We are getting multiple OT projects and need more hands to support us in terms of this. I’m consolidating several Industry-grade PCs that run bespoke Python applications into our existing Operational Technology environment. The immediate goal is to create a clean, well-documented integration pathway that lets these machines exchange data safely with the rest of the plant network while respecting every cyber-security control already in place. Here’s what I’ll hand over on day one: current network maps, the Python sources, and a short list of approved protocols (mainly Modbus/RTU). From you I need a streamlined integration plan, the actual Python interface code or refactor, and clear documentation that anyone on the OT team can follow without hunting for tribal knowledge. Security-first thinking is vital; every connection must be authenticated, encrypted where practical, and logged for audit. Deliverables • Production-ready Python modules or wrappers that link the Industry PCs to the wider OT layer • Step-by-step configuration and hardening guide (PDF + markdown) covering firewalls, user privileges, and patching cadence • Annotated network diagram showing all new data paths and trust boundaries • Final verification script or checklist so we can reproduce your test results in our staging rack We already have the entire application, but it's not productionalized, nor living up to the standards we need. WE need proper documentation, clean and efficient code everything you would imagine on a 24/7 industrial running resilient system.
