Access HSCI configuration menu

Navigate to MOD > System Parameters > HSCI Configuration to view current hardware status and detected components.

Document the current configuration before making changes

Perform hardware detection scan

Execute automatic hardware detection via HSCI menu to identify all connected components and generate new hardware fingerprint.

Ensure all HSCI devices are powered and connected before scanning

Update and save configuration

Accept the new hardware configuration and save to generate updated checksum. Reset alarm via PLC > Reset > HSCI Alarms.

Backup the new configuration to CF card after successful update

Inspect HSCI cable connections

Check all HSCI cable connections at encoders, drives, and TNC control for proper seating and physical damage.

Power down system before disconnecting HSCI cables

Test cable continuity

Use multimeter to verify continuity on HSCI cable pairs (typically pins 1-2 for data, 3-4 for clock) and check for shorts between pairs.

HSCI cables should show 120 ohm impedance between differential pairs

Reseat connections and test

Reconnect all HSCI cables firmly, power up system, and monitor HSCI status in MOD > Diagnostics > HSCI Status for stable communication.

Use HSCI diagnostic LEDs on modules to verify communication status

Verify HSCI termination settings

Check that only the last device in each HSCI chain has termination enabled via DIP switches or software configuration.

Typical HSCI termination is 120 ohms at chain endpoints only

Measure bus impedance

With system powered down, measure HSCI bus impedance between differential pairs - should read approximately 60 ohms with proper termination.

Incorrect termination can damage HSCI transceivers

Reconfigure termination and restart

Correct termination settings, power cycle the complete HSCI system, and verify stable operation via HSCI status monitoring.

Document termination settings for each HSCI node for future reference

Measure HSCI supply voltages

Check +5V and +24V supply voltages at HSCI modules under load - should be within ±5% tolerance with minimal ripple.

Use oscilloscope to check for voltage spikes during machine operation

Verify power supply capacity

Calculate total HSCI power consumption and verify power supply has adequate capacity with 20% safety margin.

Undersized power supplies can cause intermittent failures and component damage

Stabilize power and test system

Address power supply issues, add filtering if needed, and monitor HSCI system stability via continuous operation test.

Install power supply monitoring to detect future voltage excursions
