ProXR is a standard set of relay control commands that allow users to control relays by sending bytes of data. Turn relays on or off, trigger timers, flashers, and control relay groups using the ProXR command set. This document will guide you through everything you need to know to start using NCD ProXR series controllers.

LabVIEW Relay switching and Status acquisition 1 In this LabVIEW relay switching article we will learn how to on off a relay, how to check relay status, bank status. These LabVIEW relay drivers will work with most of the ncd.io industrial relay controllers. which can be found over here Industrial Relay Controller For labview A) Setting a Relay ON/OFF and getting Status in Current Bank This guide shows how to turn a relay ON take status, then wait 5 seconds, turn it OFF and again take status. This VI handles relay in current bank which is set with another command.
LabVIEW Relay Controller Advanced Configuration In this LabVIEW Relay Controller Advanced Configuration guide we will learn how to set relay delay, read delay, set, read relay bank values and relay test bench. A) Set and Read Character Delay Value This guide illustrates how to set and read character delay value Related Example in Driver: Character Delay Configuration.vi VIs Required: –> Initialize (Main Palette) –> Set Character Delay (Configuration->Advanced Palette) –> Read Character Delay (Configuration->Advanced Palette) –> Close (Main Palette) Following figure shows the steps for this guide. Their detail follows the figure. Details of steps is as under. Port is
LabVIEW Relay controller Basic Configuration In this LabVIEW Relay controller Basic Configuration manual we will learn how to automatically and manually refresh the relays, how to set and relay relay bank, set and read default relay state. A) Automatic vs Manual Refresh This example illustrates how to Disable Automatic refreshing and refresh Relays Manually. Related Example in Driver: Relay Refreshing.vi It works as follows, Turns OFF automatic refreshing Reads back Refreshing Status to verify. Turns on Relay 2 and 3 in Bank 1, then waits 5 seconds Manually Refreshes Relays, again waits 5 seconds Turns on Automatic Relay Refreshing Turns
LabVIEW Relay switching and Status acquisition 2 In this LabVIEW Relay switching article we will learn how read relay status, set relay status and relay grouping. These LabVIEW relay drivers will work with most of the ncd.io industrial relay controllers. which can be found over here Industrial Relay Controller For labview A) Read Relay Status for 8 Relays This guide shows how to read status of all 8 relays in currently selected relay bank. Related Example in Driver: Read Relay Status 8 Relays.vi VIs Required: –> Initialize (Main Palette) –> Read Relay Status 8 Relays (Action Status->Advanced Palette) –> Close
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. Port is initialized in Initialize VI with fixed baud rate of 115200.
ProXR controllers have been the standard for relay control applications for many years. Over the years, we have improved firmware to add functionality. Several years ago, we migrated from a PIC16F690 processor to a PIC18F46K22 processor, which has more memory and runs 4 times faster. After this migration, we found it necessary to slow down the CPU to safer levels, as older software was not able to handle the ultra-low latency of the new CPU. NCD ProXR relay controllers have the ability to perform much faster by tuning a few settings. This guide will help you get the most performance
Introduction The NCD Component Library makes it easy to integrate ProXR controllers into Microsoft Visual Studio. The NCD Component Library is a complete command set that eliminates most of the detailed programming, allowing you to take control of ProXR controllers using high-level functions. With the NCD Component Library, you will receive over 40 samples from A/D Conversion to Duration and Pulse Timing and best of all, it’s FREE!! We want the user to be able to experiment with all the different samples available, so as of right now the samples cannot be downloaded individually. Quick Summary of NCD Component Library
