How to refer to an inactive taskexecuter by the red-line connected network node

For example, several TEs are running on a network which is constructed by several NNs. At a certain time, for instants, I would like to know who is inactive at NN3. Is there a direct way to refer to the TE by its red-line connected NN? I do not want to use On Arrival and On Continue triggers in NN.

Thanks a lot!

One way would be to check the TEs to see which TEs are idle and determine which are red-line connected to NN3 using gettenetnode().

Hi Danny,

Thanks for your reply. Actually, I just want to understand data reference mechanism between DefaultNetworkNavigator and Network Node.


Image above show NN2 has two inactive TEs. The numbers I marked with red circle shows the rank of the TE in DefaultNetworkNavigator's traveler member list which is marked in the image below.


The problem is I do not know how to refer to the inactive TE by the information in NN.

Thanks!

Hello Hao,

the node number can you get with the command getnodenum(node in the tree) - I have selected this node as "Designiate this node (so) from the context menu > edit"
This number is a reference to the node described as the string ("/Operator4>variables/navigator/1")
To Build a pointer use the command tonode(from a number)
Now you have the reference to a node in the attribute tree of the operator4
To get the reference to the root object use the command ownerobject( node obj).
To show that this works you can use

getname(ownerobject(tonode(getnodenum(so()))));

Hi Joerg,

Thanks for your reply. In my previous reply, I showed two images. In the first image, I make a red circle for the rank number. Is there a way to write some code in order to get the rank number? With this number, I can find the TE.

Thanks,
Hao

Hello Hao,

instead of "gename(ownerobject(....))" use "getrank(up(...))".

I have designated one of your circled nodes as (so) and the following code row gives you the desired rank:

 
getrank(up(tonode(getnodenum(so()))))

Hi Joerg,

Thank you very much! Problem solved!
