Industrial Communication/Control Network Protocol Analyzer

Company Overview:

The Frontline family of protocol analysis tools represents 30+ years experience in wired and wireless communications analysis for industrial and commercial applications. In 2016, Frontline was acquired by Teledyne LeCroy, a leading manufacturer of advanced test instruments.

Product Overview:

NetDecoder is a PC-based industrial control network protocol analyzer/sniffer designed specifically to help isolate comm problems and reduce downtime with serial (RS-232/422/485), Ethernet (EtherNet/IP), and fieldbus devices and networks (DH+, DH-485, DeviceNet, ControlNet). Developed in close association with Rockwell Automation customers, it helps baseline, survey, and troubleshoot network and development issues. It provides network statistics, timestamped data bytes & control lead transitions, and decoded control protocol messages in plain language; live and in real time. Additional protocols/networks include DF1, PCCC, CSP, Modbus, DNP3, IEC-60870, and BSAP. Use NetDecoder to characterize network usage, isolate message or control lead timing issues, and analyze data messaging between devices during installation and start-up; review existing networks for optimization, expansion or replacement; and limit downtime by helping to isolate communication problems. An indispensable test tool for design engineers, system integrators, OEM development and test engineers, RTU troubleshooters, field service & maintenance engineers, and network engineers.
