What's New...

With each new release, Trihedral makes VTScada more powerful, yet at the same time, easier to use. Explore each category to learn what new features are available.

If you have legacy applications that you want to run in the new version of VTScada, please take time to read the upgrade notes for every version between what you had been running and the current version. Depending on how your application was created, you may need to take certain steps to ensure that it will continue to run. See: Moving to the Current Version.

New Features in VTScada 12.1

Features for Operators and Developers:

SCADA Security Guidelines

A best-practices guide is included with every copy of VTScada. This is a stand-alone document (not part of these help files), which can be found in the Documents sub-folder of your installation folder.
(C:\VTScada\Documents\VTScada_Security_Guidelines_Manual.html

The manual provides guidance for installing, commissioning, verifying and maintaining the cybersecurity-certified capability of VTScada in accordance with applicable IEC 62443 cybersecurity standards.

Use the new WebSocket interface to connect to EV Charging stations running the Open Charge Point Protocol (12.1.37)

VTScada can be configured as a WebSocket server, allowing your custom modules to accept WebSocket connections.

This allows the new OCPP Driver tag to communicate with electric vehicle charging stations running at least OCPP version 1.6J

Idea Studio -> Tag Browser Improvement (12.1.37)

When linking tags in the Idea Studio, the Tag Browser will now reopen to the last-used location in the tag hierarchy (if one exists). The location is retained for each user doing configuration.

New Workstation Status Addresses (12.1.37)

More ways to monitor memory usage on your system: SystemTotalMemoryBytes, SystemUsedMemoryBytes, SystemUsedMemoryPercentage.

The Driver Redirect tag is now standard. (12.1.37)

Formerly available only to applications built on the Oil and Gas Layer, this container tag is now available for all applications. Driver Redirect Tag

Support for TLS 1.3 for both server and client TCP sockets. (12.1.30)

It remains the installation's responsibility to disable older protocol versions via the operating system as required.

Idea Studio Improvements (12.1.35)

When pasting a graphic into the Idea Studio, the new object will be placed wherever the cursor is currently located. In earlier versions it would be placed in the center of the screen.

The Idea Studio's "Open" dialog can be filtered for pages, widgets, or both (all). It will now remember your choice of filter for the next time you open an existing file.

Historical Data Viewer Improvements (12.1.35)

You now have a choice of text sizes when viewing a plot in the HDV.

The Thin Client/Server Setup dialog now separates servers and connection addresses. (12.1.30)

Easier to use and less prone to misconfiguration. Advanced techniques of server-specific lists, which once required custom code can now be created easily for those who need such things. Configure a VTScada Thin Client Server. Important: See notes in Moving to the Current Version

Improved identification of Driver Multiplexer tags on the Services page. (12.1.34)

The VTScada OPC UA client driver can successfully OpenSecureChannel with an OPC UA Server that does not respond with the corresponding RequestHandle. (12.1.35)

Greatly increased the number of recipes that can be exported to Excel. (12.1.30)

Up to 16,384 recipes can be exported.

Control Lock System (12.1.28)

Control Locks can be used to prevent use and operation of selected equipment via the VTScada screens. Control Locks

Control Tokens (12.1.28)

The Control Token system ensures that only one person at a time has control over a tag or set of tags. It is complimentary to the Control Locks system. Control Tokens

Alarm Suppression (12.1.28)

Separate tracking of alarms that are turned off by an expression or event versus alarms that disabled by a developer.Suppress Alarms

Recipe Import widget

For the convenience of those building their own recipe pages, this duplicates the features of the import button of the built-in Recipe Page. (12.1.30)

Driver Discovery in the Tag Browser (12.1.27)

Initially enabled only for BACnet devices. This will search the specified location on your network for available devices. Driver Discovery

Date and time selection for memory tags. (12.1.26)

Numeric Entry widgets can now be configured to prompt operators for a date and time associated with each value they type. You can use this to record data collected outside VTScada.

Select Before Operate mode for several control widgets (12.1.18)

Set Value Button and Set Value Hotbox have been renamed "Legacy Set Value (Button or Hotbox)".

The new Set Value Button and the updated Numeric Entry Widget have several enhancements including the ability to configure confirmation such that operators must arm the write using this button (or numeric entry), then press another button to either Execute or Cancel the operation.

Set Value Button Widget, Numeric Entry Widget, Execute / Cancel Button Widget

Input tags using the DNP3 driver will now record attributes such as Quality and Comm Failure (12.1.18)

These can be used in graphics and reports.

The Alarm tag now supports "Fail to Operate" and "Unexpected Change of State" modes. (12.1.18)

Applies only for Trip alarms and only when connected to an I/O & Calculations tag. Alarm Tag

The Tag Browser now supports filtering by I/O address. (12.1.17)

New security privileges protect access to the Service Status page, and the ability to switch servers.

Read strings from register-based addresses in PLCs such Delta and Modbus 12.1.17

Do so by setting the "String stored in registers" flag of the IO tag, along with specifying the length in bytes.

