Integration Checklist

• Confirm existing site inventory, I/O counts, and any required standards (tagging, alarms, naming).
• Request current drawings, network diagrams, and as-built documentation (or plan for discovery).
• Define acceptance testing: FAT/SAT steps, cutover plan, and rollback expectations.
• Confirm PLC platform, programming environment, licensing, and source code handoff requirements.
• Clarify communications path, latency constraints, polling rates, and any coverage/path study requirements.
• Define remote access method, auditing/log retention, and IT/OT segmentation boundaries.
