自此，您可更快更准备地掌控网络：总线现在正常还是有隐患？是线缆或接头的问题，还是设备间的通信问题？为保持工厂的正常运行，此隐患需不需要紧急排除？ 通过一次简单的快速检测，该工具就可为您提供完整和清晰地答案。
单机模式诊断或者与电脑联机模式诊断
全能诊断仪既可连接PC机或笔记本电脑，也可单机运行。诊断结果显示在安装在电脑内的软件上，这样可轻松分析所有诊断细节，并可生成详细的书面报告。随附的PROFIBUS诊断工具全能软件，界面友好，方便使用。只需要点击一下鼠标，就可实现一个完整地测试与诊断。专家们偶尔需要地专业功能与标准功能独立开来，单独访问。
总线运行时，也可执行完整地诊断功能，而对总不产生任何的干扰和影响。该工具能可靠地检测出偶尔才出现的短暂故障与隐患。运用内置地主站仿真功能，在PLC未运行时就可诊断总线，– 比如，安装和调试期间，或疑似故障的设备需单独检测。该工具有助于减少总线的调试周期与非计划性停机时间。通过定期检测来实现预防性维护措施，以提高工厂的运行效率。

INTERVIEW
Fieldbus specialist Hans-Ludwig Göhringer
“Operator error is virtually eliminated |
Hans-Ludwig Göhringer, a seasoned fieldbus expert from Holzgerlingen in Germany, was one of the first to try out the new PROFIBUS Tester 4. In addition to on-site troubleshooting services, he regularly provides fieldbus training courses and heads a PROFIBUS International working group. In the interview he talks about the new tester:
Mr. Göhringer, what makes the new PROFIBUS Tester 4 different from all other testers?
Up until now I used to use several, separate testers for troubleshooting. Now I need just one. I don’t even have to take my notebook along everywhere. What is also very important in my line of work is to provide detailed test reports and handover documents as a reference for subsequent maintenance work. For this, the new Profibus tester delivers precisely reproducible test results for the signal quality of all bus devices. That’s something no other tester can do. My special focus is on EMC, so I highly appreciate that the unit features appropriate electrical isolation. Speaking from my own experience I cannot stress enough how important it is to use a bus tester with electrical isolation.
What advantages do you see for troubleshooting in general?
It takes just one click in the PC software to start testing, so operator error is virtually eliminated. This way even less experienced users can now finally carry out full, qualified tests. And that, in turn, makes remote diagnostics a lot easier for fieldbus experts like me. For example, it will often save us travel time and cost. Another point is that it used to be very difficult to find very rare faults because you had to permanently keep a notebook at the test location. Now, with the standalone mode, you can carry out long-term tests without a notebook.
What is your overall opinion on the new PROFIBUS Tester 4?
While people keep talking about Profinet etc., the majority of installations actually still use Profibus. And it looks as if Profibus will continue to be the most widespread fieldbus for a while – which means that it also has to be maintained throughout the lifetime of the installations. I am therefore very happy that a greatly improved Profibus tester is now available to make troubleshooting faster and more efficient. The possibility to test both bus physics and bus communication at the same time reveals completely new interrelations. In my opinion, the PROFIBUS Tester 4 will quickly become the all-in-one tool for troubleshooters like me and for maintenance staff. |
