Manual binding/unbinding can be performed in the 'Trailers' panel. A special switch button is located against each trailer —  or  correspondingly. If you do not have enough access rights, then the button is disabled.

Click 'Bind to unit' button (), choose a unit the trailer to be bound to, and click OK.

 Availability of units in this list depends on the work list in the Monitoring panel. If there are no units in the list, click 'Add all available' button . If the list is still empty, then you have no access rights to these units.

To unbind a trailer from a unit, click an icon of a unit opposite to trailer's name, and then use the corresponding button (). Besides, you can unbind a trailer by registering a new working shift, or by deleting bindings from history.

Automatic method of binding trailers to units requires both special equipment (such as iButton system), and special adjustments in the system.

1. Create a special sensor of 'Trailer binding' type in the properties of each unit intended for auto-binding. A parameter for this sensor can be avl_driver or some other depending on your equipment and its configuration.

2. Create a list of units for any resource the trailers of which are intended to be bound automatically. In order to do so, click 'Auto-binding' icon (), and follow the steps listed below.

Upon clicking the 'Automatic binding' icon a list of available resources is opened. Here you choose a resource the trailers of which will be used in automatic binding (with the units chosen in the next dialog). In order to understand which trailers belong to a particular resource, go back to the 'Trailers' panel, and apply a filter by resource (dropdown menu to the right of 'Create' button).

After choosing a resource, click 'Next'. If only one resource is available, then it will be chosen automatically.

The next dialog contains a list of units to which the trailers from a chosen resource can be bound automatically. Depending on the access rights possessed, the list can be viewed or edited.

Thus, a trailer will be automatically bound to a unit with the help of iButton in case that this unit has a special sensor configured in its properties and that this unit is indicated in the list of auto-attachable units applied to the resource where the trailer belongs.

Automatic binding of trailers is removed in the same way: summon 'Automatic binding' dialog, choose a resource, and uncheck flags of units for which the automatic binding will not be used.

This option can be used, for example, if you would like to register working shift post factum. Use the corresponding button () opposite to a driver's name, choose the 'Register working shift' option, and click 'Next'. In the appeared dialog window choose a unit to which the driver will be assigned in the indicated shift, click 'Next'. Now indicate time of shift beginning and end. Moreover, you can indicate either only beginning or only end time. For example, you have indicated shift beginning, and you would like its end to be registered automatically when a unit arrives to garage (as a geofence). To do so, create a notification of 'Geofence' type with method of action 'Reset driver'. Anyway, registering a working shift you can use only past dates or current time (no future allowed).

Incorrect registrations of trailers can affect reports and their informational efficiency. That is why sometimes you may need to delete such (un)bindings from the database. In the interval registering dialog choose the last option — 'Delete bindings' — and press 'Next'. Specify time interval, and press 'Show' to display all bindings and unbindings of the trailer on the interval. Check invalid messages and press OK to delete them.

Note.
