message never received from network node to quay crane

Hi everybody,

I send a mesage from OnArrival of a NetworkNode to a Quay crane which is connected to it as follows:
sendmessage(node("/GantryCrane1", model()),current,8);

then in messagetrigger of the QuayCrane I use the following functions:

pt( getname(msgsendingobject));
or
pt(getname(parnode(1)));
or
msgparam(1)
to print something to console but I get nothing. While it seems that "messagetrigger " is frequently called (because the window scrolbar is moving up and down quickly during the run) but the print command in it is not ran.


SO how to receive that message inside the quay crane to ask the quay crane to let say stay IDLE for certain time until another transporter arrives.

any comment aprpeciated.

Shahin,

It seems strange the error you have reported. Try one of this solutions:

1) Have you checked that node("/GantryCrane1", model()) exists??

2) Have you got the OnMessage Code at the Crane's OnMessage Trigger??

3) Is the Crane connected to the network??

Good luck!

Hello Shahin,

I think you have written in your code:
pt(getname(msgsendingobject()));

and you have left the brackets only here.

Further on have checked if the on arrival-trigger is fired.

Hello Jörg,

Thank you for your comment.
in the tree edit windows there a trigger called "messagetrigger" (I havnt seen OnMessage anywhere) and inside that I leave just a normal simple pt("hello");pr(); but even that does not appear in the output console.
In fact this is a Quay crane not a Gantry --- sorry for my mistake.

the braces i added also did not solve the issue.
regards,

You need to toggle the node as Flexscript and build Flexscript after editing it from the tree.

Also, you aren't going to be able to do what you are trying to do by sending the quay crane a message.

The task sequences in CT are complicated coordinated task sequences created by the CT dll based on the information you specify in the Planners. You do not have direct control over what happens with the objects like you do in regular Flexsim. Flexsim CT trades flexibility for simplicity.
