Energyplus co-simulation toolbox - ExternalIn​terface:Ac​tuator

I am a user of "Energyplus Co-simulation Toolbox" downloaded from "https://github.com/dostaji4/EnergyPlus-co-simulation-toolbox".

I used "ExternalInterface:Schedule" in the "ExternalInterface" options to get the desired result.

But when I use "ExternalInterface:Actuator" among the "ExternalInterface" options, the following error occurs.

Java exception occurred:

java.net.SocketTimeoutException: Accept timed out

at java.net.DualStackPlainSocketImpl.waitForNewConnection(Native Method)

at java.net.DualStackPlainSocketImpl.socketAccept(DualStackPlainSocketImpl.java:135)

at java.net.AbstractPlainSocketImpl.accept(AbstractPlainSocketImpl.java:409)

at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:199)

at java.net.ServerSocket.implAccept(ServerSocket.java:545)

at java.net.ServerSocket.accept(ServerSocket.java:513)

I know that the ExternalInterface:Actuator option only allows limited variables.

I ran the simulation while recognizing the content of it, but I keep failing.

My code is follow.

clc

clear all

ep = mlep;

workDir = 'C:\Users\USER0001\Desktop\#BESRG\2020\논문\EMSTEST\ANN_all_In_One\test';

ep.idfFile = 'EMSWindowShadeControl';

ep.epwFile = 'KOR_Inchon.471120_IWEC';

BG_Simul_DayDay=24; % hour

ep.initialize;

inputs = ep.inputTable;

outputs = ep.outputTable;

timestep = ep.timestep; %

endTime = 4*24*60*60; %[s]

outputSigName(1,1)={'iradiance'};

outputSigName(2,1)={'Angle'};

logTable = table('Size',[0, 1 + ep.nOut],...

'VariableTypes',repmat({'double'},1,1 + ep.nOut),...

'VariableNames',[{'Time'}; outputSigName]);

t = 0;

iLog = 1;

while t < endTime

u = 1; % Control Status

y = ep.step(u);

t = ep.time; %[s]

logTable(iLog, :) = num2cell([t y']);

iLog = iLog + 1;

end

ep.stop;

or, can i get a very simple example code using ExternalInterface:Actuator?

Hello,

if you can send me an example IDF file with ExternalInterface:Actuator I'll have a look at it. I recall fixing a bug in the ExternalInterface:Actuator reading .. But I could not verify with EnergyPlus in the loop.

Send me please the IDF at [e-mail] and I'll try to fix it.

Sorry for not responding earlier, but I have to manually from time to time search the Mathworks site for the keywords to see the questions.

All the best, Jiri

Thank you so much for your answer.

But I hvae already solved the problem. I don't know how it worked. Just changing a lot of options and trying several times solved the problem.

I'll remember your email. If you're okay, is it okay to ask questions by email occasionally?

Again, I really tanks your help.

Best wishes, Jeon.

[Jiri Dostal]

Yes, contact me, if you need anything. I'll try my best ;). Jiri

Hello,

I'm also a user of MLEP toolbox.

I used "ExternalInterface:Schedule" in the "ExternalInterface" options to get the desired result.

But when I try to use "ExternalInterface:Actuator" or "ExternalInterface:Variable", the bellow errors accurs

''Error using mlep/loadIdf (line 772)

Subscripting into a table using one subscript (as in

t(i)) or three or more subscripts (as in t(i,j,k)) is

not supported. Always specify a row subscript and a

variable subscript, as in t(rows,vars).

@Byung - Gi Jeon I saw that you used one of these options of External Interface whith succes; any ideas to fix these errors? Or can you please share with me one of your simply code and idf file?

@Jiri Dostal Can you please help me to fix it?

Thank in advance for your reply
