IPAddressSet (FB) ¶ FUNCTION_BLOCK FINAL IPAddressSet IMPLEMENTS IIPAddressSet , IIPAddressSet_Internal Represents a set of IIPAddress instances Static initialization, as shown in the following code snippet. VAR myFirstPublisher : NBS.IPv4Address := ( ipAddress := '224.0.100.20' ); mySecondPublisher : NBS.IPv4Address := ( ipAddress := '224.0.100.30' ); myPublisherSet : ARRAY [0..1] OF NBS.IIPAddress := [myFirstPublisher, mySecondPublisher] ; myMulticastSet : NBS.IPAddressSet := ( paitfIPAddress := ADR ( myPublisherSet [0] ), udiSize := SIZEOF ( myPublisherSet )); END_VAR InOut: Scope Name Type Comment Input Const paitfIPAddress POINTER TO ARRAY [0..0] OF IIPAddress The address of the first array element udiSize UDINT Size of the array paitfIPAddress is pointing to

UDP_Send (FB) ¶ FUNCTION_BLOCK PUBLIC FINAL UDP_Send EXTENDS ETrigTo This function block serves to sent data from the local itfPeer to the other side, specified by itfIPAddress and uiPort . The content of the memory area indicated by the pointer pData contains the data to be written. udiSize defines the number of bytes to be written. When xDone is set to TRUE , udiCount bytes of the data was written successfully. The time out value has no effect at this function block.
