Canary Historian in Vietnam
TDL Industrial Automation is a Canary Certified Partner, listed on Canary Labs' partner page for Vietnam. The Canary System is a process historian with its own collectors, store and forward buffering, the Views asset layer and the Axiom client, licensed by tag count. TDL scopes the system, places collectors and store and forward on the plant network, and connects them to the PLCs, SCADA and servers that already hold the data.
The Canary System
Historian
Time-series storage in Canary's own database with lossless compression, organised in DataSets.
Collectors
OPC UA, OPC DA, MQTT (Sparkplug B and JSON), SQL, CSV and a module for Ignition. Canary states that collectors are not licensed separately.
Store and forward
Buffers values to local disk when the link to the Historian is lost and backfills them when it returns.
Views and Virtual Views
The gate for every client, with Virtual Views that rename tags and define assets without changing names at the source.
Axiom and Excel Add-in
Dashboards, trends and spreadsheet access. Canary's pricing page lists Axiom and Excel clients as unlimited.
Calcs & Events
KPIs per asset type and events such as downtime, batches and shifts, with backfill of past data.
How a Canary project with TDL is run
1. Tag list and sources
Which PLCs, SCADA servers, OPC servers or MQTT brokers hold the data, and how many tags will be logged now and in the next few years.
2. Collectors and buffering
Collectors and store and forward placed on or near each source, with disk space for buffering and the firewall openings between network levels.
3. DataSets and names
DataSets, tag names and Virtual Views agreed before data starts to build up.
4. Screens, KPIs and events
Axiom screens, calculations and event definitions agreed with the plant and checked on live data.
5. Outage test
A network outage tested on site to confirm that buffered data reaches the Historian when the link returns.
Experience so far
Historians on Rockwell Automation and AVEVA
FactoryTalk View SE with FactoryTalk Historian in a new-build feed plant, and AVEVA System Platform with historian and reports for facility monitoring.
Ignition and N3uron
TDL is an Ignition Certified Integrator and an N3uron Certified Integrator. Both platforms can send data to Canary: Ignition through Canary's module, N3uron over MQTT Sparkplug B.
Allen-Bradley controllers
Most plants TDL works in run ControlLogix and CompactLogix, which reach Canary through an OPC UA or OPC DA server, Ignition or N3uron.

Frequently Asked Questions
Is TDL a Canary partner?
Yes. TDL Industrial Automation is a Canary Certified Partner, listed on Canary Labs' partner page for Vietnam.
How is Canary licensed?
By the number of tags logged. Canary's pricing page lists Axiom and Excel clients as unlimited, and collectors come with the system without a separate licence.
Can Canary log Allen-Bradley PLCs?
Yes, through software that reads the PLC: an OPC UA or OPC DA server, an Ignition gateway with Canary's module, or N3uron publishing MQTT Sparkplug B. Canary has no collector that reads Logix controllers directly.
What happens if the network to the Historian goes down?
The store and forward service on the collector side buffers values to local disk and backfills the Historian when the link returns. By default it stops writing new values when only 4,000 MB of disk space remains.
