  • DeltaV Blog: What is the Best PID Execution Time?

    Gregory K McMillan
    An execution time that is too slow can degrade control loop performance. An execution time too fast can unnecessarily increase the loading in the distributed control system (DCS) or programmable logic controller (PLC). Less recognized is an excessively fast module execution time can cause the module to run out of free time, decrease the signal to noise ratio, and increase valve packing wear. read more Read the full text…

  • DeltaV Blog: Control Using Wireless Devices – Part 1

    Terry Blevins
    Work on the WirelessHART specification began over seven years ago. Since that time the WirelessHART specification has been published by the HART Communications Foundation.

  • DeltaV Blog: We Interrupt This Blog Post to Bring You This Important Blog Post

    Bruce Greenwald
    I've been back in Texas since October, getting acclimated to all things uniquely Texan, like great BBQ and killer margaritas. I’m also working on my Texas-speak (y’all). While I’m back in the live music capital of the world, I’m still not sure I’m ready to go out two-stepping, but I knew it was time to start blogging again. I was in the middle of putting together by my first blog post in over 4 months (the topic was…

  • DeltaV Blog: Monitoring Turbine and Compressor Operation

    Terry Blevins
    In January I posted a series of four (4) blogs that addressed the implement of an on-line compressor efficiency calculation. The example for this series was a compressor for a refrigeration system that used R134a refrigerant. If you have a similar compressor application in your plant then the information provided in these blogs may act … Continue reading » Read the full text.

  • DeltaV Blog: Compressor Surge and Stall Detection and Prevention

    Gregory K McMillan
    A compressor going into stall is like jumping off a cliff with a bungee cord. If the bungee cord has no losses to dampen the oscillation, we have something akin to surge. A 0.5% drop in efficiency can occur for each surge cycle. Several surge cycles can occur due to delays and lags in high … Continue reading » Read the full text.
