The PROFIBUS diagnostic tools provide solutions that range from mobile testing through to continuous monitoring of PROFIBUS systems. All the tools can be controlled with just one application - the new PROFIBUS Diagnostics Suite. This universal PC software is easy and intuitive to use and allows display and analysis of all the test data. The software supports all current and future diagnostic tools from Softing, including the new PROFIBUS Tester 4, which is the first to combine both bus physics and bus communication test capabilities in one device.
