Tips and Tricks for Programming Wonderware SCADA System Software
Blog Post by Quincy Washington
Patti Engineering works with the world’s leading suppliers of robust and powerful industrial automation SCADA software platforms, including Siemens SIMATIC WinCC, Mitsubishi Electric’s MC Works64, InduSoft Web Studio, ICONICS GENESIS64 and Wonderware by Schneider Electric. In this blog post, we explore tips and tricks for working with Wonderware.
Wonderware is a SCADA solution that is being used by many different industries, some of which include infrastructure, oil/gas, chemical and more. The Wonderware platform can easily interface PLCs with HMIs across different platforms and has intuitive and creative graphics used in the software.
Tip 1 – Use the Wizard
Wonderware provides tools already embedded with code which makes creativity more accessible. Figure 1 presents a variety of wizards which are available in the system. These are preprogrammed buttons which only need a tag and all the other work is done.
Tip 2 – Creating Symbols
Another useful tool is the “Symbol Factory,” see Figure 2. With over 60 different equipment categories and hundreds of different shapes/styles, this a unique and useful feature.
Wonderware also features many different communication protocols and user-friendly database interfacing, including SQL, DDE, and SuiteLink. Additional packages are created every few years.
When creating symbols without using the wizard, a properties window pops up as seen in Figure 3. There are several different tabs which give you control over several different categories, for example, if I’m using a discrete fill color. I can also tie a PLC bit to the tag so that if the tag is set to zero it will be one color, and if the tag is set to one it will change to a different color. Symbols can also be changed from within the wizard, but some work is involved in doing so.
Tip 3 – Use the Query for Alarm Systems
Wonderware has its own query for alarm systems and detailed security access parameters, as seen in Figure 4. This can be very beneficial for those less experienced with programming. The alarms can also be grouped by different names, which is helpful for troubleshooting PLCs which are controlling multiple stations. Manuals give detailed explanations and examples of utilizing these features.
Tip 4 – Using Scripts
Key scripts are useful for associating hidden screens other users may not have access to, or quick shortcuts to screens in case an issue arises.
Overall, Wonderware is a very useful SCADA solution for industry. It is a great way to learn how to interface HMIs with PLCs and understand how data is transferred across different platforms.
