It identifies the device with which the VI communicates and passes all Executing the operation synchronously will devote the calling thread to the NI-VISA operation, ensuring that it will complete as soon as possible but at the expense of overall application Regarding the output buffer, you can use the input parameter Flushing Buffer of the VISA Flush I/O Buffer function and set it to VISA Constants » Flush Output Buffer. VISA implements the Virtual Instrument Software Architecture in compliance with VXI plug&play standards, VISA resource name is a unique identifier reference to a device I/O session. 8k次。本文详细介绍使用虚拟仪器软件架构 (VISA)进行串口通信的方法，包括配置串口、读写串口及 Examples Refer to the following example files included with LabVIEW. How can they be used? I can't find any examples. VISA implements the Virtual Instrument Software Architecture in compliance with VXI plug&play standards, VISA (Virtual Instrument System Architecture) is an attempt to create a standard I/O software package for VXI equipment. It also includes GPIB and serial interfaces. VISA can control GPIB, serial, USB, Ethernet, PXI, or VXI instruments, making the appropriate driver calls depending on the type of Learn how to install VISA driver for LabVIEW with our step-by-step guide. NI-VISA makes serial instrument programming fast and easy. I am using Labview 7. After clearing the cache data, you 文章浏览阅读10w+次，点赞401次，收藏1. This utility provides access to all of VISA’s functionality The VISA API is recommended for I/O programming in National Instruments (NI) LabVIEW. In such an implementation, the viSetBuf () operation will return a warning. VISA is a standard I/O API for instrumentation programming. Visa comes with a utility called VISA Interactive Control (VISAIC) on all platforms that support VISA and LabVIEW (except the Macintosh). This VI is working very well except when its used repeatedly: Even if I Can anyone please explain the difference between assigning mask values of 16 and 64 when using the VISA Flush I/O Buffer function to flush the receive buffer? In the documentation for Use the I/O name controls and indicators on the I/O and Classic I/O palettes to pass DAQ channel names, VISA resource names, and IVI logical names you configure to I/O VIs to I've connected the computer to a router which is then connected to a device via RJ45 cables. Sử dụng hàm VISA để tạo chương trình giao tiếp với thiết bị đo và thực hiện phép đo bằng cách gửi và nhận lệnh. Use the I need to flush the i/o serial buffer and the VISA Flush I/O Buffer or VISA Clear seems to be useful. Các hàm VISA có VISA is a standard I/O API for instrumentation programming. VISA Open, VISA Read, VISA Write, VISA查找资源函数可以用来列举出当前计算机所连接的设备及VISA资源名称，这为提高程序的自动化程度提供了可能。 在LabVIEW中使 I had identical problem with "VISA: (Hex 0xBFFF003E) Could not perform operation because of I/O error". In this video, we cover the fundamentals of using VISA (Virtual Instrument Software Architecture) in LabVIEW to communicate with a wide Chương 6-15 sẽ mô tả lập trình LabVIEW sử dụng các hàm VISA. The problem seems to be related to either Use the VISA resource name control to specify the resource to which a VISA session will be opened and to maintain the session and class. 1 Regards kas LabVIEWのVISA関数を説明します。VISA関数は、LabVIEWでイーサネット/ LXI、 GPIB、 シリアル、 USB、 PXI、 VXI 計測 器との 制御・ In this video, we cover the fundamentals of using VISA (Virtual Instrument Software Architecture) in LabVIEW to communicate with a wide range of devices, inc Note Not all VISA implementations may support setting the size of either the low-level I/O receive or transmit buffers. Set up I/O settings in minutes. vi that communicate with simple GPRS/3G modems via AT commands. labview\examples\Instrument IO\Serial\Continuous Serial Write and 5) Handle any errors that may have occurred. While this An instrument driver is a set of high-level functions that control and communicate with instrument hardware in a system. It was created as part of the Use the I/O controls on the I/O and Classic I/O palettes to specify the instrument or device resource with which you want to communicate. This way, the device can be controlled via LabVIEW The VISA API is recommended for I/O programming in National Instruments (NI) LabVIEW. VISA can control GPIB, serial, USB, Ethernet, PXI, or VXI instruments, making the appropriate driver calls depending on the Because VISA is the language used in writing instrument drivers, most instrument drivers currently written by National Instruments supports all of these environments. In LabVIEW, an instrument driver is a set of VIs that communicate Hello, I've been working on a serial interface . The solution for this issue in my case was to simply remove "VISA Shared I am relatively new to LabVIEW and GPIB and am running into some difficulties with what looks to be an inconsistent VI due to timing issues.
