Look here for any special instructions when installing or upgrading your VTScada version.
Customers running 12.2.10 or 12.2.11 that use OPC UA Client drivers need to upgrade to 12.2.12
After upgrading to 12.2.10 or 12.2.11, non-analog (i.e. digital or discrete) tags using OPC UA Client drivers will not receive value updates. These tags will get their initial value but will not be updated when those values change.
Recommendation: We urge customers running 12.2.10 or 12.2.11 that have applications that rely on OPC UA Client drivers to upgrade to 12.2.12 as soon as possible or roll back to a prior version.
Please contact us if you require further clarification.

Customers Running 12.1.62 that Rely on Parameter Expressions in their Roster Tags Need to Upgrade to 12.1.63
After upgrading to 12.1.62, parameter expressions used to set the Method or Enabled fields in a Roster tag’s list of contacts will no longer update. The fields relying on parameter expressions will keep the last value they had prior to the upgrade.
Recommendation: We urge customers running 12.1.62 that have applications that rely on Rosters with parameter expressions to upgrade to 12.1.63 as soon as possible.

More Control for Managing Twilio Voice Recognition
Twilio Voice recognition was created in version 12.2.01 as a method for customers to minimize problems in the transmission of DTMF tones from their devices to Twilio. Depending upon your contract with Twilio, this may incur an additional data charge or not be necessary for your devices. In version 12.2.10 an option has been added to toggle this ability, with the default being disabled. If you have version 12.2.01 to 12.02.09 you are encouraged to review your communication needs to determine if this Twilio feature is required. If not, you may upgrade to the version 12.2.10 to reduce any possible additional charges from Twilio, depending upon your account.

Recent Chrome/Edge Update Can Prevent VIC Launch
A recent update to Chrome®, Edge®, and other Chromium®-based browsers prevents the VTScada Internet Client (VIC) from launching from those browsers.
- Known affected versions of Chrome and Edge include v130 and above.
- Known affected VTScada® versions include 12.1.01 to 12.1.56.
- Only affects the VIC.
- Does not affect Anywhere Clients and Mobile Internet Clients.
- Does not affect existing Windows® desktop shortcuts for the VIC.

Recommended Solution:
Step 1 – Update servers to version 12.1.57 or higher.
Step 2 – On each client PC, open the Thin Client launch page in the affected browser.
Step 3 – Choose the “Download VTScada Internet Client” button to update the installed VIC.
Or, if unable to update the VTScada version:
From the Thin Client launch page, choose the “Open VTScada Internet Client” button. When the VIC starts, the Server Address will start with “http//” or “https//”. Add a colon (i.e. “http://” or https://) and continue as normal. After correcting the URL, you can save a shortcut to the desktop by clicking “Save as” in the lower left corner of the VIC sign in dialog. Use this shortcut rather than launching from the browser. Or simply use a non-Chromium based browser like Firefox®.

Rare Alarm Activation Issue
Alarms could fail to activate in versions 12.1.37 to 12.1.40 for I/O tags configured as Digital or Discrete. This could happen if the tag was added or modified (in any version of VTScada) via the Export/Sync Tags or Manage Types panel with the IO tag’s DigitalAlarmTripOpt parameter left blank or cleared.
- Affected VTScada versions include 12.1.37 to 12.1.40 inclusive.
- Not an issue if I/O tags are configured via the Tag Browser.
Recommended Solution:
Customers running versions 12.1.37 to 12.1.40 (both inclusive) are urged to upgrade to version 12.1.57 or higher, particularly if they have used the Export/Sync Tags or Manage Types panel to make tag configuration changes.
