DSC runtime engine problems

Question

Hi, 
I recently started a project which involves DSC runtime engine. This being my first contact with runtime engines, i obviously ran into some problems. Hope someone can shed some light. Here goes: I developed a project on my work laptop on which I have LV / DSC 8.6 installed. The project is then built into an EXE application and then run on a desktop computer with DSC runtime engine.The desktop computer receives data from a PLC through an OPC server (which is not NI OPC server). At first, I imported a csv file containing the list of variables in my project with the correct path of the OPC server from the desktop. When I ran the EXE application on the desktop, I got an error (PSP Led was red) saying that the variables could not be read / written. This was because the variables were not declared in the Distributed System Manager. And so my first question is this: is there a way to import my list of variables from a csv file or something similar, and if so, how can i achieve this? Because so far, all I was able to do was to manually enter only one variable at a time in the Distributed System Manager, and after about 50 of them I decided I would really hate to enter almost 800... 
 My next question regards the Citadel Database. As I told you before, I entered a few variables in the system manager and played with them for a brief amount of time. I set them T / F, I got the correct readings from OPC server, my PLC leds light up, the works. Now I wanted to see my actions in the Citadel DB, but when i ran MAX, there was no Citadel DB, only Default DB, and I could not find any of those variables which I entered and chaged states. Is there a problem with the Citadel DB not showing up? Am I not declaring correctly the variables in the System Manager? (i followed the help directions to the letter). Anyone has an idea as to why I cannot see the varaibles in my DB?
And now for a final problem.. In the LV front panel, i have some boolean buttons which are set to switch when pressed Mechanical Action. When I have the PLC connected sometimes when I press a button, it remains stuck on the TRUE state, thus screwing up my logic scheme (e.g. for a feed mill conveyor motor I have two buttons - start, stop. If i sometimes press the start button and it gets stuck, i can no longer SHUT DOWN that conveyor, which is really a big problem. I found a so-called 'fix' - right click on the stuck button and select Reinitialize to default value, but I was looking for an answer to understand this problem, not a silly little fix).
Hope I have been clear enough and you have not got tired of reading so much,
Cheers,
Sabin

 Hi Andrew and thanks for the reply!
 I don't think I deployed the library file, because I didn't know exactly how to do it. In the Source Files Property Page on Build Specifications I only selected VIs. I never selected lvlib files, so this may be the case. On the Source File Settings I saw that .lvlib files had the property Include if referenced and I thought that was the property which deployed the library. I will change the build specifications at once and keep you updated, but it could take 1 or 2 more days, because the computer with DSC runtime is in another city, and I have to get there first maybe tomorrow.
 I have several buttons set on Mechanical Action Switch Until Released. They are all Shared Variables which are connected through OPC server to memory locations in the PLC CPU. In my LV Block Diagram, they are NOT connected to anything. They are just located in a While Loop, to get their state. The preffered action is that when I press a button on my Front Panel, I get to change a memory location in my PLC and then something happens in Ladder Logic. So, the boolean values are just there, in my Block Diagram, alone and not connected to anything. Do you have an idea as to why I get that kind of behaviour (I mean the buttons get stuck on True state)?
 And finally, someone told me that the Citadel 5 might be missing because of incorrect option checking at install. However, I remeber that on the desktop, I installed the DSC runtime engine FULL INSTALL, I mean I checked each and every tick box, everything, examples and the like. One thing I was told was to insert the install CD once again and perform a re-install. I will of course try this, but let's not consider this for a second. Do you have another idea as to why the Citadel DB wouldn't show up?
 And no, in the EXE Build Specifications, I did not check the option Enable Enhanced DSC Run-Time support. What does it do? Could you please elaborate?
 Looking forward to your answer,
Sabin
