OK, got it. Here it is for others who might be struggling like I am.

<all_statements>
<if fire_on="logic" minimum_delta_vote_time="100" id="Root Function #">
<boolean_operation type="greater than">
<parameter1>
<analogue id="SC1" time="0"></analogue>
</parameter1>
<parameter2>
<number>4</number>
</parameter2>
</boolean_operation>
<then>
<do function="Trigger Output" functionTargetID="D0" vote_opinion="On" vote_priority="High"></do>
</then>
<anti-then>
<do function="Trigger Output" functionTargetID="D0" vote_opinion="Off" vote_priority="High"></do>
</anti-then>
</if>

</all_statements>

I can't seem to figure out how to get the anti-then part. Do you do another <if>, </if> section but use "not"?

<if fire_on="logic" minimum_delta_vote_time="100" id="Root Function #">
<boolean_operation type="not">
<parameter1>
<boolean_operation type="greater than">

</boolean_operation>
<then>
<do function="Trigger Output" functionTargetID="D0" vote_opinion="off" vote_priority="High"></do>
</then>
</if>

To do antithen, the icon right beside then is what you want. You can do it with another if statement, but it takes more code and makes things harder to debug later.

I figured out how to control an output using an EE-SX1235A-P2 Photomicosensor. But I still haven't got an answer as to whether or not the FB and software will be able to do what I need. Am I barking up the wrong tree?

You're not, we're just not sure what your question is, specifically?

I was referring to the senerio and questions in #1.

hmm, okay. that's still a little vague to me, but the answer is that yes, absolutely it can be done, it's just a tremendous amount of logic and if statements.

If I understand it correctly some of the functions are outside of the main program (like Celcius to Fahrenheit). I see that they are in xml. Can functions be written in another program (say VB) to return a value to a variable to xml?
Does xml have things like being able to "Call" a subroutine? Or is that what the functions are for?
I can write the code I need in a program called WinBatch but don't know how to make it communicate with the FB.

In MDX, a function is an external xml file. Its structure is identical to a logic section, but if you have something you are doing over and over, it is probably easier to have 1 function that is called lots of times from individual logic sections than to have each logic section contain the same root code.

XML itself is just a universally understood data formatting standard. It is just text. Everything in the xml file is parsed by MDX into functional objects.

Calling a subroutine is when a logic section calls a function. A function can call another function and so on.

If you write code in a different program, then you need to use the COM object to pass things back and forth. That means making a whole new program that will communicate with MDX through a shared memory object.

Are the functional objects parsed by MDX defined within MDX or are they (can they be)defined (created?) by the xml code? I guess things like < or > have to have been predefined in MDX.
Is it possible to loop an If/Then a set number of times before going to the next one?
Is it possible to get a list of the possible functional objects written into MDX or are they all avaliable in the configurator?
I'm a little unclear on the timers. I think I read that there are 4 and the If statements could use any of them. If some of the If statements use different timer settings how does that work? I envision that the first time the logic section is run it just flows down to the end and starts again but I get confused when the timers are different. (I'm so confused I'm having trouble describing it)

Also I figured out how to control a output using an SX1235A-P2 photomicrosensor. Would you like me to write a little "How To" with the info I found including the resistor values I used?
Oh Well ... it's very late. Cheers
