Addressing

Previous chapterNext chapter Show allShow all    Hide allHide all

Addressing the variables of the BACnet driver is done with the unique names of the variables. The datapoints of the BACnet driver are uniquely referenced by the object names. The object name of the device object is placed before the object name of the BACnet object; the names are separated by a dot (e.g. BPS10.d10a002); for schedule objects, the name of the property is attached, again separated by a dot. The virtual datapoints of the type BACnet component status represent the status of the connection. They are uniquely identified by the object name of the device object.

String length

Only available for String variables: Maximum number of characters that the variable can take.

Driver object type

Depending on the employed driver, an object type is selected during the creation of the variable, and can be changed here later.

Data type

Data type of the variable, which is selected during the creation of the variable; can be changed here later.
ATTENTION: If you change the data type later, all other properties of the variable must be checked and adjusted, if necessary.
