Histogram 1Ch

The Histogram 1Ch calculates the distribution of a single channel input value cyclically. It can be configured with minimal bin, maximal bin and the total amount of bins. The dimension of the output array is the number of bins + 2. Because values that are less than the minimal bin are stored in the first array element and values greater than the maximal bin are stored in the last array element.

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

• Histogram Mode: The operation mode of the histogram. A distinction is made between absolute and relative output. The latter can be used to display the percentage distribution.
• Min Binned: Minimum value to be analyzed.
• Max Binned: Maximum value to be analyzed.
• Bins: Total number of histogram classes to be calculated.
• Enable Display Names: Enable Histogram Display Names. This configuration is visible hidden in the property window.
• Histogram Display Names: Display names of the individual bins. This configuration is hidden in the Property window and is used for the HMI.

Output values

• Num Values: Indicates the total number of analyzed values for the distribution.
• Histogram: The histogram is displayed below the Num Values. If you move the cursor over the bars, you will see a tooltip with the value interval and the corresponding value of the histogram bin.

Standard HMI Controls

For the Histogram 1Ch algorithm, the following HMI controls are available for generating an Analytics Dashboard:

1. The Histogram control visualizes the output value Num Values.

2. The PieChart control visualizes the output value Num Values.

3. The Table Control or Multivalue Control visualizes all output values: Num Values, Histogram.

Alternatively, customer-specific HMI controls can be mapped in the Histogram 1Ch algorithm using the Mapping Wizard.
