We have a new Perfect Abstractions Blog located here: http://blog.perfectabstractions.com
Our developers are writing great new blog posts, check it out!

Here is a checklist that can be used to evaluate SCADA frameworks:
A software abstraction is computer code or software that conceptually represents something and provides access to functionality and/or data.
This video shows how to configure and use the News Reader template in Ignition.
The silent video shows how to do it. Sorry for the beeping sound. The steps to do it are listed below the video.
I created a free community based instant messaging chat group for Ignition. You can become a member of the chat group by registering. Send me a quick email (firstname.lastname@example.org) and I will send you an invitation link.
OPC-UA stands for Open Platform Communications Unified Architecture. OPC-UA is a communication standard. It is a set of documents that provide rules and information about how software applications and devices can send and receive different kinds of data between each other.
I recently developed an RSS reader called "News Reader" for Ignition. If you would like to display news or information from a website or blog in an Ignition project, this is for you.
The News Reader is a template that can be added to Ignition windows to display Internet feeds.
This is how to embed an Ignition project as a Java applet in a webpage.
Java does a pretty good job at making applications look the same on Windows and Linux. But the default fonts that Java uses on Linux are not the same fonts used for Windows. This causes a problem for implementing GUI projects on Linux that will be used on Windows. The default font used on Linux can have different dimensions than the fonts used on Windows causing differences in the flow of text and messing up components in windows. Here is an example:
I am very interested in creating a Weather Radar Module for Ignition. The module would provide a new component that provides a map of weather conditions.
Testing and debugging event scripts on components is easy. Open up the Output Console in the Designer and sprinkle your code with print statements to see what is going on.
This approach doesn't work as well with gateway scripts because print statements are not output to the Output Console in the Designer.
A gateway script is any Python script that runs in the Gateway and not in a designer or client. Here are a variety of tools to use for testing and debugging gateway scripts:
