Generator & ATS Monitoring

Il problema

Generator controllers and transfer switches are checked on weekly walk-rounds, so a failed start, a switch stuck on one source or low fuel is found too late.

Panoramica della soluzione

MILESGO gateways collect data from generator controllers, automatic transfer switches (ATS), level sensors, run/stop and fault dry contacts over Modbus RTU / Modbus TCP, and deliver it to the DCIM, the BMS, SMS, email and messaging alarms as SNMP / BACnet/IP / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

generator controllers
automatic transfer switches (ATS)
level sensors
run/stop and fault dry contacts

Protocol path

Modbus RTU / Modbus TCP → SNMP / BACnet/IP / 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.
For hard-wired signals, list each DI/DO/AI/AO with its type (dry contact, 4–20 mA, 0–10 V, PT1000) and choose I/O modules accordingly.
Commission in read-only mode first; enable write / control points only after the client approves each one.
Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
Confirm DIN-rail space and a stable 12–24 V supply in each panel; use UPS-backed power for critical monitoring.
Check 4G signal and the SIM data plan at every site before committing to cellular backhaul.

Architettura del sistema

Field layer: generator controllers, automatic transfer switches (ATS), level sensors, run/stop and fault dry contacts, connected over Modbus RTU / Modbus TCP. 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, the BMS, SMS, email and messaging alarms, which receives the data as SNMP / BACnet/IP / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

Fasi di realizzazione

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.

Valore per il cliente

Alarms reach the right person by SMS, email or messaging apps
Abnormal conditions seen early, before they become failures
Timestamped records for compliance and reporting
Monitoring added without changing existing control programs
