Profibus Analysis & Test Tools

NestTest II is a high-tech Profibus line analysis test device – no more nerve-racking and expensive search for installation errors in Profibus segments. NestTest II represents the 2nd generation of hand-held Profibus test tools developed by Comsoft. It provides an immediate, extensive report, revealing errors of installation and fitting in Profibus segments. NestTest II's field of application is not restricted to diagnostics in running systems. One of the main purposes of NestTest II is to allow the installer to check – directly after the installation - whether he has made any installation errors. Therefore, sporadic errors caused by incorrect bus physics can be excluded from the very beginning. NestTest II gives information on: short circuit, cable rupture or broken shield, mixed up cables, wrong number of terminations, not powered terminations, not terminated cables, tap lines, cable length, line impedance, inhomogeneous cables in the segment, Profibus baud rate, Profibus live list, participant selective RS
