MXD70 Series – SD Card Data Logging with Live Trending
The Data logging additional software function expands the capabilities of the MXD70 series by allowing the user to record over time the status of the instrument. It consists of two separate sections, Live Trending and SD Card Data Logging, which together help the user to analyse and improve the performance of their application.
The MXD70 series features optional software functions which when purchased will expand the instrument’s capabilities. These functions by default are locked. They can be unlocked by LTH or your local distributor at the time of order. Alternatively the functions may be ordered after purchase by supplying LTH or your local distributor the serial number of your instrument. In return they will supply you with an 8 digit unlock code that is unique to the instrument and the required function to be unlocked.
Live Trending provides the user with three separate live trend screens adjacent to the front screen with each showing two readings. This enables the user to instantly view the last 50 samples of each reading. The live trend screen also features a review mode where by the user can further analyse the last 200 samples of each reading, If the user finds something of note the software provides the facility to save these 200 readings to an excel compatible file on the SD card.
Further analysis is provided by optionally displaying the minimum, maximum and average value of the 200 samples. The number of readings, the source of the readings, the displayed scale and the sample interval rate are all configurable by the user.
The SD Card Data Logging enables the user to log over long periods the status of the instrument. Variables logged include: the primary sensor readings, any secondary readings, set point status, the current output readings, digital input status and any error messages. This data can be viewed either on the MXD70 series instrument or removed and viewed in Microsoft Excel on a PC. The user can configure which channels are logged and the logging interval. When logging three inputs at one sample per second a 1GB card will allow 40 days of recording.
Once removed place the SD card in a card reader connected to the PC. Open the SD card in the file explorer and browse to either the Data logging folder to view the SD card data logging or the Live Trend folder to view the live trend log saves.
Each file is limited to 65535 logs; when this limit is reached the instrument will automatically create a new file. The instrument will also automatically create a new file if the configuration of the instrument is changed whilst the data logging is active. Each file name contains the date and time of when it was created. The data is stored as a comma separated variable (csv), which can be read by Microsoft Excel.
