1. The trend data overcomes the previous data after one month; I want to save the trend file. Which file should I save? ? 2. How can I view the trends on my personal computer after saving them? ? ? Please
Compress the monthly trend file directly, and then use offline queries to decompress the trend file in order to retrieve the trends
You can back up a month’s worth of historical data; there is a history.hsg file in the project files, which contains the records for each day. Create a file and save it there; it’s best to compress it, as historical files take up a lot of space. Create a file package each month. Then you can perform queries in the offline configuration search; within the offline configuration, you can use time filtering, and you can add the device tag numbers you want to search for to the list – usually up to 8 can be added. It’s the same as querying data online.
Look in the project’s HDB file
