What Happens in the Shadows
Sometimes you come across situations that just don’t happen very often. It’s hard to justify the research and development time to invest in instruments or programming concepts that aren’t all that likely to come up again. Here are some of those I’ve come across:
Dynamic Density Level via Pressure
Setting up a bit of automation for a vessel whose level is measured with a pressure sensor and whose media tends to vary in density.
Fuji Frenic-Eco Inverter Config

TAS Explains First Out
This was an explanation for a customer to help them understand how the first out logic was triggered in their alarm AOI. While the code is specific to that AOI, the overall concept can apply to many situations.
