2.產 品 詳 情 資 料：
NI PXI-7340伺服控制器卡否則，可以檢查輸出模塊上的狀態(tài)燈，然后在模塊端子板、系統(tǒng)端子板、機械端子板、電磁閥或繼電器連接等處進行電壓檢查，直到找到故障源。順序事件記錄器（SER），DOIO功能指令。這些可以設置為在接收到觸發(fā)信號時捕獲指定離散地址的狀態(tài)。它們可以用于監(jiān)視和捕獲程序某些部分的數據，即使在無人值守的情況下也是如此。它們可用于查找間歇性故障的原因。例如，NI PXI-7340保持線圈電源的一串觸點中的一個觸點可能會不時地瞬間斷開并中斷正常操作。然而，當維護人員試圖定位問題時，所有這些觸點可能測試正常。通過使用SER或DOIO指令，可以在故障發(fā)生后的毫秒內捕獲所有這些觸點的狀態(tài)，并且在捕獲時打開的觸點將顯示邏輯0的狀態(tài)。NI PXI-7340
it does not, the status light on the output module could be checked, then voltage checks could be made at the module terminal board, the system terminal strip, the machinery terminal strip, the solenoid or relay connections, etc. until the source of the fault is found. Sequential Event Recorder (SER), DOIO functional instructionNI PXI-7340These can be set up to capture the status of specified discrete addresses upon receiving a trigger signal. They may be used to monitor and capture data about certain portions of the program, even when unattended. They can be useful for locating the cause of an intermittent problem. For example, a contact in a string of contacts that maintain power to a coil may, from time to time, momentarily open and interrupt normal operation. However, when maintenance personnel attempt to locate the problem, all of these contacts may test OK. By using the SER or DOIO instruction, the status of all of these contacts can be captured within milliseconds of the time the fault occurs, and the contact that opened will show a status of logic 0 at the moment of capture.NI PXI-7340
