176 • Fieldbus Communication ETHERNET 4.1.3.2 Communication Protocols In addition to the ETHERNET standard, the following important communication protocols are implemented in the WAGO ETHERNET based (programmable) fieldbus couplers and controllers: • IP Version 4 (Raw-IP and IP-Multicast ) • TCP • UDP • ARP The following diagram is intended to explain the data structure of these protocols and how the data packets of the communication protocols ETHERNET, TCP and IP with the adapted application protocol MODBUS nested in each other for transmission. A detailed description of the tasks and addressing schemes of these protocols is contained in the following. Fig. 4-8: Communication Protocols e G012907 WAGO-I/O-SYSTEM 750 BACnet/IP Controller
