Why I cant update a message on CANoe via a Panel?

Question

Im trying to update in "real time" the value of a message using a panel. However once the simulation starts , the panels shows this icon with a tooltip that indicates that "my signal value was not sent yet". Any idea why this happens ? The combo box is attached directly to a signal in the database and the related node is on the network simulation.

Note: I'm running this on CANoe v11

Answer 1

The likely reason for this is, 'you are not using any interaction layer (IL)'.
When you change the value of a signal in the Panel, the signal has to be sent by something in the Simulation Setup. This "something" is the interaction layer.
Once you add the IL, changing the signal values in the Panel will change the value of that signal in the "signal server" of IL. So, whenever the message is sent by the IL after the change in the panel, the updated value will be sent.

Last answer is correct, OR the signal has in dbc attribute

GenSigSwitchedByIgnition = 'Yes'

and the ‘SW-KL15’ is off. (The ‘SW-KL15’ setting of the signal attribute GenSigFuncType allows assigning a special behaviour to a signal depending on the value of EnvKlemme15.)
