02 / Complete-line interfaces
Design normal production and the conditions that disturb it
PLC code can meet local machine needs yet conflict at line interfaces, hide abnormal states or leave operators without a safe restart path. Connect buyer, supplier, local contractor, utility provider, quality team and operations across drawings, software, site work, materials, tests, training and handover. Record both physical connections and data boundaries, including meter location and responsibility for calibration. Review startup, steady production, short stops, restart, low or high demand, format or recipe change, cleaning and shutdown. The interface must protect both the incoming condition and the requirement of the next module.
