Sending FiOC-40 data to a remote system with MQTT
To bring field values into a cloud dashboard, an energy monitoring tool or your own application, you can use MQTT. What does MQTT give you on FiOC-40?

Reading the front-panel LEDs
The front-panel LEDs on FiOC-40 and FiO-40 show the state of every channel by colour. This note summarises what the colours mean, so that on site it is clear at a glance what is working and where a fault is.

Connecting fan-coil thermostats to the BMS: FiOC-40 BACnet router
BACnet thermostats talking over RS-485 can reach the BMS on Ethernet without a separate router. This note describes the router feature of FiOC-40.

When 40 points are not enough: expanding FiOC-40 with FiO-40
A large air handling unit or a panel serving several pieces of equipment can exceed 40 points. How to keep control on one device and add points with FiO-40 modules.

Adding points to an existing BMS without programming: FiO-40
You do not need a new controller to add a few sensors or outputs to a building. FiO-40 adds 40 points to the existing BMS without writing a program.

Before you open a support request: where to find serial number, MAC and firmware version
Adding the device’s serial number, MAC address and firmware version to a support request speeds up the fix. This note shows where to find them on the device and in the web interface.

Servicing from the Niagara station: users, clock and backups
Once a FiOC-40 is in a Niagara station, many service tasks are done in one place: users, clock, application backup and device information. This note summarises what is done where.
· Technical note
What do outputs do when power returns or the network drops?
Which state a pump or valve is left in when power comes back or the BMS link drops should be known at design time. A summary of how Coselium devices behave.

Reading energy, water and gas meters
Pulse-output meters can be connected straight to FiOC-40 and FiO-40 without an extra module. How to wire them and what to watch for.
· Technical note
Two ways to connect a FiOC-40 to Niagara N4
For quick programming you can connect directly without a station; for continuous monitoring you bring the device into a Niagara station. This note summarises how the two paths differ and when each one is suitable.
· Technical note
Relay or FIO? Driving loads the right way
The device has two kinds of output: relays and flexible FIO outputs. This note briefly explains which one to use for a pump, valve or damper, and how.
· Technical note
Schedules that live on the controller: how FiOC-40 runs without a BMS
A plant that switches on and off with working hours does not need a permanent BMS connection. On FiOC-40, schedules are part of the application and run on the device itself.
· Technical note
Which sensors can I connect? A practical guide to UI inputs
The eight universal inputs on FiOC-40 and FiO-40 read most field sensors, from temperature probes to pressure transmitters. Which sensor is wired how, and what to watch for?

FiOC-40 in an air handling unit panel: which signal goes where
An air handling unit panel holds temperature sensors, valve and damper actuators, fan start commands and fault contacts. This note summarises how they map onto the FiOC-40 channels.

Terminating an RS-485 line correctly: the BIAS / OFF / EOL switch
Most dropouts on an RS-485 line come from wrong termination. With an example, here is which position the small switch on Coselium devices should be in.

Licences on FiO-40: which level for which job?
Using FiO-40 as remote I/O needs no licence. A licence only comes in when you want the device to link two different networks. This note briefly summarises which level is needed in which case.
