BytesAvailableToRead

UDINT

Read

Indicates the number of bytes in the receive buffer available to be read using the Receive method. (Range: 0 ... 2147483647)

IsReadable

BOOL

Read

Indicates that data has been received that has not yet been processed by the Receive method.

IsWritable

BOOL

Read

Indicates that the connection is in a state where data can be sent to the server.

Result

ET_Result

Read

Indicates the result of the last method call.

If the result is different than Ok, the value is not overwritten not even a method is called.

State

ET_State

Read

Indicates the state of the socket.

TotalBytesReceived

ULINT

Read

Counts the total number of bytes received. (Range: 1 ... 2⁶⁴-1)

TotalBytesSent

ULINT

Read

Counts the total number of bytes sent. (Range: 1 ... 2⁶⁴-1)

SockOpt_Broadcast

BOOL

Read/write

Allows you to send broadcast packets via that UDP socket. If FALSE, the Send method returns an error message when sending UDP broadcast messages.

SockOpt_MulticastDefaultInterface

STRING(15)]

Read/write

Allows you to specify the IP address of the interface that is used to send multicast messages when no action has been performed that caused the socket to be bound.

SockOpt_MulticastLoopback

BOOL

Read/write

If set to TRUE, multicast messages sent are also copied to the receive buffer as if they had been sent by an external UDP peer.

SockOpt_MulticastTTL

SINT

Read/write

Specifies the time to live (TTL) of multicast messages sent. This value can affect the scope of where the packages are forwarded to. (Range: 0 ... 255)

SockOpt_ReceiveBufferSize

UDINT

Read/write

Sets the receive buffer size of the UDP stack. It should always be greater than the amount of data received at one time to help avoid data loss. (Range: 1 ... 2147483647)

SockOpt_SendBufferSize

UDINT

Read/write

Sets the send buffer size of the UDP stack. It should always be greater than the amount of data sent at one time to help avoid errors. (Range: 1 ... 2147483647)
