Defined signals. Defined boundaries.
A service-first conceptual architecture for supervisory elevator intelligence.
This is a functional overview, not a field wiring drawing. Every installation requires qualified engineering review of interface ratings, approvals, fault effects and the particular elevator controller.
From field evidence to technician decisions.
The supervision channel is shown left to right. A separate boundary keeps advisory AI away from motion/safety actuation.

Communication configuration to be verifiedExplains codes and recorded evidence. Cannot command motion, override interlocks, or declare equipment safe.
Elevator primary control and safety functions remain separately engineered. Any UCM protective output requires independently validated, approved architecture—not the advisory branch illustrated here.
The diagram intentionally omits terminal numbers, voltage conversion circuits and safety-loop connections. Do not connect 110/220 VAC or 230 VDC field signals directly to a low-voltage PLC or HMI. Protective interfaces must be correctly rated and independently assessed for the actual installation.
Decisions that belong in the engineered package.
Field signal schedule
Source, voltage type, transient levels, isolation boundary, monitored meaning and permissible loading.
Communications & power
RS-485 topology and isolation, Ethernet segregation, surge/grounding strategy and DC supply verification.
Commissioning evidence
Approved I/O map, test procedure, expected states, fail-safe review, recorded results and sign-off authority.
