Macro reference

AddressNextDevice

	AddressNextDevice
Scans for the next connected device with a matching family code. Goes through the device list generated by the ScanBus macro.
- VOID	Return

GetSerialString

	GetSerialString
Gets the Serial String for the current addressed device.
- STRING	Return

Initialise

	Initialise
Configures each matching sensor on the bus with the specified conversion bits.
- VOID	Return

Property reference

	Properties
	One Wire Component
Link to the one wire component to host the bus.
	Simulation
	Simulate Comms
No - We use the panel GUI to perform the simulation. Yes - We use OneWire comms via an API to communicate with real hardware.
	Panel Simulation
	Number Devices
Sens the number of sensors we can communicate with during simulation
	Serial 0
Serial number for simulated one wire device
