Dear Eleni, <br>
<br>
What is the error message given by TRNSYS when you link Type 62 with
Type 56? <br>
<br>
Are you sure that the EXCEL File path define in Type62 "Control Card"
is all right? Are you sure that your EXCEL File is correctly defined ?<br>
<br>
Concerning your profile, you will have to use several Type to describe
your profile like you want. First, define each of your profile in
columns in your EXCEL File. Then use equation windows or Type 515
("Application Library( TESS)" --> "Heating And Cooling season") to
define Summer and Winter, and Type 516 (""Application Library (TESS)"
--> "WeekDays Saturdays" --> "Type 516") to define weekdays and
week end hourly schedules . Then combine the EXCEL File outputs with
Type 516 and Type 515 outputs in an equation window to build the
one-year profile you want.<br>
<br>
You can see the attach file as an example.<br>
<br>
Best regards, Adrien<br>

<pre wrap="">About my problem now,
I was not probably very clear with my first email. I am doing what you suggest, as I have followed the example before hand. The problem is that when I link type 62 with type 56 TRNSYS does not run, as I get an error. In addition, the 6 typical days of the year represent winter shoulder season and summer weekdays and weekends. So I have to combine these to represent a year. Do you have anything to suggest?
Would you mind if I post this reply including the Forum emailing list, as it might be able to help others in the future as well?
Best Regards
ELeni

<pre wrap=""><!---->Dear Eleni,
First, you'd better have a look to the example "Excel Schedule.tpf"
(exact path : \Trnsys16\Examples\Calling Excel) to better understand how
Type 62 works. You will see that EXCEL file datas are only defined on 24
hours, and they are repeated every 24 hours (In that example, the run
last 168 hours, you can also change the "Simulation Stop Time" in the
Control Card to be sure that the data are repeated). So if you just have
6 typical profiles, just define them in your EXCEL file, and they will
be automaticaly repeated every 6 days.
Then, you just have to connect Type62 outputs to Type 56 inputs. No
matter that Type 62 results are dimensionless.
Be careful to define a 5 min "Simulation Time Step" in your control card.
If you have a problem, don't hesitate to send me your project.
To finish, I am interesting in you internal heat load profile EXCEL
file, so it will be grateful if you'll be able to send me that file.
Best regards,
Adrien

<pre wrap="">Dear users,
I am using electrical profiles to simulate the internal gains of my buildings. These are given in
spreadsheets (5 min intervals and the unit is Watts). I use type 62 to call the excel and have the
files read by TRNSYS (I convert the data to kJ/hr). I get a correct result when I link this with a
plotter (as in the example). I have also assigned an INPUT for the zones' internal gains in type 56.
My problem is how to connect these two in the simulation studio (the results of type 62 are
dimensionless). In addition, I have 6 typical days of the year (6 daily profiles) which will fully
represent a whole year. Can anyone suggest a way to call the right profile in each repetition of
macros in excel? (or maybe another way to do that?).
I am a beginner and I am struggling with these problems, so any help would be appreciated... Thank
you in advance :)
