Siemens S7 vs Modbus TCP compared. Native data-block access vs universal register addressing, typed vs flat data, where each wins, and how Siemens sites run both.
Read articlePROFINET vs S7 Communication: What's the Difference
PROFINET IO and S7 communication are not competing protocols — they coexist on every Siemens controller. PN-IO is the deterministic fieldbus for cyclic I/O; S7 is the acyclic read/write protocol over TCP port 102. Ports, RFC 1006, RT/IRT timing, GSDML, and macOS tooling explained.
