Access MOD function configuration

Press MOD key, select 'Hardware configuration' from the menu, then navigate to HSCI device configuration section.

Always backup current configuration before making changes using the data backup function.

Verify HSCI device settings

Check the configured device type at the HSCI address shown in alarm parameter %3. Compare with the actual hardware device type from parameter %2.

Do not modify HSCI addresses while the control is running or devices are active.

Correct device configuration

Update the device type configuration to match the actual hardware. Select the correct device from the available HSCI device list.

Use the 'Auto-detect' function if available to automatically identify connected HSCI devices.

Restart control system

Perform a complete control restart to reinitialize the HSCI chain with the corrected configuration.

Ensure all programs are saved and machine is in safe position before restart.

Identify replaced hardware

Check the HSCI address from alarm parameter %3 and physically verify what device is actually connected at that position in the HSCI chain.

Document all HSCI device serial numbers and types for future reference.

Access hardware configuration

Enter MOD mode, navigate to 'System parameters' then 'Hardware configuration' to access HSCI device settings.

Only qualified personnel should modify hardware configurations.

Update device type configuration

Change the configured device type at the affected HSCI address to match the newly installed hardware device type.

Cross-reference device part numbers with Heidenhain documentation to ensure correct device type selection.

Verify HSCI chain integrity

Use the HSCI diagnostic function to test communication with all devices in the chain after configuration update.

Check HSCI address assignments

Review all HSCI device addresses in MOD hardware configuration to identify duplicate or conflicting address assignments.

Each HSCI device must have a unique address within the chain.

Verify physical device addresses

Check DIP switches or rotary switches on physical HSCI devices to confirm their hardware-set addresses match the configuration.

Use a systematic approach, checking addresses sequentially from 0 upward.

Resolve address conflicts

Reassign conflicting HSCI addresses either in software configuration or by changing physical device address settings.

Power down the control before changing physical address switches on HSCI devices.

Test HSCI communication

Use the TNC diagnostic functions to verify proper communication with all HSCI devices after address correction.

Backup current configuration

Create a backup of current settings using MOD data management functions before attempting any configuration restoration.

Save backup to external media to prevent data loss during restoration process.

Reset hardware configuration

Access MOD system parameters and use the 'Reset hardware configuration' function to clear corrupted settings.

This will reset all hardware configurations to default values.

Reconfigure HSCI devices

Manually reconfigure each HSCI device in the chain using the correct device types and addresses based on physical hardware.

Refer to machine documentation or previous configuration backups for correct device assignments.

Validate configuration

Test all HSCI devices functionality and verify proper communication before returning machine to production use.
