The National Institute of Standards and Technology (NIST) introduces the Industrial Ethernet Network Performance (IENetP) test tool, an open-source solution for measuring and standardizing the real-time performance of EtherNet/IP devices in manufacturing environments. Developed with the Open DeviceNet Vendor Association (ODVA), this tool analyzes network data streams to identify timing deviations—or cyclic jitters—ensuring reliable communication for automation systems. For the full technical details, visit the NIST publication page.
