Enterprise Historian

The Canary Enterprise Historian has been used in applications ranging from 100 tags to over 1 million tags, demonstrating scalability without the need for special computing hardware. It has the capability to log more than 3.6 million updates per second, easily meeting the requirements of high speed applications. The Enterprise Historian can log from any data source that meets the OPC DA (Data Access) specification. Enterprise Historian itself is an OPC HDA (Historical Data Access) compliant server, allowing you to use other OPC HDA compliant programs to access the data.

Using the Enterprise Historian Administrator tool any historian on your network can be monitored and configured from a single location. Administrative features such as automatic dataset validation, archiving, roll over and roll up, audit trails, and performance monitoring make the Enterprise Historian capable of running in a complex enterprise environment. Multiple Enterprise Historians can be used for redundancy and high data availability needs.

Canary Logger

The Canary Logger logs data from any OPC Data Access interface. OPC is the most prevalent standard in the industry with over 400 participating organizations. There are many third-party applications that support the OPC DA standards, allowing almost any PLC or device to be interfaced with the Canary Logger. In a distributed network application, The Canary Logger can run on various data collection machines and send the historical data back to a centralized network server for storage.

When the Canary Logger is logging to a remote Historian Service and the connection is lost for a period of time, the Logger will start caching the data in memory. It will then automatically try to re-establish the connection back to the Enterprise Historian. When a successful connection is made, it will send the data that has been cached. The amount of trend data that can be cached in memory depends on the number of tags and the physical memory in the logger PC. This feature protects the integrity of the trend data, should a short-term communication failure occur.

The Logger Administrator is an easy to use tool that makes logging configuration setup fast and easy. Using the Logger Administrator, a user creates logging groups that define which tags will be logged and where they will be logged in the Enterprise Historian. Tags can easily be added to a logging group by a simple click. A list of available tags in the OPC server is presented in a dialog box, where the user can select the tags to be added into the group.
