Frequently asked questions
What is FacilityOS?
FacilityOS is a unified operations platform for critical facilities. It brings FMCS, BMS, EPMS, EMS, SCADA, PLC/DCS, CMMS, DCIM and CEMS into one product, with a control-room video wall and a read-only AI assistant.
Which industries does it support?
11 industries with 48 segments: semiconductors, displays, new energy, biopharma, data centers, manufacturing, metals, glass, logistics, commercial buildings and healthcare.
Can FacilityOS control fire alarm or gas detection systems?
No. Life-safety equipment — fire alarm, gas detection, emergency power transfer — and electrical protection relays are monitored only. FacilityOS verifies that the expected linkage happened and notifies people, but never sends these systems commands.
Which protocols are supported?
BACnet/IP and BACnet/SC, Modbus TCP and RTU, OPC UA, KNX, SNMP v1/v2c/v3, MQTT, DL/T 645, IEC 60870-5-104, IEC 61850, M-Bus, EtherNet/IP, DNP3, Siemens S7 and ONVIF.
What happens if the network goes down?
Control continues in the field PLCs and DDCs. The gateway stores every reading on disk and sends the backlog in order when the connection returns, so history has no holes; any period that could not be kept is shown as a gap.
Do we have to replace our existing BMS?
No. During the pilot your existing BMS and EPMS stay in place as the primary systems. FacilityOS starts read-only and opens control step by step.
How are changes to equipment made safe?
Every write goes through 8 steps — request, validate, approve, pre-check, execute, read back, verify, complete. The requester cannot approve their own change, and success is decided by the read-back.
Does the AI assistant operate equipment?
No. It only gives advice through read-only queries, and every suggestion is accepted or rejected by a person. It is off by default.
Is there a demo?
Yes. The live demo at demo.facilitysystem.com needs no sign-in and has 11 sample sites with simulated live data, reset every night.
What if my equipment brand is not listed?
Any device that speaks a supported protocol can be connected: it starts from the generic protocol template and is adjusted to the vendor's point list.
