"Get Date-Time String" element

Get Date-Time String

LabVIEW RT block diagram snippet: Open a datalog file, get onboard accelerometer measurement, log the measurement to a file, and close the file

Headless datalogger and file I/O
RT code

Monitor process variables and sensor measurements, timestamp them, and log them to a file, and then remote access the datalog file through the network with WebDAV, web browser, or VI running on a PC host.

LabVIEW RT block diagram snippet: RT checks for Internet access and then sends an email composed of recipients, subject line, and message

Send an email or text message
RT code

Use the Simple Mail Transport Protocol (SMTP) to send an email message; send the email to an SMS (Short Message Service) gateway service to forward the email as a text message.

LabVIEW RT block diagram snippet: RT opens a handle to SMTP email session, sets recipients, message, attachments, and headers, then sends the email message

Send a file as an email attachment with high priority (remote webcam photo logger application)
RT code

Use the low-level Simple Mail Transport Protocol (SMTP) VIs create an email, attach a file, and set the email header to flag the message as 'high priority' in the recipient's email application. The illustrative application example captures webcam images at regular intervals and sends them as email attachments.

LabVIEW RT block diagram snippet: Read the onboard accelerometer and pushbutton, convert to JSON string, and write to TCP channel

TCP client-server
RT code PC code

Create a server on the Academic RIO Device that listens for TCP/IP network connection requests from a client running on the PC host, accepts client information including the desired state of the four onboard LEDs, sets the LEDs accordingly, and returns the state of the onboard 3-axis accelerometer and pushbutton.

LabVIEW RT block diagram snippet: Read the onboard accelerometer and pushbutton, convert to JSON string, and write to UDP channel

UDP client-server
RT code PC code

Create a server on the Academic RIO Device that listens for UDP datagram messages from a client running on the PC host, accepts client information including the desired state of the four onboard LEDs, sets the LEDs accordingly, and returns the state of the onboard 3-axis accelerometer and pushbutton.

LabVIEW RT block diagram snippet: Control onboard LEDs from web form data, return system date/time

Host a Web service
RT code

Host a web service on the Academic RIO Device to serve the states of onboard sensors (pushbutton and accelerometer) and system information (date, time, host name, and IP address), and to control the onboard LEDs based on a user-selected LED hex code.
