A programmable logic controller (PLC) is the industrial computer that runs deterministic control logic for machines and lines, start, stop, interlocks, and cycle timing. PLC integration is the software work of exchanging signals and data between those controllers and higher-level systems: HMIs, MES, historians, vision PCs, and cloud dashboards.
Good integrations respect safety and timing. Handshake protocols, tag mapping, and clear fault states matter more than pretty charts. Codoop builds the application layer that talks to PLCs, operator UIs, telemetry, vision triggers, and work-order hooks, so automation is observable and owned by your team rather than locked inside a single vendor laptop.
