Communication Protocols
Integrate your equipment by utilizing one of our supported network and industrial communication protocols.
Control and Integration Interfaces
Dashboard Server
Interpreter Mode
Realtime Interface
Primary/Secondary Interface
XML-RPC
ROS/ROS2 Driver
Socket TCP/IP
Real-Time Data Exchange
Fieldbus Protocols
Modbus TCP/IP
The Modbus interface is a widely used communication protocol in the automation industry today.
EtherNet/IP
Ethernet/IP is another available Fieldbus on the UR. The robot can act as an Ethernet/IP Server but cannot act as Ethernet/IP Client.
SRCI
Standard Robot Command Interface (SRCI) is a command-based protocol, using PROFINET.
PROFINET/ProfiSafe
Profinet is a Fieldbus standard that utilizes TCP/IP and is based on Profibus.
