Compatibility and Project Checks
- ✓Match the existing S7-1500T project, firmware and technology objects to the replacement hardware.
- ✓Use a compatible SIMATIC Memory Card containing the validated project backup.
- ✓For successor migration, review performance, memory and motion behavior rather than assuming drop-in equivalence.
