Class ProtocolConnectionType

java.lang.Object

com.esf.protocol.fielddevice.service.ProtocolConnectionType

public class ProtocolConnectionType
extends java.lang.Object

This static class defines the various protocol connection types. Any connection not clearly fitting one of the provided types should be specified as the PROTOCOL_CONNECTION_TYPE_PROTOCOL_SPECIFIC.

The idea behind providing connection types is for future support of a protocol connection layer to unload some of the work from the individual protocol implementations.

Field Summary

Fields

Modifier and Type	Field and Description
static java.lang.String	PROTOCOL_CONNECTION_TYPE_ETHER_TCP protocol specifically connects using a TCP socket connection
static java.lang.String	PROTOCOL_CONNECTION_TYPE_ETHER_UDP protocol specifically connects using UDP datagrams
static java.lang.String	PROTOCOL_CONNECTION_TYPE_ETHERNET protocol connects over Ethernet.
static java.lang.String	PROTOCOL_CONNECTION_TYPE_NONE protocol specifically does not connect to a physical device.
static java.lang.String	PROTOCOL_CONNECTION_TYPE_PROTOCOL_SPECIFIC may be a custom connection, dedicated interface, or a connection standard type connection that it is known would never fit any form of standardized protocol connection support layer.
static java.lang.String	PROTOCOL_CONNECTION_TYPE_RS485 protocol uses a standard serial port specifically connected as RS485.
static java.lang.String	PROTOCOL_CONNECTION_TYPE_SERIAL protocol uses a standard serial port, may or may not use some form of handshake or extended control.

Field Detail

PROTOCOL_CONNECTION_TYPE_PROTOCOL_SPECIFIC

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_PROTOCOL_SPECIFIC

may be a custom connection, dedicated interface, or a connection standard type connection that it is known would never fit any form of standardized protocol connection support layer.

Constant Field Values

PROTOCOL_CONNECTION_TYPE_NONE

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_NONE

protocol specifically does not connect to a physical device. This type indication should never need to be used.

Constant Field Values

PROTOCOL_CONNECTION_TYPE_SERIAL

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_SERIAL

protocol uses a standard serial port, may or may not use some form of handshake or extended control. This may be used to indicate a port operating in 485 mode.

Constant Field Values

PROTOCOL_CONNECTION_TYPE_RS485

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_RS485

protocol uses a standard serial port specifically connected as RS485. Selecting this type over the basic serial type in a future protocol connection support layer may allow some simplification of the configuration for a 485 connection.

Constant Field Values

PROTOCOL_CONNECTION_TYPE_ETHERNET

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_ETHERNET

protocol connects over Ethernet. One of the more specific Ethernet type definitions should be used if applicable.

Constant Field Values

PROTOCOL_CONNECTION_TYPE_ETHER_TCP

public static final java.lang.String PROTOCOL_CONNECTION_TYPE_ETHER_TCP

protocol specifically connects using a TCP socket connection
