Block connection including an array
Hello guys,
I have two Blocks, A and B and I want to connect both of them (graphicly) and the data (array) from block A should be transfered to block B.
Here I small example
Code:
block A
extends Modelica.Blocks.Interfaces.MO;
parameter Real a[:] = {5.0, 2.0};
equation
y = a;
end A;
block B
extends Modelica.Blocks.Interfaces.MIMO;
equation
y = u;
end A;
So far so fine, but now comes the connection (graphical) in the connection editor. I connect A with B, now I have to enter the indices, for A.y[index] to B.u[index]. I am not able to use the hole vector of A to connect to B, only 1 scalar of A can be connected to B (input and output of must set to 1).
Code:
equation
connect(A.y[2], B.u[1]) annotation(Line(points = {{-63, 40}, {-10, 40}, {-10, 32}, {-10, 32}}, color = {0, 0, 127}));
I solved this problem with a for loop to connect the hole array A to B
Code:
for i in 1:2 loop
connect(mV_Test1.y[i], pS_Test1.u[i]) annotation(Line(points = {{-63, 40}, {-10, 40}, {-10, 32}, {-10, 32}}, color = {0, 0, 127}));
end for;
The simulation works fine, the result of Block B is y[1]=5 and y[2]=2
BUT now I have no more graphical connection line in the connection Editor between A and B :-(
Some one who can help?
Thank you
Re: Block connection including an array
Hi,
I took your exemple but I rewrote it in anathor way, finally it works well
Code:
block A
extends Modelica.Blocks.Interfaces.MO(nout=2);
parameter Real a[2] = {5.0, 2.0};
equation
for i in 1:2 loop
y[i] = a[i];
end for;
end A;
//
block B
extends Modelica.Blocks.Interfaces.MIMO(nin=2);
extends Modelica.Blocks.Interfaces.MIMO(nout=2);
equation
// for loop to run out our model
for i in 1:2 loop
y[i] = u[i];
end for;
end B;
//
model AB
A a1 annotation(
Placement(visible = true, transformation(origin = {-128, 12}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
B b1 annotation(
Placement(visible = true, transformation(origin = {14, 10}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
for i in 1:2 loop
connect(a1.y[i], b1.u[i]) annotation(
Line(points = {{-116, 12}, {2, 12}, {2, 10}, {2, 10}}, color = {0, 0, 127}, thickness = 0.5));
end for;
end AB;
