Version 10.0.0 - December 15, 2021

External Historian Support - In addition to the built-in historian, DataHub can now store time series data to InfluxDB V1, InfluxDB V2, Influx Cloud, AVEVA Historian, AVEVA Insight, OSIsoft PI, REST servers and Amazon Kinesis.  Where applicable, these historians can be used for data visualization in QuickTrend and WebView, and for retrieval via OPC UA Historical Data Access.

Store-and-Forward for Historical Data, MQTT and Amazon Kinesis -  Time series data can be stored in InfluxDB and then forwarded to MQTT, Amazon Kinesis, or another historian through DataHub tunneling.  This ensures that data is transmitted even in the event of a network failure.

Tunneling Support for Historical Data - DataHub tunneling can now act as a transmission path for historical data.  This allows you to synchronize data from a protected operations network to a central historian without opening any incoming firewall ports in either the operations or IT networks.  Neither network is exposed to external attack due to DataHub's unique multi-hop historical data transmission technology, allowing historical data to reliably traverse a DMZ.

Installation of InfluxDB V1, Chronograf and Grafana - The DataHub installer includes a copy of InfluxDB community edition, Chronograf and Grafana, along with a user interface that allows you to quickly configure and launch each of these applications.  You can use the versions shipped in the DataHub installer, or connect to your own installation of InfluxDB locally, on your network, or in the cloud.

OPC UA Alarms and Conditions - DataHub now supports OPC UA A&C (Alarms and Conditions) client and server interfaces, and converts between OPC UA A&C and OPC Classic A&E.  This includes support for alarm acknowledgement, alarm source aggregation, tunneling and redundancy.

Alarm Generation - DataHub now implements sophisticated alarm generation. Specify different types of alarms, like multi-state, stateless and simple processing.  This includes the ability to generate OPC A&E and OPC A&C alarms from real-time data, including state lifecycle and acknowledgement.  The alarm generation system uses scripted conditions and actions to enable a wide variety of tests, such as multi-tag mathematics and sliding window statistical analysis (like variance, average and slope).  Alarms can be specified as patterns to match all similar devices in a system with a single configuration, allowing you to configure alarms for all your similar devices with a single configuration.

Notification of Alarms via SMS, Email and Social Media - The new notification system allows you to change data values, send email, call a web hook, or send any notification (SMS, WhatsApp, Line, etc.) supported by Twilio in response to an alarm.  This includes both alarms generated by the DataHub alarm generator and alarms generated externally by OPC A&E or A&C servers.

MQTT Speed and Scaling - DataHub version 10 replaces the MQTT client and server implementation with Mosquitto, a trusted high-speed MQTT library with excellent protocol support.  This allows the DataHub broker to simultaneously handle up to 5000 connections, with much lower CPU requirements than the version 9 implementation.

Sparkplug B for MQTT - DataHub's MQTT implementation now supports Sparkplug B.  This is a protocol layered on top of MQTT intended to provide plug-and-play interoperability among MQTT clients.  DataHub's broker not only supports Sparkplug B, but also adds capability to work around some limitations of Sparkplug B to help ensure that data representations are up to date and accurate under any network conditions.  DataHub MQTT client connections can act as Sparkplug B primary applications, non-primary applications or edge-of-network devices.  This allows you to easily convert any supported protocol to and from Sparkplug B.

Multiple JSON Format Support for MQTT - Most MQTT devices produce JSON messages, but with different JSON packet definitions. DataHub version 10 introduces support for any number of distinct JSON packet definitions using "JSON Schemas".  This allows you to define the kind of messages each type of device will generate, and DataHub will automatically determine which schema a message belongs to.  For each message schema you can define custom parsing and processing steps to extract data from any JSON message of any complexity.  You can also define how to format a message to write back to the device, even if the device expects messages in a format different from its output schema.

CSV Import for Data Point Configuration - Several DataHub features can now be partially configured through CSV files. This is particularly helpful when configuring a large number of OPC items for a connection.  Features supporting CSV import include: OPC UA client, OPC DA client, Bridging, MQTT client, Modbus and Historian.

WebView Undo/Redo and File Browser - Desktop WebView includes a number of enhancements, including Undo/Redo support for most editing operations.  In addition, WebView now includes a browser-based file browser that allows you to upload, arrange, modify and delete your WebView pages and assets on the DataHub server.
