WARN: Missing input parameter value for Activity

Postby mohammad.mozumdar@aero.org » Tue Aug 21, 2018 5:39 pm

I am trying to simulate a system in which I will use "Signal" to communicate between different blocks. The signal will have "attributes" which will carry values associated with that signal. Here is the BDD

Here is the signal tick with TWO attributes insider "Sender" block

Here is the activity diagram that process the tick signal

Now, I get following output which looks strange to me..

So, it seems to me that "tick" signal generated with null values? I have also attached the model. It would be great to know how to solve it. Thanks!

Hello,
The issue has been solved in Simulation 19.0 as attached image. Please consider upgrading Simulation with the latest service pack or version 19.0.

Hi Chairat,
Thanks for your response. I have updated to 19, and surprised to see that I have still the same problem. To simplify, I have removed ON signal from the model. Now, it sends at first TICK signal with two attributes. I get TICK signal with "null" attributes values.

How do I "consume" a signal? Could you please point me the reference manual? I have attached my model here:

Thanks!
