Fieldbus system
Fig. 21: User Datagram Protocol (UDP)
Protocols running on top of TCP/IP and UDP/IP
The following protocols can run on top of TCP/IP or UDP:
• ADS
• ModbusTCP
Both of these protocols are implemented in parallel on the Bus Coupler, so that no configuration is needed to
activate the protocols.
Fig. 22: Protocols running on top of TCP/IP and UDP/IP
ADS can be used on top of either TCP or UDP, but ModbusTCP is always based on TCP/IP.
