	PVCiPressureGauge (Integer address, ModbusConnector connection) throws IOException
Float	getPressure () throws WrappedModbusException, ModbusException, IOException

Detailed Description

Contains an implementation of the PVCi IGC3 ion pressure gauge

The serial port parameters are hard-coded for now. More customization will come from a proper kernel, once that gets written.

Definition at line 22 of file PVCiPressureGauge.java.

Constructor & Destructor Documentation

devices.PVCiPressureGauge.PVCiPressureGauge	(	Integer	address,
		ModbusConnector	connection
	)		throws IOException

Instantiate a pressure gauge, and check that it is alive.

Parameters

address	The device address, numbered from 1 to 99. MODBUS requests are sent to the device with this address.
connection	The connection manager to use.

        this.address = address;

        log.debug(
                "Created PVCi pressure gauge with address {} and conn {}",
                address, connection);

        try {

            throw new IOException(error);
        }
    }

Member Function Documentation

Float devices.PVCiPressureGauge.getPressure

(

)

throws WrappedModbusException, ModbusException, IOException

Returns

The current pressure, in millibars.

Exceptions

WrappedModbusException	If the getter to get the transaction for the request fails
ModbusException	If the transaction to get the pressure cannot be executed
IOException	If the result of the transaction to get pressure cannot be parsed
