Download 6.0.6 | Build 6.0.6022.1250

Released: September 6, 2022

Version 6.0.6 is a bug-fix release, although we have included a few small enhancements:

• Improved error messaging from deployed data sources back to the Data Engines. This will help you troubleshoot issues with your data sources.
• Support for running Flow on Azure SQL Edge, the small-footprint, edge-optimized SQL database engine.
• Enabling calculated tags to evaluate despite dependent tags being deployed across disparate Data Engines, potentially running on disparate servers.

Release 6.0.0 | Build 6.0.0911.900

Released: May 20, 2022

Version 6.0.0 is a major release that includes a number of new features, performance enhancements and bug fixes:

Important

• From version 6.0.0 upwards, all Flow Integrations (i.e. Data Sources, Data Consumers, and Notification Services) will need to be deployed to a Flow Platform in the Deployment View. This change has been made to optimize communication with third party systems. It is advised that Flow Integrations are deployed on the servers running the respective third party systems where possible. For example, deploying a Canary Data Source to the Canary Server will optimize and streamline data transfer to Flow.
• From version 6.0.0 upwards, the Flow Mobile Notification Service will be deprecated. If you are still using Flow Mobile, please make sure you replace it as the Notification Service for all Message definitions that are using it. Alternative messaging apps that Flow supports include MS Teams, Slack and Telegram.

What's new?

Tags

• Tags represent the raw data passed through from a Data Source like a SQL Database query or a Historian tag. Tag data is made up of timestamp, value and quality "points".
• Tags are used for the following:
  • Measures, where primary aggregations can be configured (e.g. Time Weighted Average, Minimum, Maximum, Range, Counter, Time in State, etc.)
  • Calculated Tags, where multiple Tags can be used in calculation expressions. Points from each Tag are normalized by timestamp, value and quality ("point" normalized) and the calculation expression is applied to every row in the resulting data set ("row-based" calculation). User-Defined Functions can be used in Tag Calculations. Tags from different Data Sources can be combined in a Tag Calculations.
  • Pass-Through Charts, where both Tags and Calculated Tags can be displayed.
  • Public API, where both Tags and Calculated Tags can be requested.

Forms

• Forms are now located in the "Information" tab at the bottom right of Flow Config. This means they share a common "Information Model" and associated security configuration with Charts and Dashboards. This reduces duplicate folder security configurations that needed to be performed in previous versions.
• The configuration of a Form now has a similar look-and-feel to that of Charts. This also means Forms have additional formatting flexibility similar to what you have become accustomed to with Charts.
• Forms can now be configured using template Measures and Events, making Form configuration reusable.

Buffering

• Have you ever wanted Flow to access a real-time Data Source? Well, now you can with version 6.0.0's new buffering capability. Flow will buffer 7 days worth of raw data for use within Flow tags, measures and events.
• Flow buffering is currently available for experimentation via:
  • Telegraf, which has a number of input plugins, including protocols such as Modbus
  • MQTT, which supports both SparkplugB or Custom payloads
  • OPCUA 

Event Triggering

• Events can now be "projected", which is really useful if you want to access a production plan, or a maintenance schedule, or work orders into the future!
• Events that are triggered by SQL queries can now be configured with a "Refresh Trigger", allowing these Events to be automatically refreshed when their underlying data source is updated.

Dashboard Navigation

• Have you ever wanted a quick way to get from one dashboard to the next? Well, now you can with the new Navigation component. Use it to create links or buttons to other charts, forms, or dashboards!

Demo License

• Whenever you create a new Flow System, you will now have access to an automatically generated Demo License for 700 Tags, 500 Measures, and 10 Events for a period of 90 days.

Upgrading existing Flow Systems

Existing users must please note the following key steps before upgrading your Flow Systems:

Before Upgrading

• Undeploy all components using your existing Flow Config
• Perform a Database backup
• Stop the Flow Bootstrap Service
• Make a note of the Administrative user that is used to run the Flow Bootstrap Service

Technology updates to .Net Framework and .Net Core

If you're running Flow 5.4 or 5.5 you will have already installed these updates.  If not, then .Net Framework needs to be upgraded to version 4.8 and .Net Core to version 3.1. Here are some links to download and install these components:

• .Net Framework "Runtime" - https://dotnet.microsoft.com/download/dotnet-framework/net48
• .Net Core "Hosting Bundle" - https://dotnet.microsoft.com/download/dotnet/3.1

Installation and migration

• Run the Flow.msi installer you have downloaded
• Confirm the Flow Bootstrap Service's logon details are set to the Administrative user noted above
• Open Flow Config, select your Flow instance in the "Connect" dialog box, connect and then accept the migration process when prompted. If any error messages are received, please contact our support team.
• Deploy all components

NOTE: Changes to the Database schema and Private API

As always, with Major releases like this one, we may modify the Flow Database schema or Private API for performance improvements or for the addition of new functionality. In 6.0.0, we have modified the way Form configuration and data serving is handled. If you are accessing the Flow Database or Private API directly for either Form configuration or data, which we unfortunately do not support, you may need to modify those queries, or better still, migrate them to our public API. If you suspect this may be the case, please follow an upgrade testing procedure before migrating your production Flow system. And as always, make sure you backup your Flow Database before attempting any migration.
