Data Center Cooling Monitoring

Problem

Chillers, pumps, cooling towers and CRAH units are controlled by different contractors, so the operator cannot see the whole cooling chain or measure how much energy cooling uses.

Opis rozwiązania

MILESGO gateways collect data from chillers, chilled water pumps, cooling towers, CRAC / CRAH precision air conditioners, BTU / heat meters, electricity meters over BACnet/IP / Modbus TCP / Modbus RTU / M-Bus, and deliver it to the DCIM, SCADA, the energy management system as OPC UA / SNMP / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

chillers
chilled water pumps
cooling towers
CRAC / CRAH precision air conditioners
BTU / heat meters
electricity meters

Protocol path

BACnet/IP / Modbus TCP / Modbus RTU / M-Bus → OPC UA / SNMP / MQTT

Implementation checklist for the project manager

Collect register maps and protocol documents from every equipment vendor early; a missing map is the most common delay.
Commission in read-only mode first; enable write / control points only after the client approves each one.
Record CT ratios, meter IDs and multipliers in the point table; wrong multipliers are the usual cause of billing errors.
Configure NTP so trends, alarms and meter readings carry consistent timestamps.
Agree KPI definitions (for example OEE components or kWh per unit) with operations before building dashboards.
Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.

Project deliverables

Signed point table and protocol mapping
Gateway configuration files and backups
IP address plan and network drawing
FAT and SAT test records
As-built documentation and operator training

Architektura systemu

Field layer: chillers, chilled water pumps, cooling towers, CRAC / CRAH precision air conditioners, BTU / heat meters, electricity meters, connected over BACnet/IP / Modbus TCP / Modbus RTU / M-Bus. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the DCIM, SCADA, the energy management system, which receives the data as OPC UA / SNMP / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

Etapy wdrożenia

1
Site survey and point list
Inventory devices, protocols, register maps, panel space, power and network paths.
2
Design and point table sign-off
Map every point to the target protocol and system; agree it with the client and the upper-system contractor.
3
Configuration and FAT
Build the gateway configuration off site, simulate it and test against the signed point table.
4
Installation and wiring
Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.
5
SAT and alarm tests
Verify values against local readings, test every alarm and command end to end.
6
Handover and support
Hand over configuration backups, point table and as-built documents; train operators.

Korzyści dla klienta

One view of all subsystems instead of separate vendor consoles
Consumption visible by area, system and time period
Reliable trend data for optimisation and fault diagnosis
Monitoring added without changing existing control programs
