Moving Analog Indicator

Component Palette Icon

The Moving Analog Indicator is another component that fits well with the High Performance HMI techniques and practices. This component displays an analog value in context with other information about that value so that you can visually quickly see if the value is in the normal range or not. The current value is shown as an arrow pointing at a bar with segments showing the desired operating range, low and high alarm ranges, and interlock ranges.

The Moving Analog Indicator component allows for extremely fast information delivery. At a glance, it is obvious to an operator whether or not the value is where it should be, or if it needs attention. If the value is in one of its alarm ranges, then that range changes color to get attention.

To switch the Moving Analog Indicator between a horizontal vs vertical orientation, simply change the size so that it is either wide or tall, respectively. Typical setup of this component involves setting the ranges, and binding the Process Value property to a Tag's value. Some properties may be cleared out (null value) in order to disable them. For example, you may indicate where the current setpoint is by setting the Setpoint Value property. If you don't want to display the setpoint, simply clear this value out.
