Designing large-tag-count SCADA systems
The magazine Control Engineering ran their monthly Information Control email today which included a tutorial from MultiTrode and Parasyn:

They describe the tutorial:
SCADA systems aren’t scalable out of the box; you have to plan with the final footprint in mind,” says Tony Poole, managing director of Parasyn, a system integrator specializing in water/waste water applications. Steve Carson is with MultiTrode, a manufacturer of MultiSmart pump station manager units, which are replacement devices for pump controllers or PLCs/RTUs for lift stations. The devices add more monitoring and control capability to SCADA systems, and can also add 400 to 500 tags (data points) per site. In this tutorial, Carson and Poole provide best-practice advice for designing large tag count SCADA systems so they are manageable.”
Control Engineering have a number of email newsletters that you can subscribe to. There’s plenty of good quality articles that make it worth the free subscription. Just visit http://www.controleng.com and you will see the Newsletters menu item on their site.
There’s a story behind how we came to write that article together, a subject for another day.
We find the subject of large tag count systems very interesting – we’ve run into it a number of times and in different elements of the SCADA solution. Parasyn’s approach made a lot of sense when they explained it to us and we certainly learnt from their experience.
“SCADA systems aren’t scalable out of the box; you have to plan with the final footprint in mind,” says Tony Poole, managing director of Parasyn.
Have a read of the article. It will be in the print edition of Control Engineering in April.
