Siemens 840D 61352 - Channel Block: Path for logfile not permitted
Channel Block: Path for logfile not permitted
The alarm is triggerd by the following cycles: CYCLE106. The specified path for the log file is incorrect. Remedy: Check parameter _PROTNAME[1].
Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Common Causes
- Incorrect or invalid path syntax in _PROTNAME[1] parameter
- Insufficient file system permissions for the specified log file directory
- Path directory does not exist on the controller or connected storage
- Special characters or spaces in path name causing parsing errors
- Network drive or shared folder path inaccessible or disconnected
Troubleshooting Steps
- 1Verify the _PROTNAME[1] parameter value in the active program or machine data and confirm the path syntax is correct for the operating system
- 2Check that the target directory exists and is accessible from the CNC controller; create the directory if necessary
- 3Confirm file system permissions allow the CNC controller user account to read and write to the specified directory
- 4Remove any spaces, special characters, or invalid path delimiters from the _PROTNAME[1] path string
- 5If using network paths, verify the connection is active and the share is mounted; test with a local path first to isolate the issue
