How do you do serial communication in LabVIEW?

NI-VISA Driver Examples

1. To locate the example, open LabVIEW and navigate to the Help tab >> Find Examples >> Hardware Input and Output >> Serial >> Simple Serial.vi.
2. Ensure the proper VISA resource name is selected and the serial settings are correct.
3. Run the VI.
4. The Respond indicator should display the *IDN?\

Which type of serial communication can be implemented in LabVIEW?

However, LINX is only compatible with LabVIEW 2020 and newer versions. LabVIEW has the capability to use multiple types of serial communication, which is still often used in industrial equipment. To name a few, there are RS-232, RS-485, Modbus, Arduino, and Raspberry Pi.

Can communication using LabVIEW?

A Controller Area Network (CAN) bus is a high-integrity serial bus system for networking intelligent devices. Using a CAN interface device, you can write LabVIEW applications to communicate with a CAN network.

What is VISA in LabVIEW?

What Is VISA? VISA provides the programming interface between the hardware and development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio for Microsoft Visual Studio. NI-VISA is the National Instruments implementation of the VISA I/O standard.

What is VISA LabVIEW?

CAN communication programming?

The Controller Area Network (CAN) is a serial bus communications protocol developed by Bosch in the early 1980’s and is used as a standard for efficient and reliable communication between different nodes in industrial applications.

CAN communication basics?

The CAN communication protocol is a carrier-sense, multiple-access protocol with collision detection and arbitration on message priority (CSMA/CD+AMP). CSMA means that each node on a bus must wait for a prescribed period of inactivity before attempting to send a message.

What is the use of LabVIEW?

LabVIEW is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data insights.

How is the RS232 channel used in LabVIEW?

Communication functions in Labview. In order to use the RS232 communication channel the program must first claim its resources by “configuring” the channel. If the requested channel is free to be used then the program can either “write” to or “read” from the opened channel.

How to set up serial communication in LabVIEW?

If you are unable to see the COM port, refer to Serial COM Ports Missing in MAX or LabVIEW. Select the VISA resource and select the General tab. You can change the VISA Alias for easier identification. Select the Port Settings tab. Confirm the settings for baud rate, package size, stop bits, and parity bits are compliant with the instrument.

Why is RS232 used as a serial port?

Because of improvements in line drivers and cables, applications often increase the performance of RS232 beyond the distance and speed in the standards list. RS232 is limited to point-to-point connections between PC serial ports and devices.

Where to find the COM port on a ni serial device?

You should see the VISA resource name of the COM port listed as ASRL [board] [::INSTR]. If you are using an NI serial interface device, the COM port will appear under the interface. If you are unable to see the COM port, refer to Serial COM Ports Missing in MAX or LabVIEW.
