DDave reacted to noumenal_world's post in the thread Gain and Bias on PV and STPT on a PID controller [Ovation DCS] with
Like.
Those Gain and Bias fields aren't tuning parameters they're a straight linear scale (percent = EU × Gain + Bias) that maps your PV and... -
DA FIFO or queue of part records still sounds like the right approach here, especially since the spacing between parts isn't fixed. I...

DDave reacted to Jason Hogan's post in the thread Life expectancy of 24VDC power supply continuously being in use in DCS & PLC System with Like.
MTBF is just statistical math, not component wear-out life. In real-world 24/7 DCS panels, top-tier 24VDC supplies usually last 8 to 12...