Tag names can now be displayed beside their value in the Historical Data Viewer and the Plot Data widgets. (12.1.15)

Updated License Management

After being activated on a workstation, a license cannot be used on another workstation until deactivated on the first. This eliminates the need for hardware locks.

Reset tag parameters to default values using a right-click. (12.1.14)

Applies only to parameters that have a default value

Toggle Switch Widgets for Digital Controls (12.1.13)

The switch widgets are not just for Selector Switch tags anymore; you can now use them for your digital I/O control tags. A new Toggle Button Widget is also available.

IEC-62443-4-1 Certification

VTScada’s Development Environment is now certified to be in compliance with IEC 62443 Security For Industrial Automation And Control Systems, Part 4-1: Secure Product Development Life-cycle Requirements.

Redesigned Roster Tags

Add a separate delay between each contact (or have none at all), and set rules for how many times one or more contacts should be tried before moving on to the next entry in the list.
Every roster can now configure its own timing for callout delays, etc.
Add up to 39 contacts in each roster. Roster Tags

A new security privilege just for Roster tags.

To allow roster configuration without granting the Tag Modify privilege, use the new Roster Contacts privilege instead of Manual Data or Tag Parameter View. Legacy applications will be updated to migrate existing accounts to use the new privilege.

Custom views of Roster contact lists (12.1.07)

(For advanced developers only) Expression code can now access an array of the contacts in each roster, displaying relevant information about each in a list that you create.

Enable or disable one or more contacts without needing to reopen the Roster's properties dialog

Alarm Notification call-outs using Voice over Internet Protocol (VoIP)

Use an analog telephone adapter (ATA) or your existing VoIP phone system to send voice alarm notifications to operators. Using VoIP for Alarm Notification

Improved Twilio Performance

You no longer need a VTScada account as part of your Twilio configuration. Security and performance have both been improved. Using Twilio for Alarm Notifications

Recipe & Batch Processing

Create recipes for batch processes and then run and monitor them from within VTScada. Recipes and Batch Processing

Updated Tag Browser

New and more powerful filtering tools make it easier to find your tags in a large application.

Authorized operators can now write to output tags directly from the Tag Browser. The Tag Browser

Updated VTScada Application Manager (12.1.08)

Applications in the VAM will now indicate their progress while loading and whether a restart is required before you can do further configuration work. The application loading indicator will be especially useful to those using a thin client connection.

Page Shuffle (12.1.03)

Create a slide show of pages. Page Shuffling

Camera Tag and Widget

This tag and widget work together to display the video feed from your network-connected cameras within any page. Camera Tag, Camera Viewer Widget

Web Browser Widget

Embed a selected website within any page using the Web Browser Widget. Navigation widgets allow controlled navigation to selected sites.

A Function Selector for those creating expressions

Use this to browse a portion of the VTScada function library for code to use in your expressions. The Function Selection dialog is available from any VTScada Expression Editor dialog. Function Selection Dialog

Programmers can add their own functions for use within the selector. Add Functions to Your Application's Library

Multiple connections from a TCP/IP or UDP/IP port

Where supported by the VTScada driver and the PLC, you can now enable multiple connections on a single TCP/IP or UDP/IP port. While radios support one TCP/IP or UDP/IP connection per device, PLCs in a plant can open dozens (depending on the PLC). This frees PLCs from the limitations of network speed and allows them to use intervals of free time to process outstanding comm messages and achieve up to ten times the throughput per second.

Drivers that support multiple TCP/IP connections include:

Multiple Monitors for VTScada Internet Clients (VICs)

VIC connections can be configured to use multiple monitors. Realm Display Setup Tags
(Note: The Anywhere Client runs within a browser and therefore cannot be divided.)

SQL View tags

For those using ODBC to query VTScada data. Select tags and data attributes that will be available in named views rather than needing to sift through all properties of all tags when building your queries. SQL View Tag

A new security privilege can restrict access to the main History table for those who have the Remote Data View privilege. (12.1.07)

The new privilege is labeled: Remote Tag Value / History Retrieve. The intent is to restrict access to only those SQL Views the account is authorized to view. For backward compatibility, all existing accounts that have Remote Data Access will be granted this new privilege.

Support for POST requests to the REST interface

Allows large queries. To prevent an extremely long query from taking up excessive time and memory, a query size limit is introduced, which defaults to 32KB.

Improved security for the SNMP agent.

Expanded SNMP V3 support improves security. SNMP Driver

Define a default sort key and direction for all alarm lists.

New application properties, AlarmListDefaultSortDir and AlarmListDefaultSortKey can be added to set a default sorting key and direction for all alarm lists except the History list.

Tag attributes available to ODBC queries

Value attribute such as Questionable and Manual Data can now be ready by the ODBC interface when querying VTScada.

Enhanced Rockwell Driver

Formerly CIP, this new driver allows switching between Rockwell device protocols and modes to best suit the need, resulting in significantly faster performance.

Further updated in 12.1.10 to include a PLC Mode that connects to the 1756-DHRIO's DH+ channels, sending DF1 messages directly to the target PLCs. This provides support for customers using older PLC-5 and SLC controllers using routed PCCC over CIP through 1756-DHRIO Interface Modules.

