Managing device types

To process data from various device types, Cumulocity IoT uses device protocols which are stored in a database.

Click Device protocols in the Device types menu in the navigator.

In the Device protocols page you will find a list with all device protocols available in your account.

The device protocol list shows the following information:

• the device protocol type (for example Modbus, CANOpen, LoRa)
• the device type name
• the number of resources for the device (at the right)
