Hands-on Trend IQ411 commissioning on a DIN-rail rig: power-up, addressing, point-to-point I/O checks and strategy in Trend SET, re-implementing duty/standby, interlocks and a PID loop, then comparing with the ESP32 and PLC versions, and viewing it from Niagara and BACnet clients.

Learning Niagara 4 the integrator's way: a station bringing in this portfolio's own devices over BACnet/IP, Trend and Modbus TCP drivers (S7 optional), with tagging, histories, alarms, schedules and Px graphics, then compared with the Home Assistant + Node-RED supervisory layer. Route: the Niagara 4 TCP.
