There is hardly a home or business that does not hve some kind of a network in place or wants one or has one that needs some tuning, repair or other service. But the problem is that in this day an age there are too many network "experts" and "gurus" that have mystified the whole process and for any network service at all, you have to hire an expert and have to pay for an evaluation, estimation, diagnostics and a whole lot of other formalites before you can get anything done at all!

At CITS we make everything very simple and straight forward for you. Simply call me directly and I will fly out there and do whatever you need done at your site. All you will be paying is the cost of travel, the air fare, hotel and my per diem and then a simple labor rate of $193.20 per hour, that's it. And of course the cost of materials. Who does that nowadays? Please ask aound and find out. Obviusly I am not looking to get rich here at this point. Just to keep busy and do YOU some good! That's all. Please don't fall for that high sounding network lingo and trust my experience. I solve problems just standing there!!

Remember, the good Microsoft and other great vendors may have invented and put the network systems in place in the first place and the network gururs are great people but they will make you go thrugh a very formal and stiff process. Whereas I will get it working informally and completely before they will figure out what to do even! And I will figure out and setup the network design without even using a piece of paper and pen! Well, may be a pen and a notebook. But I will give you a write up after all is setup. Don't worry there will be some documentation!

My number is (651)442-9044 and is almost alway ON. I am looking for a PROBLEM to fix!

And I forgot to say, I work on networks Small or Lage, at home or abroad. Nothing is too small or too big. I have not said "NO" in my life yet!

Thank you.

CEXCEL1002      Excel RACL Programming I


Class Type            Programming


System                   Excel/Excel Microcentral


Duration                4.5 Days


Class Audience    Programmers of down-line Excel processors and/or maintenance personnel for the Excel Controllers in Excel Microcentral or Distributed Excel HVAC Systems          


Offered At             Customer site or St Paul


# of Students        Minimum 5, Maximum 8


Cost                        $1990 per person at site, $1290 per person St Paul


Brief                      The course starts with a brief introduction to an Excel/Excel Microcentral System using a simplified block diagram.  The function and intent of a DDC program in an Excel panel is then elaborated on and the difference between an Energy Management Program and a DDC program is pointed out.  The course then goes  into a study of the elements of the Honeywell Programming Language RACL (Recursive Algorithmic Control Language) the language in which Excel DDC programs are written.  Each set of Operators of the language is introduced with an example program segments which are actually tested on line.  The course also discusses some of the powerful DDC submodules provided on cassette.  These submodules convert the RACL language into a truly structured programming language ideally suited for HVAC control.  Again some of the submodules are actually used in program segments and tested on line.  The technical functions of flowcharting, writing and testing of programs are performed repeatedly to enhance learning and internalizing of a certain definitive analytical thought-pattern.


                                Written exercises are used to reinforce the learning process.


 Objectives            Upon completion of the course the student will be able to:


·         Identify the Point and Program of an Excel Controller database
