| The attribute "User Address" is a sequence of up to 18 letters and numbers | |||
| assigned to each datapoint (physical and pseudo). | |||
Example | The temperature of a room is recorded at a sensor input; the associated user | |||
| address could be as follows: | |||
| Room Temp.1.10 | (Room temperature, 1st floor, room 10) | ||
| The datapoint can be accessed directly by selecting this user address on the XI581 | |||
| (not with XCL5010, Excel 100C), XI582, and | |||
|

| In the case of basic types of physical data, a user address always corresponds | |||
| exactly to one technical address (see Table 15). | |||
| The user address of flexible datapoints may refer to up to six technical addresses. | |||

Value
When the controller is working in automatic (the attribute "Operating Mode" is set to "Auto"), the value currently being processed by the program, or the current status, can be found in the attribute "Value". The attribute "Value" for an analog input could contain, for example, the current room temperature of 21 °C / 70 °F.
A pump switched by a digital output could contain the current status of the pump, for example ON, in its attribute "Value".
