Getting Started with PowerDNA Explorer - Part 1

What is PowerDNA Explorer

PowerDNA Explorer is UEI’s GUI-based application for communicating with a RACK or Cube system. You can use it to view the Modules on your network, explore the individual Interface Boards available in each Module, and exercise the functionality of your UEI technology.

PowerDNA Explorer supports every UEI I/O Interface Layer, including the ability to acquire data, generate output, and otherwise employ Layer-specific features, without requiring the use of our API. The goal of this series is to cover the usage of PowerDNA Explorer over our entire product range.


AI-202: Measuring Current

To begin, we’ll look at the AI-202 Interface Board. This is a 12-channel, differential Analog Input Layer designed to measure current over multiple input ranges. Below, you can see the steps to reading amperage from an AI-202 using PowerDNA Explorer.

Figure 1-1 PowerDNA Explorer Initial Bootup

PowerDNA Explorer will scan the network immediately after being opened.

On the left side of the divider, you can see a list of all UEI I/O Modules that were discovered, as well as the Host machine the application is running on. Here, the only Module found was IOM_10238, a demoUEI Cube.

On the right side you will see information about the currently selected module: the Host PC in this case. This display will change to reflect your selection.

Figure 1-2 Layer Display and Tools

Expanding a discovered Module will display a list of the I/O Interface Layers contained within. Like the Modules themselves, these are selectable.

When a Layer is selected on the left, the right will change to display a list of information about the layer in question, a depiction of the Module, and a set of tools for interacting with the Layer.

Figure 1-3 Configuring Layer

The Al-202 Interface Layer (selected above) has three available input ranges to choose from. Use the dropdown menu to select one before measuring current.

Decreasing Input Range will increase measurement accuracy.

Figure 1-4 AI-202 Data Acquisition

Once you have selected the Module and Layer you want to work with, and configured the Layer’s settings, you can begin acquiring data.

In this case, the AI-202 will read differential current values from each of its 12 channels within a 0.15A range.


Similar Tools

There are Layers similar in function to the AI-202. The above instructions can also be used to set up data acquisition on the following layers:

  • The AI-205 is a 4-channel Analog Input Layer that measures voltage at a maximum range of±100V.

  • The AI-217 is a 17-channel (16 differential channels, 1 single-ended CJC channel) Analog Input Layer that measures voltage at a maximum range of ±10V

  • The AI-218 is an 8-channel Analog Input Layer that measures voltage at a maximum range of±10V

  • The AI-228-300 is an 8-channel Analog Input Layer that measures voltage at a maximum range of ±300V


AI-201-100: Differential vs Single-ended Channels

Figure 2-1 AI-201-100 Data Acquisition

The AI-201-100 is a 24-channel Analog Input Layer that measures voltage at a maximum range of ±15V. It has 24 single-ended channels, and 12 differential channels (the first 12 can be either).

There is an additional column in the table labeled “Differential”. Toggle the checkboxes here or use the master control above to switch between single-ended and differential measurement.


AI-204: Circuit Breaker Functionality

Figure 3-1 AI-204 Data Acquisition

The AI-204 is a 24-channel Analog Input Layer that measures current at a maximum range of ±0.025A. It also has circuit-breaker that can be configured from PowerDNA Explorer. The breakers will trip if the channel’s Input Current exceeds the Input Range for more than 100ms.

Using the Explorer Application, you can toggle circuit-breakers on a per-channel basis. Additionally, you can determine the status of the Layer’s circuit-breakers and reset them in the case of a trip.
