FiO-40
40-point Modbus / BACnet remote I/O, no programming required
A 40-point remote I/O module that connects to a supervisory system without programming, using a fixed Modbus register map and BACnet object model. Depending on the licence level it also acts as a Modbus gateway or BACnet router.
- BACnet/IP
- BACnet MS/TP
- Modbus TCP
- Modbus RTU
- BLE
Overview
FiO-40 is built for adding field points to an existing BMS or controller. Channel structure and addresses are fixed: the integrator takes the register and object list from the reference appendix and maps it straight into the supervisory system.
Protocols
One field protocol runs at a time: Modbus RTU/TCP slave or BACnet/IP / BACnet MS/TP. On Modbus, function codes FC01, FC03, FC05, FC06, FC15 and FC16 are supported; analogue values are fixed-point and UI values can also be read as float32.
Licence levels
- Base: Modbus RTU/TCP and BACnet/IP, BACnet MS/TP
- Level 1: Modbus TCP ↔ RTU gateway
- Level 2: Modbus gateway and BACnet/IP ↔ MS/TP router
Fail-safe behaviour
When communication is lost, outputs fall back to default values defined per channel. Settings are made from the local web interface or from a mobile device over Bluetooth LE; software updates are installed over the air.
Highlights
- 40 physical points: 16 DI (DI1–DI4 counters), 8 UI, 8 relay DO, 8 FIO
- Modbus RTU/TCP slave or BACnet/IP / BACnet MS/TP
- Level 1 licence: Modbus TCP ↔ RTU gateway
- Level 2 licence: Modbus gateway + BACnet/IP ↔ MS/TP router
- Fixed register map and BACnet object model
- Per-channel output defaults on communication loss
Typical applications
- I/O expansion in AHU, pump, boiler and chiller panels
- Adding dry contacts, analogue sensors and universal points to an existing BMS
- Driving damper and valve actuators, relays and contactors
- Fast retrofit integration through a fixed Modbus/BACnet map
