Danfoss VLT HVAC Drive FC 102 Option Modules
Option parameters of the VLT HVAC Drive FC 102, as an addition to the drive template.
The Danfoss VLT HVAC Drive FC 102 takes options for fieldbus, extra analog and digital I/O, a bypass and temperature sensors, and has pressure sensor functions for filter monitoring in air handling units. This Modbus RTU template holds those option parameters, so you can read their status and change their settings from ModbusCloud next to the drive template.

Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show the pressure across up to four filters of an air handling unit and the current specific fan power on a dashboard.
- Send an email when the bypass status word changes, so you know the drive was bypassed.
- Track filter running hours and the extra energy cost of a dirty filter to plan the replacement.
- Keep a history of the extra temperature inputs of the sensor input option.
Installation
Add the Danfoss VLT HVAC Drive FC 102 template as described there; this template uses the same RS485 connection, address and settings.
In ModbusCloud, add a second Modbus RTU device with the same address on the Gateway and import this template.
Delete the registers of options that are not fitted in your drive.
Check that the values of your options look plausible.
Things to watch for
Most registers return an error or 0.
The option card parameters only exist when the matching card is fitted in the drive, and the pressure sensor functions only give values when sensors are configured. Keep the registers you use and delete the rest from the device in ModbusCloud.
How do I find the register of a Danfoss parameter?
The register number is the parameter number times ten, so parameter 31-26 is register 31260 and address 31259 in the template. The parameter number is in the comment of each register.
Some array parameters always show the first value.
For array parameters the drive returns the element chosen in Array Index Pointer. Write the index you want there first, then read the array parameter.
