Software: Canary Labs’ Trend Historian re-designed to maximize performance
Canary Labs, developer of historian software and tools, has redesigned its Canary Trend Historian product to ease the task of collecting, storing, managing, and automatically validating vast quantities of time series data. Available in either a 32-bit or 64-bit versions, Version 8.0 of the product is said to provide the industry’s highest capacities and throughputs.
For example, the writing performance on the Server exceeds 3.6 million updates (TVQs) per second, and the reading performance exceeds 13 million updates (TVQs) per second, said Gary Stern, Canary Labs president. Also, the 64-bit version is faster and provides increased addressable virtual memory capabilities to better handle large tag counts. The software handles 100 to more than 1 million tags and, since Trend Historian is a multi-threaded application, the number of clients supported is unlimited, he said.
"Due to the high performance of Canary Trend Historian, we do not have to implement compression techniques or limit display to selected data points to show fast trend chart data," said Stern. "Our compacting techniques allow raw data to be delivered quickly and accurately without compromising data integrity as is often the case with many other historians."
Trend Historian compacts the data to minimize the disk storage requirements, and the data stream from the Historian returns the exact data stream that was sent. For example, a typical sample includes a tag’s Time, Value & Quality (TVQ) data and is compacted to 4.5 to 6 bytes of disk space. Data resolution is 100ns with unicode support, and the logger application supports two forms of dead banding: absolute and percentage.
OPC-HDA compliant: Trending tools are OPC client and OPC-HDA server based solutions, tested and compliant with OPC specifications. The new OPC-UA standard will be supported within the next few months, said Stern.
Canary’s new functionality is reflective of growing interest in data-driven solutions and the infrastructure needed to support them. In fact, Jack Wilkins, Canary director of sales, said, "Canary is taking inquiries for channel partners on a worldwide basis, due to the increased demand we are seeing for robust trend historian solutions."
