Can FTP-access to field point log file interrupt the running program?
We have a problem where our factory process control program on a Field Pointer suddenly stops the process. We are running the development system on a PC, wich deploys the program on the Field point, with user interface on the PC. Quite often the process stops for no apparent reason. I'm not sure right now if the control program on the Field Point is still running or if it stops. We use FTP from a distant PC (over VPN) directly to the Field Point to check if the process is running, by looking for date and size of log files produced during running process. I've never opened och copied any log file during process run, because this I'm sure this would cause problems for new log entries to be written. But can the mere looking at the log folder via XP-pros ftp-functionality cause the Field Point to have problems writing data to a log file?
I'm not sure how windows XP pro handles "my network places" when it comes to FTP, it look that it keeps some kind of local copy of the folders, or at least the files opened.
Next version of the program will have only basic functionality on the Field Point, leaving logging etc. to another program on the PC, but right now we are stuck with this system.
