Dear All, I am very new in TRNSYS. What I am planning to do is I want to couple between Simulink and TRNSYS . As I know there is the way to couple mfile and TRNSYS. but i didnt found yet how to couple .mdl file and trnsys. Initially, I try to create on_off controller by modifying example mfile and type155 and I wanted to change original on_off in trnsys SDHW however have error .. " the m file has flaged an error . Return value for mfileErrorcode :101 the error occurde at info(7)=0,info(13)=0." ..and I dont know how to solve it... I am glad if somebody have idea to help me to solve the problem.. I am sending the m-file and project-file in attachment. Thanks a lot in advance, Best regards, Hanani
% On_Off Controller
% ----------------------------------------------------------------------------------------------------------------------
%
% Example M-file called by TRNSYS Type 155
%
% Data passed from / to TRNSYS
% ----------------------------
%
% trnTime (1x1) : simulation time
% trnInfo (15x1) : TRNSYS info array
% trnInputs (nIx1) : TRNSYS inputs
% trnStartTime (1x1) : TRNSYS Simulation Start time
% trnStopTime (1x1) : TRNSYS Simulation Stop time
% trnTimeStep (1x1) : TRNSYS Simulation time step
% mFileErrorCode (1x1) : Error code for this m-file. It is set to 1 by TRNSYS and the m-file should set it to 0 at the
% end to indicate that the call was successful. Any non-zero value will stop the simulation
% trnOutputs (nOx1) : TRNSYS outputs
%
%
% Notes:
% ------
%
% You can use the values of trnInfo(7), trnInfo(8) and trnInfo(13) to identify the call (e.g. first iteration, etc.)
% Real-time controllers (callingMode = 10) will only be called once per time step with trnInfo(13) = 1 (after convergence)
%
% The number of inputs is given by trnInfo(3)
% The number of expected outputs is given by trnInfo(6)
% WARNING: if multiple units of Type 155 are used, the variables passed from/to TRNSYS will be sized according to
% the maximum required by all units. You should cope with that by only using the part of the arrays that is
% really used by the current m-File. Example: use "nI = trnInfo(3); myInputs = trnInputs(1:nI);"
% rather than "MyInputs = trnInputs;"
% Please also note that all m-files share the same workspace in Matlab (they are "scripts", not "functions") so
% variables like trnInfo, trnTime, etc. will be overwritten at each call.
%
% ----------------------------------------------------------------------------------------------------------------------
% This example implements a very simple component that returns the double of each input as the corresponding output.
% The component is iterative (should be called at each TRNSYS call).
