Property Description

function to edit the unit strings of data point fields.

This read-only property is assigned to the data point

automatically, and is based on the point’s

<UCPTformatDescription>. It defines the base type of the data

point, as defined in the base_type_t enumeration in the

BAS_Controller resource files for the SmartServer.

This property specifies the maximum number of fields that the

data point may have. For scalar and enumerated data point this

property is 0 if the unit string cannot be edited, or it is 1 if the

unit string is editable.

For structured data points, this property is 2 or more based on

the SNVT or UNVT used by the data point. For example, the

default value in <UCPTmaxFields> for a SNVT_switch data

point will be 2 (value and state), and it will be 3 for a

SNVT_setting data point (function, setting, and rotation).

This property applies to output data points. It defines the

maximum amount of time that may elapse before the data point

is updated on the network, if it is set to a non-zero value.

For example, if a SNVT_temp value data point is changing by

one degree every 10 seconds and this property is set to two

seconds, the SmartServer will update the value of the data point

on the network every two seconds, even though the value of the

data point is not changing more than once every 10 seconds.

The receiver can use this output as a heartbeat. The receiver

will know something is wrong if he or she does not receive an

update every two seconds.

This property applies to output data points, and defines the

minimum amount of time that may elapse between data point

updates if it set to a non-zero value.

For example, if a SNVT_temp value data point is changing by

one degree every half second and this value is set to two

seconds, the data point will only be updated every two seconds

with the latest value, even though the value changes more

frequently than that.

This property is used to control the maximum time that can

elapse after an update to a bound network input before another

update can occur. If this period elapses without an update, the

<UCPTpointStatus> of the data point will be updated to

AL_OFFLINE. You could create an Alarm Notifier to trigger

an alarm notification when this happens. For more information

on Alarm Notifiers, see Chapter 7,

Alarm Notifier.

The valid range for this property is any value between 0.0 sec

and 6,553.4 seconds. Setting <SCPTmaxRcvTime> to the

default value of 0.0 disables the receive failure mechanism.

Optional. This value is initially taken from the resource files, if

1 2 ... 45 46 47 48 49 50 51 52 53 54 55 ... 442 443
