Detailed Description
PLC Boolean Input Signal - Represents a boolean input signal from PLC to simulation.
PLCInputBool is a fundamental signal type for receiving boolean (true/false) data from external PLC systems into the Unity simulation environment. This component serves as a digital input point that can be read and monitored by simulation components to react to PLC control logic.
Key Features:
- Receives boolean values from connected PLC systems via various industrial protocols
- Supports real-time value changes with event notification system
- Provides edge detection for rising (false to true) and falling (true to false) transitions
- Implements override capability for manual testing and debugging without PLC connection
- Maintains connection status to indicate communication health with PLC
Signal Direction: PLC → Simulation (Input from PLC perspective) The signal flows from the PLC controller into the Unity simulation, allowing PLC programs to control simulation behavior through boolean states such as start/stop commands, sensor states, or status flags.
Common Applications:
- Receiving start/stop commands from PLC programs
- Reading digital sensor states (proximity sensors, light barriers, limit switches)
- Monitoring PLC status flags and operation modes
- Triggering simulation events based on PLC conditions
- Implementing safety interlocks and emergency stop signals
Interface Integration: PLCInputBool seamlessly integrates with multiple industrial communication protocols including:
- OPC UA: Maps to OPC UA boolean nodes for standardized communication
- S7 TCP/IP: Direct integration with Siemens S7 PLCs via TCP/IP
- Modbus TCP/RTU: Maps to Modbus coil or discrete input registers
- TwinCAT ADS: Connects to Beckhoff TwinCAT boolean variables
- MQTT: Subscribes to MQTT topics for IoT integration
- Shared Memory: High-speed local communication for virtual commissioning
Update Mechanism: The signal value is updated in FixedUpdate() to ensure consistent timing with Unity's physics system. Value changes trigger the EventSignalChanged event, allowing other components to react immediately. Edge detection (ChangedToTrue/ChangedToFalse) provides single-frame flags for transition handling, essential for implementing one-shot logic and state machines in automation sequences.
