Monitoring and Alarming

  • Monitoring and Alarm Generation with Your Computer
    Use a USB data acquisition system to generate alarms when a measured values exceed a certain threshold.

Before You Begin

Monitoring a process variable such as engine temperature or rotational velocity of a drive shaft is essential for automation processes; this allows for logic to be built into the control algorithm and can shut down the system if necessary. With this module, you can start monitoring an input signal (process variable) and illuminating a virtual LED in NI LabVIEW software if it surpasses a threshold. Prior to starting this module, review the Learn LabVIEW modules to understand the fundamentals of graphical programming.
