Access machine configuration menu

Navigate to Setup → Machine → Configuration → Monitoring → CfgMonPreferences in the TNC control.

Use MOD function to access configuration mode if not already enabled

Check monitoringTasks array entries

Examine each entry in monitoringTasks[] array and verify that exactly four limit values are defined for each monitoring task.

Document existing values before making changes

Add missing limit parameters

Configure all four required limit values (typically warning low, alarm low, alarm high, warning high) for the affected monitoring task entry.

Reference machine manufacturer specifications for appropriate threshold values

Save and restart control

Save configuration changes and perform a control restart to activate the new monitoring task parameters.

Navigate to CfgMonComponent configuration

Access Setup → Machine → Configuration → Monitoring → CfgMonComponent in the TNC interface.

Use search function to quickly locate specific monitoring components

Verify limit value sequence

Check that limit values are arranged in ascending order: limit1 < limit2 < limit3 < limit4 for proper threshold operation.

Incorrect ordering can cause false alarms or missed monitoring events

Reorder limit parameters

Correct the sequence by adjusting limit values to maintain proper ascending order while preserving intended monitoring thresholds.

Validate configuration syntax

Use TNC configuration validation tools to verify proper parameter structure before saving changes.

Access CfgMonComponent display settings

Navigate to Setup → Machine → Configuration → Monitoring → CfgMonComponent and locate the display parameter entry.

Check if display parameter exists but contains null or empty values

Configure display parameter

Enter appropriate display configuration value specifying how the monitoring task should appear in the TNC operator interface.

Use only valid display format strings supported by your TNC version

Test display functionality

Verify that the monitoring task appears correctly in the TNC monitoring display after configuration changes.

Document display settings

Record the display configuration parameters for future reference and maintenance procedures.

Backup current configuration

Create complete backup of machine configuration using TNC backup function before attempting repairs.

Always backup before modifying configuration files

Reset monitoring configuration

Reset CfgMonPreferences and CfgMonComponent to factory defaults through Setup → Machine → Configuration reset function.

Restore monitoring parameters

Manually reconfigure monitoring tasks using documented machine parameters and manufacturer specifications.

Contact machine tool builder for original monitoring configuration values

Validate restored configuration

Test all monitoring functions to ensure proper operation after configuration restoration.
