<p>Salma,</p>
<p> The most common cause of this problem is that the Type155.dll
file located in your .\Trnsys18\Exe\ directory is not the one for
the version of Matlab that you are using. Look in the
..\Trnsys18\Exe\DLLs\ directory and you'll find various *.zip
files containing versions of Type155.dll for different versions of
Matlab. If you find your Matlab version then replace the existing
Type155.dll with the one from the *.zip file. <br>
</p>
<p> There are a number of other possible causes of this error. It is
hard to diagnose because a lot of times it has to do with the
configuration of Matlab and TRNSYS and your computer. Here is the
knowledge base that we have collected:</p>
<p>• Avoid the use of the Matlab “clear all” statement. This
statement has been found to delete all of the data that is being
passed from TRNSYS to Matlab.<br>
• <b>Make sure that neither TRNSYS nor Matlab is installed in
the .\Program Files\ directory.</b><br>
• <b>Make sure that both your user account and the SYSTEM user
(a built-in Windows user account) have full administrative
privileges.</b> <br>
• <b>The Type155.dll in your ..\TrnsysXX\Exe directory must
match the version of Matlab that you are using. DLLs for various
Matlab releases are located in the ..\TrnsysXX\Exe\DLLs\
directory. If you find your version of Matlab there, extract the
Type155.dll and place it in ..\TrnsysXX\Exe, replacing the file
that is already in that location. If you do not see your version
of Matlab in the ..\TrnsysXX\Exe\DLLs\ directory please contact
your distributor; they can provide you with an appropriate
version of the file.</b><br>
• Add the path to libeng.dll, which is normally located in
C:\Matlab\bin\win64, to your windows search path (assuming you
installed in C:\Matlab, otherwise adapt)<br>
• To do this, in Control Panel, System, Advanced System
Settings, Environment variables, edit the Path variable (we
recommend that you edit the one in System Variables rather than
User Variables). Add “C:\Matlab\bin\win64;” (without the quotes
but with the trailing semicolon) at the beginning of the search
path. You will notice that Matlab has added other subdirectories
of C:\Matlab to the path but not that one (and you thought TRNSYS
was bad…).<br>
• If you also install the 32-bit version of Matlab you should
make sure that the win64 directory appears before all other
references to Matlab in the path. NOTE: some users have found that
they need to remove all other references to Matlab in the path,
regardless of their relative placement.<br>
• Note that if you change the path while the TRNSYS Studio is
running you will need to restart the TRNSYS Studio.<br>
• Some users have found it necessary to run the command
'regmatlabserver' in your Matlab command window. This registers
Matlab as comserver.<br>
