Identify the existing control estate
Record controller and HMI versions, ownership, backups, communications and permitted access. Do not assume an open protocol or editable program.
Make machine states and ownership explicit without assuming that different controllers already speak the same language.
Existing OEM control boundaries, accessible signals and the agreed supervisory scope.
Record controller and HMI versions, ownership, backups, communications and permitted access. Do not assume an open protocol or editable program.
Describe the meaning, origin, validity and acknowledgement of ready, running, unavailable and cleaning states. Separate process coordination from safety-rated functions.
Agree who validates loss of communications, bad instrumentation, power interruptions and restart. Functional requirements need project-specific engineering before code or commissioning.
