The Horner series OCS units can be set up to periodically log to a uSD card.
This will generate a series of files with a new file generated each day.
The files are in a CSV format so can be opened with a spread sheet program.
The uSD card is not as convenient to transfer files as a USB stick and the XL4 has a USB port that can accept a USB stick.
To access the USB stick, the file name must be prefixed with 'B:\' and the file name must comply with the 8.3 file naming used in the DOS days.
The attached program shows how to copy all the files from a 'logs' directory on the uSD card to a 'logs' directory on the USB stick.
The copy operation is triggered by pressing the F1 key.
Note : the attached file is made using CScape version 9.7 SP2 so you will need to use this version of CScape or later.
