k fuku Posted July 14, 2021 Report Share Posted July 14, 2021 PCログ取得時の通信速度変更と改善 デフォルトレイアウト表示時、PCリンクオンライン時の通信速度は50Hzです。レイアウトを表示した状態でPCログを起動すると25Hzまで低下します。 新しいレイアウトをクリックして、何も表示せずに PC ログを開始すると、理由はわかりませんが、約 40Hz でデータをログできます。 この症状は正常ですか? www.DeepL.com/Translator で翻訳 (無料版) Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 14, 2021 Report Share Posted July 14, 2021 The Hz value at the top right of the screen I believe is the "redraw rate" for the displayed PC Link data. This will get slower with more data displayed and slower when PC Link is doing other intensive work in the background such as logging. It is mostly related to the speed of the processor and graphics card in the PC - although if comms is slow then this redraw rate will drop also. Make sure all power saving features of the graphics card are disabled and it is always in "max performace" mode. Quote Link to comment Share on other sites More sharing options...
k fuku Posted July 14, 2021 Author Report Share Posted July 14, 2021 2021/7/15の午前6時56分に、アダムは次のように述べました。 画面右上のHz値は、表示されているPCリンクデータの「再描画率」だと思います。これは、より多くのデータが表示されると遅くなり、PCLinkがロギングなどの他の集中的な作業をバックグラウンドで実行している場合は遅くなります。これは主にPCのプロセッサとグラフィックカードの速度に関連していますが、通信が遅い場合、この再描画速度も低下します。 グラフィックカードのすべての省電力機能が無効になっていて、常に「最大パフォーマンス」モードになっていることを確認してください。 画面描写の速度の変化だけに加えて。PCログデータの実際の量は、通信速度の増加に比例して増加しました。 約2時間の実行例データ量が10Hzの35.000kbから40Hzの130.000kbに増加しました。 混合物のサンプル値も劇的に増加しました。 Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 15, 2021 Report Share Posted July 15, 2021 Sorry maybe I misunderstood your question. What are you changing? The connection speed setting? Or only changing the layout? Quote Link to comment Share on other sites More sharing options...

Connection settings USB Auto Low-speed connection enabled Communication speed 50 Hz during PC link online (No logging with basic layout in place) Turn off all layout displays during PC logging to increase communication speed. (50Hz) If you leave the layout displayed while logging, the communication speed will be severely reduced. (10Hz) The log data volume increased in proportion to the improvement of communication speed. Is this a bug or something? Translated with www.DeepL.com/Translator (free version) The communication speed changed depending on whether the layout was displayed or not, and the amount of log data increased in proportion to the increase in speed.

Yamamoto Posted July 16, 2021 Report Share Posted July 16, 2021 The PCLINK software uses a lot of CPU power to draw. This is often the reason for reducing the layout and making it faster. Please let me know the model and specifications of your PC. If the processing cannot keep up or if the CPU becomes hot and the frequency decreases, the sampling rate also decreases. And a little bit of a solution 1: Change the layout to something simpler. 2: Reduce unused parameters in PC logging. 3: ECU logging is used instead of PC logging. postscript For faster PCs, use the default layout in the Layout folder to output 60 Hz or higher when logging.

Adamw Posted July 16, 2021 Report Share Posted July 16, 2021 Yes, if you use slow connection speed mode then all functions in PC Link will be slower - this includes PC logging, screen redraw rate, storing to ecu, loading maps and downloading log files.
