Recent Updates

• Implementation Phase Complete: All core components have been implemented and are feature-complete

• Host Testing In Progress: ISDU, OD, and PD modules have passed initial host-based testing

• Target Testing Pending: Hardware validation on actual IO-Link devices is scheduled

Outstanding Issues

• Target hardware testing not yet initiated - requires physical IO-Link master and test setup

• IOLinke-Bindings require validation with C-based firmware integration

• Extended testing scenarios for edge cases and error conditions pending

• The current host testing architecture is unstable and may yield inconsistent results across runs.

Next Steps

Immediate Priorities

1. Target Hardware Testing

   • Set up physical test environment with IO-Link master

   • Validate ISDU transfers on actual hardware

   • Test PD and OD operations in real-world scenarios

2. Bindings Validation

   • Complete C binding integration tests

   • Validate FFI interface with sample C applications

3. Extended Testing

   • Add stress testing scenarios

   • Validate timing requirements per IO-Link v1.1.4 specification

   • Test interoperability with multiple IO-Link master implementations

Future Enhancements

• Establish a robust, configurable host testing framework to ensure consistent, repeatable test execution across diverse configurations and environments

• Implement diagnostic and monitoring features

• Create comprehensive integration test suite

• Develop automated hardware-in-the-loop (HIL) testing framework
