Building Engineering Monitoring with the S7000 System

This S7000 installation monitors engineering equipment at Ukrtelecom’s head-office building in a distributed system designed by Business Comfort using S7000 modules from Neuro System. Four control panels contain S7000 distributed-control modules connected over RS-485, with intermediate relays for switching power equipment.

Controllers and operator station

The main panel uses an S7386-50 PC-compatible controller based on an i386 processor. It is programmed in UltraLogik 32, which supports IEC 61131 programming languages. Panels serving floors 2–4 use S7050 digital input/output modules, power supplies and power relays. A PC in the electrical staff room runs the SCADA interface for monitoring and control.

NewLogic SCADA, supplied by ESTA, collects data from the main panel over Modbus, archives it for later analysis, records alarms and notifies staff, displays information graphically, and produces summaries and reports from archived data.

Functions monitored

• Lift-lobby lighting on floors 2–4, operated locally, remotely from the electrical staff room, or automatically on a schedule;
• Lift direction, alarm status, floor indication and the number of the lift in alarm;
• Fire-alarm status on each floor;
• Building heat use, including heat-carrier temperature and flow, current and cumulative consumption, and monthly reports.

Electricians and the building dispatcher view system diagrams that bring lift status and fire information together. The S7000 platform’s distributed design also supports phased system expansion.
