getProtocolDevice

public ModbusProtocolDevice getProtocolDevice(String protocol)
                                       throws ModbusProtocolException

Description copied from interface: ModbusProtocolDeviceAcquisitionService

Gets the desired protocol interface if available. Search all installed field device protocols for a name matching the protocol.

Specified by:

getProtocolDevice in interface ModbusProtocolDeviceAcquisitionService

Parameters:

protocol - 'toString' name of desired protocol

Returns:

ProtocolDevice implementation of the selected protocol, ready to connect and use

Throws:

ModbusProtocolException

getProtocolDevice

public ModbusProtocolDevice getProtocolDevice(String protocol,
                                              Properties configureProtocol,
                                              Properties configureConnection,
                                              Properties configureDataMap)
                                       throws ModbusProtocolException

Description copied from interface: ModbusProtocolDeviceAcquisitionService

Gets the desired protocol interface if available and configures the interface. Search all installed field device protocols for a name matching the protocol, if found then attempt to configure the protocol.

Specified by:

getProtocolDevice in interface ModbusProtocolDeviceAcquisitionService

Parameters:

protocol - 'toString' name of desired protocol

configureProtocol - key/value paring directly from configuration file or may be generated.

configureConnection - key/value paring directly from configuration file or may be generated.

configureDataMap - key/value paring directly from configuration file or may be generated. Not all protocols require this configuration, this Dictionary may be null. If the selected protocol does require this configuration, a null Dictionary will cause the protocol to not configure and will throw a ProtocolConfigurationInvalidException.

Returns:

ProtocolDevice implementation of the selected protocol, ready to connect and use

Throws:

ModbusProtocolException
