As an applications engineer, sometimes known as OptoMary on our OptoForums, perhaps I shouldn’t have favorite customers. They’re all my favorites!

Sure, our products and people have helped build flashy Vegas shows, huge amusement parks, and various NASA endeavors that we may or may not be allowed to discuss in detail. We also have the less flashy water/wastewater installations and beloved "dam customers" that can be pretty Coulee, too.

In these Adventures of an Applications Engineer posts I'll share some of my favorite favorites.

OptoForum member tohox recently posted a question about using PID control loops on a SNAP-PAC-R1 rack-mounted controller.

The issue? A really long dead loop time. 

"The time delta between the moment the strategy opens a given loop's valve [and] starts the pump+furnace and the moment a temperature increase is measured can sometimes be on the order of an hour," tohox notes.

OptoNews: Case study: M-Bus building systems data

Posted by Jean Femia on Nov 18, 2015 5:26:07 PM

How do you get a variety of building systems and machinery to communicate with a central system controller, when they use different protocols? 

Swedish system integrator Processcomponent AB had to solve this problem when they installed an energy monitoring system in a large apartment building in Gothenburg.
