Site.service

This field is only available when adding a new point.

Site and Service are used in conjunction to identify the current value service of the point. A PNT can store points for any current value service. Maximum length is 8 characters. Click … to select a Service.

Facility ID

ID of the point’s facility. Up to 20 characters. No spaces.

Uniform data code

UDC of the point. Up to 10 characters. No spaces.

If the UDC is in the TRS, the UDC is displayed and serves as the default for the point description. If the UDC is not in the TRS, the UDC description shows as <not found>.

Click … to select a UDC. The actual UDC is accompanied by its UDC Description.

Long point ID

The long identifier of the point.

CygNet naming standards for point identifiers are as follows:

Point ID

The identifier of the point.

CygNet naming standards for point identifiers are as follows:

Short description

Description of the point. Free-form text up to 24 characters.

Long description

Description of the point. Free-form text up to 80 characters.

Point scheme

The Point Scheme governs system-wide alarm priorities, alarm categories, alarm colors, point states, etc.

See Point Scheme or Understanding the CvsMetadata File for more information.

Point type

The point data type. Options are:

• Analog Input
• Analog Output
• Digital Input
• Digital Output
• Enumeration Input
• Enumeration Output
• String Input
• String Output

See Point Types for more information.

HyperPoint

Enables the point as a HyperPoint.

Options are 0 (No) or 1 (Yes).

See HyperPoint Scripting for more information.

Activate script

Enables the point’s script if the point is a HyperPoint.

Options are 0 (No) or 1 (Yes).

Manual update mode

Click to enable manual update mode (aka manual mode) for the point record. When enabled the associated Current Value Service is blocked from updating the point.

Options are 0 (No) or 1 (Yes), the default value is 0 (No).

• See the PNT security event MANLEDIT for information about limiting the editing of this setting.

• See Edit Point Value for information about enabling manual update mode for a point value in the Current Value Service.

• See OPCIS Data Points for information about using the manual update mode setting with OPCIS data points.

• See Configuring a Status Point for a SetPoint Button for information about toggling manual update mode when initializing the value of the status point associated with the SetPoint button.

Primary units

Specifies the primary units of measure. A drop-down menu is provided for selection.

See PNT Engineering Units.

CygNet Software supports aliases for some unit names, which can be typed manually in the Primary Units fields on the General page in the PNT Editor. Examples include: plural or singular forms of common units, e.g., barrels for barrel, calorie for calories, and feet for foot; or other abbreviations, e.g., A for amp, CBM for cubic meter, forward slash (/) for per, and yrs for years. Accepted unit aliases will be converted to standard engineering units when specified in a point's configuration record or associated data group.

Alternate units

Specifies alternative units of measure. A drop-down menu is provided for selection.

Example

Alternative units could be C for Celsius instead of F for Fahrenheit, or US gallon instead of barrel for a tank level.

See PNT Engineering Units.

Allowed updates

Specifies the allowable point update type.

For instance, “All Updates,” which is the default, indicates that both a user or the system can update the point record.

Options are:

• All Updates - both a user or the system can update the point record. (B)
• Internal and User (C)
• External Only - only another service can update the point's value. For example, an HSS can update a UIS point. (E)
• Internal Only - only the point's CVS can update the point's value. (I)
• No allowed updates - no point value updates are allowed. (N)
• Internal and External (T)
• User Only (U)
• External and User Only (X)

ACS application

Specifies the name of the security application that governs security for the point.

Click … to select an application.

Initial value type

The Initial value type property specifies the type for the point's initial value.

• None — The point starts up with a blank (null) value. No initial value. (N)
• Restore — If the point's CVS is configured to persist values (PERSIST_VALUES keyword is enabled), then the service will use the value from the CVS.Persist.dat. If the service is not configured to persist values, the point will start with the value specified in the Initial value property in the point configuration record. (R)
• Service Configuration — If the point's CVS is configured to persist values (PERSIST_VALUES keyword is enabled), then the service will persist the point's last known value when the service starts. If the service is not configured to persist values, the point will start with a blank value. (D)
• Specified Value — The point starts up with the value specified in the Initial value property in the point configuration record. (I)

System name

Value from CMSYS table.

Initial value

Options are:

• Rational number (AI/AO)
• 0 or 1 (DI/DO)
• Free-form text (SI/SO)
• Entry from conversion table (EI/EO)

Display attribute

Value from the PNTDISP table.

Point status

Enables the point as Active (or inactive). Can only be edited after the point has been created.

Last updated user ID

The user ID of the last user to edit the point.

Created time

The timestamp when the point was created.

Last updated time

The timestamp when the point was last updated.
