LabVIEW Relay Timer Operation

In This Guide we will learn how to setup LabVIEW Relay Timer Operation, Pulse activated relay board and fixed time schedule relay.

A) Timer Calibration

This guide illustrates how to set Calibrate a timer and read back its calibration value.

Related Example in Driver: Timer Calibration.vi

VIs Required:

–> Initialize (Main Palette)

–> Calibrate (Timers Palette)

–> Read Calibration (Timers Palette)

–> Close (Main Palette)

Following figure shows the steps for this guide. Their detail follows the figure.

Details of steps is as under.

1. Port is initialized in Initialize VI with fixed baud rate of 115200.
2. Calibrate VI is placed. It sends the command to calibrate the timer and also verifies the returned status.
3. Read Calibration VI is placed. It reads back the calibration value which is displayed for the user.
4. Port is closed.
5. Text boxes for TX and RX data are placed and their references are passed to the Instrument VI which display the serial data sent and received by the instrument driver.

B) Simple Duration Timer

This example illustrates how to setup a Simple Pulse Timer (which activates with the command and does not require separate command for activation)

Note: It is assumed that the user has already calibrated the timer

Related Example in Driver: Simple Duration Timer.vi

VIs Required:

–> Initialize (Main Palette)

–> Enable Duration or Pulse Timer (Timers Palette)

–> Close (Main Palette)

Following figure shows the steps for this guide. Their detail follows the figure.

Details of steps is as under.

1. Port is initialized in Initialize VI with fixed baud rate of 115200.
2. Enable Duration or Pulse Timer VI is placed. It allows users to send multiple type of commands which are referenced in help for this VI.
3. Port is closed.
4. Text boxes for TX and RX data are placed and their references are passed to the Instrument VI which display the serial data sent and received by the instrument driver.
