Tag Groups

VTScada has tag groups that are used to organize the standard tag types into collections based on their value, capabilities, or other characteristics. Some of the tag types belong to multiple groups based on shared characteristics.

The tag groups enable selection of a specific tag type in a tag-associated drop-down list. For example, when creating a new driver tag type to be associated with an Analog Input or Digital Input tag, clicking the tag browser button to the right of the I/O Device field opens a group dialog from which you can select the type of driver tag you wish to create.

The analogs group assembles those tags that read or write analog (continuous floating point) values to a device.

The group is composed of the following members:

I/O and Calculations - Analog, Discrete, Numeric Calculation

Analog Control tags

Analog Input tags

Analog Output tags

Analog Status tags

Counter

Data Flow Pulse input
Calculation Selector Switch

Rate of Change

Totalizer

The container group is composed of those tags that can have contributors. (An example of a container/contributor relationship might be at a power generation station, where the container tag (also referred to as an owner tag) would calculate the overall power output for the entire station based on the value of its many contributor tags.)

The container group is composed of the following members:

Analog Statistics

Context

Data Flow RTU

Digital Statistics
Grundfos Dedicated Controls

MPE Duplexer Station

MPE SC Station

MultiSmart

Polling Driver

 Subordinate
   
   

The digitals group assembles those tags that read or write digital (discrete) values to an I/O device.

The group is composed of the following members:

I/O and Calculations - Analog, Discrete, Numeric Calculation

Alarm

Alarm priority

Data Flow RTU

Digital control

Digital input

Digital output

Digital status

Network status

Polling driver

Pump status
PLC Alarm Selector Switch

Roster

Trigger

The drivers group consists of tags that are used to provide an interface to physical I/O devices or to Windows system features, such as Dynamic Data Exchange.

The group is composed of the following members:

ABB TotalFlow BACnet Bristol BSAP/IBP Driver
Bristol BSAP/IBP Network CalAmp Diagnostic Campbell Scientific Array
Campbell Scientific PakBus CATM5X CSV
Data Flow System RTU DDE Client DNP3

OPC UA Client Polling Rockwell (Allen Bradley Devices)
Siemens S7 SNMP Managed Device SQL Data Query
Tesco Data Express Plus TI505 Toyopuc
Transaction Logger Veeder Root Workstation Status
     

The VTScada loggers group consists of tags that have a numeric value, and that can have their data logged to disk for data examination and analysis, and plotting on the Historical Data Viewer page by having a Historian tag associated with them, either directly or via a Logger tag.

In this case, it is easier to list the tags that are NOT members:

Alarm Database

Alarm Priority

Context

The Trenders group consists of tags whose value can be plotted on the Historical Data Viewer page. The tags composing the Trenders group are:

All drivers I/O and Calculations tag

When Trenders is selected in the Tag Browser's Types drop-down list, and the New button is clicked, the Trenders Group dialog will open, enabling you to select the type of tag you wish to create.

To create a new tag, select the radio button corresponding to the type of tag you wish to create, and then click OK. A new tag properties folder associated with the selected tag type will open for configuration.