New Delta Driver

As part of the Delta Electrics family, VTScada is being integrated with their hardware around the world. To facilitate this, 12.1 includes a dedicated driver for Delta’s Modbus-based PLCs and VFDs. To maximize throughput, this driver supports multiple PLC port connections.

Faster Installer

VTScada’s new installer is 27% smaller and 18% faster.

Script Bubbles

While VTScada already supports dedicated threads, version 12.1 allows script code to run in parallel “Bubbles” across all PC cores. (For example, the Modbus driver now runs in its own bubble.) The effect on performance is like running multiple copies of VTScada at once.

On-Screen Keyboard Support

Touchscreen PCs are now commonplace and have begun to replace single purpose Operator Interface Terminals (OITs). VTScada seamlessly supports the native Windows onscreen keyboard. Touchscreens

MultiSpeak® Support

The MultiSpeak® protocol facilitates data exchange between SCADA and various services required by electric utilities, such as outage management. Version 12.1 supports a variety of methods required by the Milsoft™ DisSPatch™ outage management system. MultiSpeak Support

Overall Total Report

Similar to the Hourly Total and the Daily Total reports, this calculates an overall total for total for the specified time period.
(Note that the X-Total reports are for values that accumulate, such as pump starts, and do not calculate things like total flow given a flow rate. For that, use a Totalizer tag.) Note that for these to calculate a total for an accumulator that rolls over each time a maximum is reached, you must specify that rollover value in the included tags' scaling parameters.

Choose whether new Tag Widgets get Tag Icon Markers and the Operator Controls menu.

When creating a new Tag Widget, you are likely to remove the Tag Icon Marker and disable the various operator controls. Now you can choose to exclude those features

Alarm Details dialog updated

The Alarm Details dialog now includes entries for both the time when an alarm normalized and when it was acknowledged. (This information has always been available in the History list.) Alarm Details Dialog

Export alarm lists from the Anywhere client (12.1.05)

When the Alarm Page is viewed in a VTScada Anywhere client, the "Copy to Clipboard" button is replaced by an "Export to CSV file" button.

I/O Tags will now write manual data values (12.1.06)

This applies only if the tag has an output address, and only if the person setting the manual data value has the security privilege configured for the tag.

Security roles at the root level can now be made visible in realms. (12.1.26)

Reduces the number of roles required by sharing base role descriptions between realms. Must be enabled on a role-by-role basis.

The BACnet driver can now import tags from your device. (12.1.06)

Additional drivers, including Enron Modbus, CAT M5X, GE Series 90, Honeywell Mercury, Fisher ROC, IEC 6087, and the ABB Totalflow, now show address information in the Address column of the Tag Browser. (12.1.10)

VTScada now supports a user interface in Traditional or Simplified Chinese, in addition to English and French.

The Source Debugger toolbar now includes a View Source button. (12.1.13)

If the source code is available for the module you are viewing, click this to open the file using your default editor.

Oil & Gas Layer Improvements (12.1.16)

When importing gas composition results from a file in the Oil and Gas Solutions layer, the Heating Value is now imported along with the rest of the results if it is available

Non-translatable parameters (12.1.16)

Parameters that you add to your pages and widgets can now be set as non-translatable. This is especially appropriate when the parameter is an I/O address.

Priority 0 (Event) alarms on I/O tags are now logged when they clear as well as when they trigger. (12.1.26)

 

New and changed tags

ABB Totalflow Driver No longer requires a third party service.

Alarms on Discrete I/O tags can now be triggered by state or upon change.

GE Series 90 Addressing The GE Series 90 driver now supports %G (bit) and %GY (byte) addressing.
History Statistics Tag Includes two new statistics: Change in Value and Change in Value with Rollover.
Honeywell Mercury Driver This driver can communicate with several types of Honeywell Mercury flow computer devices.
Modbus Compatible Device Driver

Redesigned so that I/O reads run on a separate core, resulting in greater responsiveness and the ability to handle large applications when using Modbus.

Now uses a common Modbus Transport service for sending communications, which allows for 16-bit addresses.

Also supports multiple TCP/IP port connections between a single instance of the driver and the RTU.

Motorola ACE Driver When viewed in the Tag Browser, the RTU ID value configured in this driver will be shown as the address. (12.1.26)
MultiSmart Station The MultiSmart station can now support up to nine pumps in two wells.
Multi-Write Tags You can now disable event logging for multi-writes that trigger automatically.
Rockwell Driver Tag

This is an updated and improved version of the CIP/ENIP Driver tag.

For those using DH+ networks, this tag will support Allen Bradley data file addressing via DF1 commands. These commands can then be routed via the PCCC protocol to communicate with PLC5, SLC and Micrologix PLCS that are connected to Control Logix gateways.

12.1.28: CIP message building has been standardized. Extensive cleanup of the related documentation.

Recipe Book Tag Holds a set of ingredients to be used for batch processing.
Recipe Ingredient Tag Holds the description and quantity of an ingredient to be used in a recipe.
