Structures ¶ CHCAddressComponent (Struct) CHCAddressType (Enum) CHCPeerAddress (Struct) CHCProtocolDataUnit (Struct)

CHCAddressComponent (STRUCT) ¶ TYPE CHCAddressComponent : STRUCT InOut: Name Type Components ARRAY [0..1] OF BYTE

CHCAddressType (ENUM) ¶ TYPE CHCAddressType : InOut: Name Initial Absolute 0 Relative 1

CHCPeerAddress (STRUCT) ¶ TYPE CHCPeerAddress : STRUCT InOut: Name Type Initial Comment dwStructSize DWORD SIZEOF(THIS^) addrType CHCAddressType / Determines whether the specified address is a relative OR an absolute address. nAddrOffset DINT Only valid, if type==AT_RELATIVE. Contains the negative number of address components to move up in the node tree, before going down the path specified in pAddress. (e.g. “-1” to move up one level). This field specifies the initial value of AdrIndex in router package header. nAddrLength UDINT Number of valid elements in array pointed to by pAddress nAddrComponentCount UDINT (SIZEOF(addrComponents) / SIZEOF(addrComponents[0])) For possible extensibility of further address components addrComponents ARRAY [0..(MAX_NODE_ADDR_LEN - 1)] OF CHCAddressComponent
