Coselium · Building automation
Controllers, remote I/O and software for building automation.
Coselium controllers run the application inside the device with Sedona, and connect to the supervisory system over BACnet, Modbus and MQTT, and to Niagara N4 with the cosel modules. Hardware, firmware and programming tool are developed by one team.
FiOC-4040-point Sedona controller that runs the application on the device FiOC-40 · Controller
Control logic and 40 I/O points in one DIN-rail unit.
The application runs on the device, so the panel keeps its logic even when the supervisory link drops. It is programmed live with Coselium Workbench or Niagara N4.
FiO-40 · Remote I/O
Adding points without programming.
FiO-40 comes with a ready Modbus and BACnet point list and is defined in an existing BMS without programming. When needed, a licence also lets it work as a Modbus gateway or BACnet router.
Coselium Workbench · Windows, macOS
Editing the application while the device runs.
Components are wired on the wiresheet; changes reach the device over SOX immediately and values are monitored live.
FiOC-32 · Coming soon
Monitoring at the panel door, networks on separate ports.
A 2.8" TFT display and rotary encoder allow values to be monitored and adjusted at the panel; two Ethernet and two RS-485 ports keep field and supervisory networks apart.

Why Coselium
Our own R&D
Hardware, firmware and programming tools are developed by Cosel Elektronik’s own team.
One hardware family, two roles
FiOC-40 is a controller running a Sedona application on the device; FiO-40 is a remote I/O that needs no programming. Both have 40 points.
Workbench or Niagara N4
Applications are programmed with Coselium Workbench or from Niagara N4 with the cosel modules.
Licences when needed
Modbus TCP ↔ RTU gateway and BACnet IP ↔ MS/TP router functions are enabled by licence when required.
Product family
Controllers, remote I/O and the software that programs them. FiOC-40 and FiO-40 are in stock; FiOC-32 is coming soon.

Frequently asked questions
What is the difference between FiO-40 and FiOC-40?
Both come from the same hardware family and have 40 points (16 DI, 8 UI, 8 DO, 8 FIO). FiOC-40 is a controller that runs the control application on the device with Sedona; communication and point structure are set up per project. FiO-40 is a remote I/O that needs no programming and comes with a ready Modbus and BACnet point list.
How does it integrate with Niagara N4?
With the cosel modules: the FiOC-40 is reached through a direct device connection or a station driver. Kit Manager manages kits, Device Manager finds supported devices and Point Manager adds the selected points to the station. Devices can also connect through the standard BACnet/IP or Modbus TCP drivers.
Which software is used for programming?
FiOC-40 is programmed live over SOX with Coselium Workbench (Windows, macOS) or inside Niagara N4 with the cosel modules. FiO-40 needs no programming; it is configured from its local web interface or over BLE.
Which functions need a licence?
On FiO-40, basic Modbus RTU/TCP and BACnet/IP, MS/TP use needs no licence; a Level 1 licence enables the Modbus TCP ↔ RTU gateway and Level 2 adds the BACnet IP ↔ MS/TP router. On FiOC-40 the BACnet router is an optional add-on licence.
When will FiOC-32 be available?
FiOC-32 is in preparation; the release date will be announced once it is confirmed. You are welcome to contact us through the contact form for information.
