自此，您可更快更準備地掌控網絡：總線現在正常還是有隱患？是線纜或接頭的問題，還是設備間的通信問題？為保持工廠的正常運行，此隱患需不需要緊急排除？ 通過一次簡單的快速檢測，該工具就可為您提供完整和清晰地答案。
單機模式診斷或者與電腦聯機模式診斷
全能診斷儀既可連接PC機或筆記本電腦，也可單機運行。診斷結果顯示在安裝在電腦內的軟件上，這樣可輕松分析所有診斷細節，并可生成詳細的書面報告。隨附的PROFIBUS診斷工具全能軟件，界面友好，方便使用。只需要點擊一下鼠標，就可實現一個完整地測試與診斷。專家們偶爾需要地專業功能與標準功能獨立開來，單獨訪問。
總線運行時，也可執行完整地診斷功能，而對總不產生任何的干擾和影響。該工具能可靠地檢測出偶爾才出現的短暫故障與隱患。運用內置地主站仿真功能，在PLC未運行時就可診斷總線，– 比如，安裝和調試期間，或疑似故障的設備需單獨檢測。該工具有助于減少總線的調試周期與非計劃性停機時間。通過定期檢測來實現預防性維護措施，以提高工廠的運行效率。
全能診斷儀功能一覽：自動檢測波特率、非擾動電壓（開路電壓）、物理層和協議層同步進行的標準檢測、主站仿真、拓樸掃描、測試報告自動生成、項目和網絡管理、報文分析、示波器波形分析、觸發輸入和輸出。 |

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. |
