For errorcode definitions, refer to Section 9.6.2.Co nn ec tio n Stat us9.5 Programming9.5.1 Explicit MessageAll connections in EtherNet/IP can be divided into explicit messaging connections and implicit (or I/O) messagingconnections. Explicit messaging uses TCP/IP and request/response communications or client/server connections,requiring that the instruction include the memory location of the data to be sent to the client. Implicit messaging usesUDP/IP, in which a server sends information from predefined memory locations to a client at a given interval, using arequested packet interval (RPI) parameter to specify the interval. For details on using implicit messages, please refer toSection 9.4.4. This section provides an overview of how the AS Series uses explicit messaging instructions.When the AS Series acts a Scanner, you can use the EIPRW instruction (API 2208) to read and write Objects. When EIPBuilder uses Objects as parameters, each Object includes various parameters. For details on the EIPRW instruction,please refer to the AS Programming Manual. For details on Objects that are supported by the AS Series, please refer toSection 9.8.9.5.2 TAGEtherNet/IP can use TAGs to exchange data. A Delta PLC can use Global Symbols to define a TAG, and then Delta HMIand third party devices can use the TAG. There are 2 types of EIP TAGs, Produced TAGs and Consumed TAGs.1. Produced TAG: a PLC makes Produced tags that send data to Consumed tags in other EIP Scanners for datamapping with other EIP devices.Connection StatusError Codes
