 Poll on Startup: For input data points this property defines, whether the data point
shall be polled once at start-up. Poll-on-startup can be enabled independently of the
poll cycle. See Section 5.1.2.
 Pollcycle: For input data points, this property defines the poll cycle in seconds. Set this
property to 0 to disable polling. See Section 5.1.2.
 Receive Timeout: For input data points, this property defines the receive timeout in
seconds. Set this property to 0 to disable polling. See Section 5.1.2.
 Min Send: For output data points, this property defines the min send time in seconds.
See Section 5.1.2.
 Max Send: For output data points, this property defines the max send time in seconds.
See Section 5.1.2.
 Send-on-delta: For output data points this property defines, if value updates shall be
sent only once they meet the COV condition of the data point. For analog data points
the analog COV increment is used. If not checked, updates are always transmitted
according to min and max send times. See Section 5.1.7.
 Use Linear Scaling: If this property is enabled, the analog values are pre-scaled from
the technology to the data point. This scaling is in addition to any technology-specific
scaling factors. If enabled, the properties Custom Scaling Factor and Custom Scaling
Offset accept the scaling factors. See Section 5.1.7.
 Custom Scaling Factor, Custom Scaling Offset: These properties only exist, if linear
scaling is enabled. They apply to analog data points only. See Section 5.1.7.
 Only notify on COV: This property assists for binary and multi-state input data points.
It defines, if a data point shall trigger an update only when the value changes or on
every write. If this is enabled, consecutive writes with the same value do not trigger an
update. If you want to convey every write, disable COV on the data point.
 Persistent: This property defines, if the last written value shall be stored as a persistent
value. Persistent data points restore that value after a restart from the persistent storage.
See Section 5.1.4.
 Default Value: This property defines a default value (see Section 5.1.3). Enter a
default value to enable this feature in the data point. Delete the value entirely to remove
the default value. If no default value is defined, this property reads ―N/A‖. The default
is no default value.
 Point Type: This is the base data point type, e.g., ―Analog Datapoint‖.
 Direction: This is the data point direction. Use input or output as directions.
 Unit Text: For analog data points this property contains a human-readable text for the
engineering units of the scalar value, e.g., ―kilogram‖.
 Analog Datapoint Max Value: For analog data points this property contains the upper
limit of the supported value range. Note that this does not define an alarm limit.
 Analog Datapoint Min Value: For analog data points this property contains the lower
limit of the supported value range. Note that this does not define an alarm limit.
 Analog Datapoint Precision: For analog data points this property defines the number
of decimals. ‗0‘ specifies an integer value. Display units may use this to format the
floating point value accordingly.
 Analog Datapoint Resolution: For analog data points this property defines the
smallest possible value increment.
 Analog Point COV Increment: This property is valid for analog input data points. It
specifies by which amount the value needs to change, before an update is generated. If
every write shall generate an update even when the value does not change, specify 0 as
