How to close ports of an object when a condition is true on another object?

Hi All,

I am working with fluid objects. In my model I am trying to close one of the output ports of a reservoir (Machine 1). When one of the tanks is full(Machine 2).


I know I can use closeop() method in Machine 2 when it becomes full.

But my problem is when I do that it gives me an error saying unknown Variable Machine 1.

I have attached the code below. Any advice will be much appreciated.

treenode current = ownerobject(c);
int mode = parval(1); // 1 = rising, 2 = falling
#define rising 1
#define falling 2
#define either mode
{ //************* PickOption Start *************\\
/**Open or Close Ports*/
/** \nFluid Mode: */
int curmode = /**/rising/**list:rising~falling~either*/;
/** \nObject: */
treenode involved = /**/current/**/;
if (mode == curmode)
{
/** \nAction: */ /**/closeinput(involved)/**closing reservoir port*/;
closeop(Machine1, 1); /**closing output port at Machine 1*/
}
/**\n\n*/
return 1;
} //******* PickOption End *******\\

You must first set up the treenode variable Machine1. The usual options are:

1. A global variable called Machine1.
2. A local treenode variable referring to the object through:
   • port connection : eg. outobject(current,1) or centerobject(current,3)
   • model path : eg. node("/Machine1",model()) or node("/container/Machine1",model());
   • relative path : eg. node("../Machine1",current);

Thanks Jason appreciate the help.

I was able to use inObject(current,1) method. As it Machine1 was the predecessor to the object I was calling that trigger.
