Log file

Function
The log file is stored in the directory where the calling program is located. You can specify
the file name for the log file. The restrictions that apply to program names also apply here.
Only letters, numbers and underscores are permitted, and the name must commence with
two letters or a letter followed by an underscore. The file always has the extension "MPF".
The maximum length of the log file is limited in MD 11420: LEN_PROTOCOL_FILE. If the
system detects during writing that a data record is too long, another log file is automatically
created. Underscore and a digit are added to the name specified in _PROTNAME[1] and the
following message is output: "New log file has been created".
In this way, up to 9 subsequent logs can be stored in the control.
After the 10th log operation is halted and the following message is output: "Please specify
new log name".
After restart, operation is continued. If a log file with the same name already exists before
logging is started, then it is deleted before writing is started.
