Hi,

Is it possible to write to an existing .txt or .csv file on the robot in order to create a log of sorts?

My idea is to record variable and time data for troubleshooting purposes. Things like:

- Program Start Time
- “Var\_1” = xxx
- “Var\_2” = xxx
- “Operation X completed”
- Program end Time

I’ve seen the use of txtmsg() in other posts, but would like to avoid saving to log\_history.txt if possible since it’s my understanding that it can be overwritten if file size exceeds a certain threshold. I would also like to avoid using a xmlrpc daemon as I don’t currently have hardware available or permissions to connect a PC.

Hello,

I have used this nifty program template from Robotiq to export variables to a PC in CSV format.

Hope it helps,
