EDICTvb.Net allows you to easily create advanced process calculations that use PI Tags as equation inputs and outputs.

Solution Overview

Programmers and non-programmers can easily use our Equation Editor to define the logic and arithmetic needed for their equations. EDICTvb.Net will then build a compiled Microsoft Visual Basic .Net program that contains the necessary PI System calls, scheduling, and error handling required to execute your equations on a configured interval, outputting the results to other PI Tags. Each equation library contains one or more equations (outputs) and can communicate with tags on multiple PI Servers. Our Equation Scheduler allows you to configure, start, stop and monitor your equations. Once started, you can easily view the details of running equations (inputs, outputs, errors) with EDICTvb.Net’s built-in Library Snapshot utility.

We allow those with process knowledge to create robust calculations based on real-time and historical process data. We provide the framework for data access, scheduling, and error handling, and give you the diagnostic tools to monitor and debug the performance and results of your calculations. If you need to expand beyond the delivered features, you can take advantage of the entire Microsoft .Net framework. With EXELE’s calculation products, your calculation development time will be drastically reduced. Calculations will be easy to support, transportable, and you can be assured that the product will advance with technology. The overall cost of your calculation project will be reduced because you have offloaded the calculation framework to a company with expertise in process calculation software. With your process knowledge, you can create robust calculations based on real-time and historical process data. Generate engineering, performance, economic, environmental, regulatory compliance, or other calculated results from process inputs.
