3.7.2 Log downloading and analysis using a personal computer
Logs can be downloaded onto a personal computer using the pCO Manager software. Refer to the User
Manual of the pCO Manager for a description of the download procedure.
Alternatively, logs can be downloaded onto a USB pen drive following the procedure described above for board
programming. The only difference is selection of the item “Download (pCO-pen)” followed by the log file to be
downloaded.
In both cases a log in .csv format is downloaded. This is then read with the pCO Log Converter software by
Carel.
