Descriptors

Informative descriptors A controller contains up to 128 physical datapoints and up to 256 pseudo datapoints. The Excel 100C provides 36 physical datapoints. An individual user address can be assigned to each of these 384 datapoints. 255 plain-language descriptors can be created with a maximum of 32 characters each. These descriptors are then assigned to datapoints in the datapoint description via the attribute "Descriptor". Descriptors complete the information concealed behind the user address. They can contain, for instance, a reference to a section of a building. The following list is an example of the relationship between user addresses and descriptors:

User Address Room temp floor 1 Room temp floor 3 Room temp floor 10 Room temp corridor Flow temp floor 1 Lights floor 1 Lights corridor

Descriptor

Heating circuit, West wing Heating circuit, West wing Heating circuit, East Heating circuit, East Heating circuit, West wing Building section V Building section V

Engineering Unit

The attribute "Engineering Unit" contains a list for selecting different engineering units for both analog datapoints (physical and pseudo), totalizer inputs (physical and pseudo), and digital datapoints.

If, for instance, the external temperature is measured by an analog datapoint, the engineering unit of this datapoint must be set to "°C" or "°F". If the electrical load is detected by a totalizer input, the engineering unit must be set to "kWh" for kilowatt- hours.

Feedback Delay

The attribute "Feedback Delay" determines the time delay between, e.g. when a pump switched on (and detected) and when this status is made available to a program.

High/Low Alarm/Warning Limits

Specifying limit values In the case of analog inputs (e.g. inputs for sensing room temperature) and pseudo analog points (for instance, internally computed datapoints for the heating flow setpoint), two minimum and two maximum monitored limit values may be entered.
