Support for Ethernet (for LAN), Real-Time UDP, and PTP IEEE-1588 (over UDP and TCP) is part of the on-board I/O connectivity of real-time target machines. A range of dedicated I/O modules are also available for further flexibility.

All solutions come with Simulink® driver blocks.

UDP, TCP, and PTP for Simulink

Selection Guide

IO715 4 ports Performance, Mobile and Baseline real-time target machine
IO716  1 port  Performance real-time target machine 
IO791 2 ports Mobile, Baseline, and Unit real-time target machine

These I/O modules also support EtherCAT Master and DNP3.

About PTP

The Precision Time Protocol (PTP) is a communications protocol that allows clocks to be synchronized over an Ethernet network. It is accurate to within one microsecond, making it suitable for control and distributed measurement.

Speedgoat supports the latest version of the protocol, known as PTP Version 2 or IEEE 1588-2008, which improves accuracy, precision and robustness compared with the previous version.

About Real-Time UDP

Real-time UDP (Universal Datagram Protocol) is a real-time version of the UDP protocol layered on top of the Internet Protocol (IP) and is commonly known as UDP/IP.

UDP can be used to connect your target machine to other nodes using a dedicated Gigabit Ethernet Card (real-time UDP), or by sharing the Ethernet port used for host-target communication. Sharing the Ethernet port has the disadvantage of decreased reliability, as error checking and recovering is limited if network traffic by other host-target communication tasks is heavy. Therefore Speedgoat strongly recommend using a dedicated Ethernet port for real-time UDP communication.
