3.19.2.3 Uploading of record
The protection relay stores the load profile COMTRADE files to the
C:\LDP\COMTRADE folder. The files can be uploaded with the PCM600 tool or any
appropriate computer software that can access the C:\LDP\COMTRADE folder.
The load profile record consists of two COMTRADE file types: the configuration file
(.CFG) and the data file (.DAT). The file name is same for both file types.
To ensure that both the uploaded file types are generated from the same data
content, the files need to be uploaded successively. Once either of the files is
uploaded, the recording buffer is halted to give time to upload the other file.
Data content of the load profile record is sequentially updated.
Therefore, the size attribute for both COMTRADE files is "0".
