Andover Controls Continuum Web Client

So, I have a new job (as of one month ago) at RLSM (Robert Loyd Sheet Metal). We've been doing HVAC installations for over 25 years. Recently, a lot of our money comes from doing controls. That's what I go hired as - an Assistant Control Engineer. Basically I do graphics for workstations, and technical drawings of the control design.

Andover Controls is our favorite <3 brand of controller. It is easy to work with, easy to make graphics for, and has the least bugs and difficulties. Probably because it is made by the supplier of most of our parts, Schnider Electric. Continuum is the name of the database/workstation software.

Today, I was learning about the Continuum web client (cleverly named WebClient). It was an interesting thing. WebClient is a program that runs on the server with Continuum, and provides web access to the Continuum Graphics pages.

Unfortunately, all that was necessary background for the one short little statement I have. That is, "WebClient provides ASPX pages that open up Java applets running Continuum graphics!" A beautiful marriage of Microsoft and Sun. Oh, I'm such a newb. I just got excited because that's basically exactly what I learned in school: C#/ASPX, and Java. Probably someone else did too.

Anyways, there is hope. I may still program professionally yet. My little detour into assistant engineering is quite educational. Although it is not necessarily my prefered or first choice of curriculum, I am grateful to learn what I can. And, it is all quite interesting and valuable information I am learning, none the less. Like what points a typical MAU has, and why.

(A Make-up Air Unit is installed to provide air to make up for the air lost due to an exhaust fan. Typically it will have a current sensor to detect if the exhaust fan is on or off, but the exhaust fan does not need a command output from the controller. It is just manually controlled. Why we don't just wire the MAU fan straight to the exhaust fan switch? I didn't ask, so I don't know. We could do that to be cheap, and it would save us on an output command, and we could leave the current sensor to both fans just to monitor them, but . . . that's just not how we do it.)
