Pie Chart

The Pie Chart function block can be used to create a pie chart for later use in the HMI Dashboard. The number of pie pieces can be parameterized via the parameterNum Channels.

Since the function of this function block is irrelevant for the analysis itself, it belongs to the Visualization Only category.

Optionally, a Boolean signal can be selected for the Enable Execution input so that the algorithm is only active if the value of the selected signal is TRUE.

Configuration options

• Num Channels: specifies the number of configurable channels. This corresponds to the number of pie pieces in the pie chart.
• Channel Name 00: specifies the name of the first channel. The name assigned here will later be used for this channel in the HMI Dashboard.
• Channel Name 01: specifies the name of the second channel. The name assigned here will later be used for this channel in the HMI Dashboard.
• Channel Name xx: analog for all other channels.

Standard HMI Controls

For the Pie Chart algorithm the following HMI controls are available for generating an Analytics Dashboard.

Pie Chart to display the data in a pie chart.

Histogram to display the data in a histogram.

Alternatively, customer-specific HMI controls can be mapped in the Pie Chart algorithm using the Mapping Wizard.
