Tellus specializes in the implementation of Canary Labs Historian Software.

Tellus can provide integration and software services for Canary Lab Historian. Our specialty is in the use of MQTT as the data collector, but we can implement all platforms. We can implement Canary Lab's powerful tools for leverage your data; Axiom, asset models, regular expression filters and more. Implements can be done on local servers, your own Cloud servers, or Canary's Cloud service.


Tellus has deep experience with Opto 22 and the related software and hardware products and systems that go into a project. We provide individual or group training on a scheduled or short notice basis. We are flexible so that training can be done at your facility, our facility or a separate location. The following topics are ready for customized training classes, but we can train on many others as well.

Progressive Traditional

EPIC/RIO System PAC Control

GroovView PAC Display

Ignition Edge SNAP PAC System

NodeRed Modbus

MQTT Sparkplug

SQL and Database




Tellus can build a software solution for your Opto 22 based project. We use the tools that come built-in from Opto 22 such as PAC Project, CodeSys, NodeRed or groovView.

We can also expand capabilities by using other software such as SQL Server, MQTT, Python, Ignition, QT or other packages to meet the needs of the project.

If you happen to require a software package that we are not familiar with, we will become proficient with it on our own time or draw on expertise of one of our many partners and resources.

Tellus is primarily a software company. We do not build control panels, create drawings or design electrical controls.

Proof of Concept

Tellus can save you time and money by helping with proof of concept. We can quickly stage the essential aspects of a system. POC work can be done at your facility or ours, using your hardware or ours, or a mix of both.

You won't have to wait. We will get right on it!

On Site Service

Tellus can provide an engineer experienced with Opto 22 to help solve whatever issue you may be having. Work can be done on site or remote, either scheduled in advance or under emergency conditions. This type of work is typically on a Time, Materials and Expenses basis.
