TagBrowseOpen Fields

ADDR

The register address.

254

The address of the register in the I/O device that the variable is associated with.

The format and prefix of the address will depend on the protocol the I/O device uses.

ARR_SIZE

Array size

11

An integer representing the size of the array configured for a variable tag.

1 means it is not an array.

CLUSTER

Cluster name.

16

The cluster the tag exists on.

COMMENT

Comment.

254

A user-configured comment.

CUSTOM1

Custom field #1.

64

A user-defined string.

CUSTOM2

Custom field #2.

64

A user-defined string.

CUSTOM3

Custom field #3.

64

A user-defined string.

CUSTOM4

Custom field #4.

64

A user-defined string.

CUSTOM5

Custom field #5.

64

A user-defined string.

CUSTOM6

Custom field #6.

64

A user-defined string.

CUSTOM7

Custom field #7.

64

A user-defined string.

CUSTOM8

Custom field #8.

64

A user-defined string.

DEADBAND

The deadband set for a tag.

11

A numeric value (real) that indicates how much the value of a variable tag can fluctuate within a defined threshold without updates being sent through to the system.

The threshold is represented as a percentage of the tag's engineering range. The default value is 0 (zero), which captures every value change.

ENG_FULL

The engineering full scale point for a tag.

11

Numeric value (real).

This value represents engineering units. It is the upper limit used for trends and bar graphs.

It is a scaled value derived from the Raw Full Scale property.

ENG_UNITS

Engineering units.

8

The engineering units that the value represents.

The predefined values (see below) are in the Help.dbf in the bin directory, but the user may specify it as a free text:

%, Amps, deg, ft, ft/min, ft/s, ft/sec, gal, gal/h, gal/min, gal/s, gal/sec, Hz, kg, kg/h, kg/min, kg/s, kg/sec, km/h, kPa, kW, litres, lt, lt/h, lt/min, lt/s, lt/sec, m/min, m/s, m/sec, metres, Rev, Rev/h, RPM, t, t/h, Tonnes, Volts, Watts.

ENG_ZERO

The engineering zero scale for a tag.

11

Numeric value (real).

This value represents engineering units. It is the lower limit used for trends and bar graphs.

It is a scaled value derived from the Raw Zero Scale property.

EQUIPMENT

Equipment name.

254

The name of the piece of equipment with which the tag is associated.

This can be a name that represents a single piece of equipment, or a name that also reflects the location of the equipment within the equipment hierarchy (where a period (.) is used to indicate levels in the hierarchy).

FULLNAME

The full name of the variable tag.

254

The full name of the variable tag in the format:

<ClusterName>.<TagName>.

HISTORIAN

Determines if the alarm will be included in an automated configuration process within the Historian environment.

6

True or False (blank).

ITEM

Equipment item.

63

The name of an item with which the tag is associated.

Items form part of an equipment hierarchy. They can be used to associate tags, alarms and trends with a particular attribute of a physical piece of equipment.

RAW_FULL

The raw full scale for the tag.

11

Numeric value (real).

It is a raw value read from the I/O device. It represents the upper limit used by Plant SCADA to calculate scaled engineering values.

If not defined, Raw Zero Scale and Raw Full Scale will default to the full range value based on the data type.

RAW_ZERO

The raw zero scale for this value.

11

Numeric value (real).

It is a raw value read from the I/O device. It represents the lowest value used by Plant SCADA to calculate scaled engineering values.

If not defined, Raw Zero Scale and Raw Full Scale will default to the full range value based on the data type.

TAG

Tag name.

79

The configured tag name.

TYPE

Tag type string.

16

RDT_DIGITAL 0
RDT_INTEGER 1
RDT_REAL 2
RDT_BCD 3
RDT_LONG 4
RDT_LONG_BCD 5
RDT_STRING 7
RDT_BYTE 8
RDT_UINTEGER 10
RDT_ULONG 18

WRITE_ROLES

The roles that have write permissions for the variable tag.

254

Indicates which roles have write permissions for a variable tag when using an OPC UA or Industrial Graphics client.

Only users included in the specified role(s) will be able to send values to the variable tag from a client application.
