IFM - CR1081 *.cvs file read.

Found out an other way for my task, just made an array in the retain memory, and write it to usb too.

IFM - CR1081 *.cvs file read.

Hello, as the title says, I'm using a IFM CR1081 panel, and write string array to an cvs file. But I can't seem to find out how to read it from the storage of the panel. I do not wish to split the text line into several lines, only 1. Using Timestamp AND 'Sensor ' AND a number that indicates which sensor that has trigged.

Read/Write to the panel from the USB flash drive is ready, the only thing that I need is to actually read the *.cvs file that I recieve from the USB-storage.

So, writing from the panel into *.cvs file, to the USB-Flash drive, then automatically back to the panel, and read it and show it in a table is what I want to do.
