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.

ADS can be used on top of either TCP or UDP, but ModbusTCP is always based on TCP/IP.
