMISSIONING HANDOVER
What to capture before replacement
Archive the STEP 7-Micro/WIN project, system block, communication settings, retentive data requirements, expansion-module order and field wiring before replacement.

•Exact MLFB and suffix
•Supply and output load type
•Micro/WIN project backup
•Communication parameters
•Expansion-module order
•Destination and required date
FAQ
CPU 224 replacement questions
Is this an S7-1200 CPU?

No. It is a SIMATIC S7-200 CPU 224 and uses the S7-200 engineering and expansion environment.

Are the outputs relays?

No. This DC/DC/DC variant uses ten DC transistor outputs.

Can another CPU 224 replace it directly?

Only after checking the full MLFB, supply, output type, memory generation, firmware, communication settings and project backup.
