Access HSCI Configuration Parameters

Press MOD key, select 'Machine Parameters', navigate to MP7200 'HSCI Configuration' section.

Document current MP7200 values before making changes for rollback purposes.

Compare Configuration to Hardware

Check MP7200.0 through MP7200.15 entries against physical HSCI devices. Note HSCI addresses and device types from the alarm message variables %1 and %2.

Incorrect HSCI configuration can disable critical machine functions.

Update Missing Device Entries

Add missing device entries to appropriate MP7200.x parameters using correct device type codes and HSCI addresses shown in alarm details.

Restart Control System

Perform complete TNC restart (Ctrl+Alt+Del or power cycle) to reinitialize HSCI chain with updated configuration.

Check Hardware Options Parameter

Navigate to MP128 'Hardware Options' and verify bit settings correspond to installed HSCI hardware modules.

Cross-Reference with Hardware List

Compare MP128 bit pattern with actual installed options like additional axes, spindle modules, or I/O expansions in HSCI chain.

Correct Option Bits

Set appropriate bits in MP128 to match physical hardware configuration. Consult machine documentation for correct bit assignments.

Validate HSCI Chain Recognition

Restart TNC and verify HSCI devices are properly recognized in diagnostic display under 'System Info' > 'Hardware'.

Identify Extra Hardware

Use alarm message variables %2 to identify the HSCI address and serial number of the unconfigured device in the chain.

Physically Inspect HSCI Chain

Trace HSCI cables and verify all connected devices against machine documentation to locate unauthorized additions.

Power down machine before disconnecting HSCI devices to prevent damage.

Remove or Configure Extra Device

Either physically disconnect the unauthorized device or add proper configuration entries in MP7200 series if the device is intentionally installed.

Verify Chain Integrity

Restart TNC and confirm HSCI chain operates without alarm. Check that all configured devices respond properly.

Audit HSCI Address Assignments

Review all MP7200.x entries for duplicate HSCI addresses and compare with physical device address switches or settings.

Check Physical Device Addresses

Verify each HSCI device's physical address setting (DIP switches or rotary switches) matches its MP7200 configuration entry.

HSCI addresses must be unique and sequential starting from address 1.

Resolve Address Conflicts

Reassign conflicting addresses either by changing physical device settings or updating MP7200 parameters to create unique addressing.

Test HSCI Communication

Restart TNC and verify each device responds at its assigned address using diagnostic functions in 'Service' > 'HSCI Diagnostics'.
