Implement Phase 3: KRL Coordination
...
Complete implementation of Python-KRL coordination features for seamless
bidirectional communication between RSIPI and KUKA KRL programs.
## IOAPI Enhancements
Added high-level I/O control methods for convenient digital I/O manipulation:
- **set_output(channel, value, group='Digout')** - Set digital output by channel number
- **get_input(channel, group='Digin')** - Read digital input by channel number
- **pulse(channel, duration=0.1, group='Digout')** - Generate timed pulse on output
Benefits:
- Simpler channel-based addressing (channel 1 instead of 'Digout.o1')
- Automatic channel name formatting
- Built-in pulse generation for pneumatic actuators and signaling
- Consistent error handling
## KRLAPI Enhancements
Added coordination helper methods for Python-KRL synchronization:
- **wait_for_signal(channel, timeout=5.0)** - Block until KRL sets I/O signal
- **signal_complete(channel)** - Signal KRL that Python operation is complete
- **write_param(slot, value)** - Write to Tech.C variables (Python → KRL)
- **read_param(slot)** - Read from Tech.T variables (KRL → Python)
Features:
- Configurable timeouts with proper error handling
- Flexible slot addressing (11, 'C11', 'c11' all work)
- Slot validation (enforces 11-199 range)
- Comprehensive logging for debugging
- Clear docstrings with KRL code examples
## KRL Template Library
Created comprehensive KRL templates demonstrating coordination patterns:
**templates/krl/basic_handshake.src**
- Simple I/O handshaking (KRL signals → Python waits → Python signals back)
- Timeout handling and error recovery
- Complete Python code examples in comments
**templates/krl/parameter_passing.src**
