First release of node-red-contrib-s7-rust: Node-RED nodes for Siemens S7 PLCs, with the protocol clients written in Rust and running inside the Node-RED process. It is the next generation of @oriolrius/node-red-contrib-s7.

Highlights

  • Two protocols: classic S7comm (S7-200/300/400/1200/1500, LOGO! 8) and S7CommPlus (S7-1200/1500) with symbolic access to optimized DBs, TLS and password login.
  • Five nodes: s7 endpoint, s7 read, s7 write, s7 watch (with a conditional rate) and s7 info (CPU state, SZL, clock, blocks, browse, alarms).
  • Fast and light: no child process and no IPC; reads are grouped into as few requests as the PDU allows; changes are detected on the raw PLC bytes.
  • Linux x64 only, prebuilt for glibc ≥ 2.28 and musl (Alpine, the Node-RED Docker image).
  • Licence LGPL-3.0-only. The README has the exact map of the S7 functions that are covered.

Upgrade notes

New package: install node-red-contrib-s7-rust from the palette. It does not replace @oriolrius/node-red-contrib-s7 in existing flows.
