Engineering notes
For the AK840M-0808DTN, engineering review covers logic re-implementation, an explicit I/O map, protocol mapping, interlocks, and validation boundaries against the existing application. Any cross-brand proposal is a candidate replacement — subject to engineering review.
- TIA Portal programs do not import into CoDeSys — ladder/FBD/SCL logic is re-implemented and re-tested from scratch
- This record is a fixed 8 DI / 8 DO digital-only footprint — S7-1200 applications using analog inputs or signal-module expansion need verified expansion options at review
- PROFINET-connected peripherals from a Siemens installation need protocol re-architecture — confirm fieldbus scope against the AK840 datasheet at review
