how tp get the number of the input port of the incoming item

Is there a function to get the number of the port through which the flowitem has entered an object?

I have 42 input ports connected to an object and I am modifying the tasksequence of the Task Executer as Flowitem which depends on the port the flowitem has come from.

It can be either in a label or only a function to be inserted in the tasksequence code.

Actually what I really need is to get the networknode to which the upstream object (which has just passed the flowitem) is connected to.

So I was thinking of using

getnetnode(inobject(current, * port* ),1);

but then I don't know how it works when I have 42 ports and it has to be the port through which the object has just entered the model.

Any ideas?

Carolina,

in an OnEntry trigger you have access to the port number a flowitem has entered an object through simply using the variable "port".
The command getnetnode() does refer to the blue connection line, not the inport number. Look that up in the command help please. To make that work in your case, you would need to have 42 network nodes connected to your object corresponding to the 42 inport connections.

If you only need a reference to the network node an item came through, just add a label to the item and on all network nodes' OnContinue triggers set the reference to the network node as a value in that label.

Maybe you want to post your model to see exactly, what you are trying to do? That would reduce the effort over here to help you a lot.

Thank you Ralf!

What you said will work for me. I have 42 networknodes.

What I just tried is to set label using at the on exit trigger of my "upstream" object opipno(current,1) and use that number to get the networknode which is connected to both upstream and downstream object.

Maybe it is simpler in the way you mentioned: using the networknode as a value in a label. I will try this way and see what suits me best!

Thank you very much! I am a very beginner and I am having difficulties in finding what I actually need on the command reference.
