Sankey diagram

The Sankey Diagram function block can be used to create a Sankey diagram for later use in the HMI Dashboard. A distinction is made between inflows and outflows. The number of inflows and outflows can be individually parameterized via the parameters Num Channels Inflow and Num Channels Outflow respectively.

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 Inflow: specifies the number of channels of inflows in the Sankey diagram.
• Num Channels Outflow: specifies the number of channels of outflows in the Sankey diagram.
• Channel Name Rest: specifies the name of the channel with which a possible rest value is to be designated. The name assigned here will be used later for this outflow in the HMI Dashboard.
• Channel Name Inflow 00: specifies the name of the first inflow channel. The name assigned here will be used later for this inflow in the HMI Dashboard.
• Channel Name Inflow xx: analog for all other inflow channels.
• Channel Name Outflow 00: specifies the name of the first outflow channel. The name assigned here will be used later for this outflow in the HMI Dashboard.
• Channel Name Outflow 01: specifies the name of the second outflow channel. The name assigned here will be used later for this outflow in the HMI Dashboard.
• Channel Name Outflow xx: analog for all other channels.

Standard HMI Controls

For the Sankey Diagram algorithm the following HMI control is available for generating an Analytics Dashboard.

Sankey chart to display the data.

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