Before lunch, you dive into an existing CODESYS Structured Text codebase, tracing control logic to decide what stays on the PLC and what must transition to the product controller. In the afternoon, you stand up robust PLC-to-controller communications, scale signals correctly, and commission a station so it is production-ready.
