Measurements Configuration Page

In the System Explorer window configuration tree, expand the Power Electronics Add-On (OPAL-RT Circuit) custom device and select Circuit >> Measurements to display this page.  After a model is successfully loaded in the Circuit Section, this page is added to the configuration tree and populated with a named list of the Measurement components found in the circuit model (as seen in Measurements Description). 

Measurements Section Channels

After a circuit has been loaded in the Circuit Section, the Measurements section of the configuration tree is populated with a list of custom device channels corresponding to each measurement component found in the circuit that has the Goes to VeriStand Channel option selected.

Open

These channels can be connected to other VeriStand channels in the project using the VeriStand Mapping Diagram.  Note that for any connections made in the Mapping Diagram, the data is passed through VeriStand channels on the Real Time CPU, resulting in increased latency and slower sampling rates than the rate at which data is generated on the FPGA. 

To view eHS Measurements in the VeriStand Workspace UI, the Waveforms feature can be used.

Measurements Description

Measurements are the output signals of the circuit model. They represent any measurement in the model and can be mapped to other components such as analog output channels, custom device channels, machines, waveforms, and more. In an electrical circuit diagram, a measurement can be read from the simulation by adding a Meter block in the circuit.

Most Meter blocks (and other measurements) will automatically create channels under the Measurements page. By default, the TO VERISTAND checkbox for Meters will be enabled which causes channels to be added in the page. Disabling the checkbox will supress the channels from being created.
