The graphic interface is filled with many simple but functional elements.

For more informations about customizing the HMI Panel, visit related Panels page.

# Indicators

Indicators are foundamental for every control panel. There are many different ones implemented into PlexusLAB, everyone has its own specific purpose to represent data inte the best way.

# Labels

They are used to identify the state of the associated variable. A coloured background helps to immediatly perceive the higlighted state.

labels

# Level bar

The progress bar represents the value of a measured variable changing between its minimum and maximum. This is a linear displacement and changes in real time with related variable.

progress_bar

# Gauge indicator

Gauge indicator represents a variable's value changing between its minimum and maximum. It uses an angular displacement that changes in real time with associated value.

gauge

# Buttons

A button allows to control the state of a boolean variable which can be only ON/OFF.

buttons

TIP

Buttons are usually related to digital I/O channels.

WARNING

A button can be disabled depending on system status.

Example: a process has started in automatic mode, so all manual controls over actuators are disabled.

# Field of values

Fields of values represent a variable value with numbers. They are divided into input and output fields:

# Output

Displays the value of an associated variable with it related units of measure.

field2

# Input

Allows to set the value of a system variable. They are usually important values used to change system status.
