Id #

The Id field shows the internal number of the channel under which it is stored internally. When creating a new element, the field is empty. The number is for display purposes only and is automatically defined by the system.

Interface #

Here you can see which interface the channel belongs to and which type the interface has. This information is for viewing purposes only.

Name #

The name of the channel. The name is displayed in selection lists and may also be visible to the user (e.g. if the channel is displayed in a chart or a notification originates from the channel or refers to it).

Comment #

The comment field is for free use by the integrator/system administrator. It is used exclusively to document the configuration. Information can be entered here, e.g. the purpose of the channel, comments on the connected hardware, room/floor and other special features. The content of this field is irrelevant for X2.

Option: Persistent #

If you set this checkbox, X2 saves the current value of the channel persistently (after a restart, the channel then has the last set value again. If the checkbox is off, the channel has no value after a restart until it is either written to or a value is read from the interface.

Option: Chart #

Check this box to record the value of the channel. Channels whose value is recorded can be displayed in charts as graphs. This is suitable for measured values (temperature, humidity, etc.). The average value is calculated over a period of 5 minutes and saved every 5 minutes. The system automatically recognizes when the channel is used for a chart and records data even if you do not set the checkbox. You must set the checkbox yourself if you want the data to be recorded in charts regardless of the use of the channel.

Writing/Reading #

Defines the access mode for the channel, read, write or both. Depending on the interface, this field may not be changeable.

Unit #

Defines the value unit and thus also the data type of the channel. If the autoconfig checkbox is set, some interfaces can override the unit or lock the setting.

Start value #

This input field defines the start value of the channel. You should make sure that the start value you specify is compatible with the unit of the channel, otherwise you may get undesirable behavior.
