Master  
   

  1. In CANopen Master Library, there are two functions to add CANopen slave control, AddNode and EDS_Load. What is the difference with these two functions?
  2. Why the CPMUtility can not find the I-7565-CPM?
  3. Why the system information of WinPAC Utility can not find the I-87123 on the WinPAC?
  4. When I-87123 and other I-87k I/O module put on the WinPAC, why it need call I87123_Pause before the program accesses I-87k I/O and call I87123_Start after completed the access?
  5. How the Com Port of I-7565-CPM on Linux mapping ? And what should pay attention to initialize I-7565-CPM?(

  1. CANopen Master函式庫中新增slave站號的方式有AddNode與EDS_Load兩種，請問有甚麼差異？

  3. 為什麼WinPAC Utility的系統資訊找不到插在上面的I-87123模組？
  4. 當I-87123與其他I-87k I/O模組插在同一台WinPAC上時，為什麼要讀取I-87k I/O時需要先呼叫I87123_Pause，讀取完I/O後還要呼叫I87123_Start，這兩個函式是做什麼用的？
  5. I-7565-CPM在Linux上使用的Com Port是多少，要注意什麼?

GW-7433D

  2. How to update the GW-7433D firmware?
  3. Why the GW-7433D can't send any CAN message after setting by GW-7433D Utility?
    (the wire connection and baud rate setting are correctly)
  4. Why the GW-7433D often appear error code 47 after some time and then the GW-7433D can't receive the CANopen slave data?
  5. How SDO communication is initiated on CAN side? Does it send command when a Modbus TCP command register is updated or on any flag or data change event?
  6. Does the gateway support storage of received PDOs in order to capture them? How much is buffer size & how it informs the Modbus TCP master about availability of updated data in the buffer?
  7. GW-7433D will start to communication with CANopen devices after boot. Because some CANopen devices on our network need more time to ready, and it may cause some unknown issue. Is there any function can start/stop the communication of GW-7433D?
  8. When I set the GW-7433D from "Normal Mode" to "Listen Only". I see proper activity on the indicators however all Modbus addresses freeze in the last state. Is the "Listen Only" working correctly?
  9. Why the CANopen slave often appears "Buffer Overflow" error after boot-up with GW-7433D?

  1. 如何更改GW-7433D的IP位址？
  2. 如何更新GW-7433D的韌體？
  3. 我使用GW-7433D Utility設定GW-7433D完成之後，為何GW-7433D無法收送任何CAN命令？
    (CAN bus是有正確接上的，7段顯示器顯示的CAN Baud rate也是正確的，ERR Led有亮)
  4. 我的CANopen Slave設備與GW-7433D連線時一開始是正常的，為何總是在經過一小段時間後GW-7433D就無法接收到CAN data並顯示與Slave斷線的錯誤碼47？
  5. GW-7433D的Modbus TCP與CAN端的TxSDO與RxSDO是如何運作的？
  6. GW-7433D會儲存PDO的資料嗎？它有多少緩衝區？當CANopen的資料被更新了，它如何通知Modbus TCP主站的？
  7. GW-7433D在一開完機之後就會開始通訊，但因為CANopen slave需要比較長的開機時間，這會導致slave有不可預期的錯誤發生，有沒有什麼方法可以避免這個問題？
  8. 當我用Modbus命令設定GW-7433D為聆聽模式後，所有的Modbus資料都不再更新了，這樣是正確的嗎？
  9. 我的CANopen Slave設備與GW-7433D一起開機後，CANopen slave常常會發生Buffer Overflow的錯誤狀態，這是什麼原因？該怎麼處理？
