每30秒记录一次34972A（通过USB连接）上4个通道的电压读数的程序（VEE ver.9.31）可以正常工作一两天，但之后会失去与仪器的联系。
与另一台PC上的.vxe文件的行为相同，只安装了运行时引擎。 记录的数据存储在.txt文件中。 这是唯一连接的仪器。 当这个故障发生时，它可以被连接专家看到 - 我可以从控制面板上随意互动。 但VEE表现得好像34972A改变了其Visa别名或者USB线已经掉线等等。我不得不重启.vee / .vxe程序。 有一次故障情况更糟 - 连连接专家都看不到34972A，我不得不重新启动它。 但是我没有在2014年3月17日上午7:17重新启动VEEEdited：Kevin001 以上来自于谷歌翻译 以下为原文 A program (VEE ver.9.31) which logs voltage readings from 4 channels on a 34972A (connected via USB) every 30 seconds works OK for a day or two but then loses contact with the instrument. Behaves the same with a .vxe file on another PC, on which only the runtime engine is installed. The logged data are stored in a .txt file. This is the only instrument connected. When this fault occurs it can be seen by connection expert - and I can interact as I please from the control panel. But VEE behaves as though the 34972A had changed its Visa alias or that the USB cable has fallen out etc. I had to restart the .vee/.vxe program. On one occasion the fault was worse - even connection expert couldn't see the 34972A and I had to power cycle it. But I didn't have to restart VEE Edited by: Kevin001 on Mar 17, 2014 7:17 AM

在运行程序之前，请确保已连接并配置仪器（绿色图标靠近vee上的仪器名称）。
或者您可以通过向连接专家发送简单查询来验证它，或者在Vee中您可以对仪器名称进行简单查询并选择“配置仪器”。 另一个可能的问题可能是您正在使用某个程序，其中没有使用您的仪器创建直接I / O对象，所以每次启动程序时，它似乎使用其他工具并且松开签证地址。 以上来自于谷歌翻译 以下为原文 Before running a program make sure your instrument is connected and configured (with the green icon close to the instrument name on vee). Or you can verify it by sending to him a simple query with the conection expert or in Vee you can right clic on the instrument name and select "configure instrument". Another possible problem may be that your are using someone program where direct I/O objet was not created with your instrument so each time time you launch the program it seem to use that other instrument and loose the visa adress. |

MAX_zuo 发表于 2019-1-7 16:17 正如我所说，系统每次启动时都会工作。 只有在数千个样本（总时间在一两天之间变化）之后才会出现问题。 它与采样率或数量无关。 没有动态改变仪器地址参数。 以上来自于谷歌翻译 以下为原文 As I said, the system works each time it is started. It is only after many thousand samples (the total time varies between a day or two) that the problem occurs. It's not related to the sample rate or number. There's nothing dynamically changing instrument address parameters. |

好吧，首先我建议更新到VEE 9.32和最新的directIO lib。
如果您在那里阅读自述文件，也许您可能会找到描述类似内容的内容。 并检查您的972的最新固件。 然后，如果错误仍然发生，有时你会在存储一个data.txt文件时出现问题，时间变化超过午夜 - 得到不同的名字......但我想也是关于USB设备 - 也许你有一个标志可以使用“ 关闭“通过驱动程序部分的操作系统 - 睡眠模式左右？ 以上来自于谷歌翻译 以下为原文 Well, first of all i recommend to update to VEE 9.32, and newest directIO lib. If you read the readme there, perhaps you may find something which describes similar thing. And check for newest firmware for your 972 , too. Then , if error still occurs, sometimes you make something wrong with the storage of a data.txt file of time changes over midnight- gets differnet name... But i think also about the USB device- perhaps you have a sign to use "power off" by operating system in the driver section - for sleep mode or so ? |

60user176 发表于 2019-1-7 16:38 谢谢你的建议。 上周，在我重新开始测试运行之前，我更新了A34972A的USB设备驱动程序（64位）。 该测试现已正常运行6天。 希望这是问题所在。 我将更新到VEE 9.32等，看看是否还好。问候，凯文 以上来自于谷歌翻译 以下为原文 Thanks for the suggestions. Last week, before I restarted the test run, I updated the USB device driver (64 bit) for the A34972A. The test has been running normally for 6 days now. Hopefully that was the problem. I shall update to VEE 9.32 etc. to see if still OK Regards, Kevin |
