Gain block ignored :

I have a Simulink model with a gain block that has a ToWorkspace before and after, yet the ToWorkspace traces are identical even though the gain has been set to 64, any ideas what may be causing this?

Need more information. What are the settings in each "To Workspace" block?
Variable Name
Data limit
Decimation
Save Format
Sample time

The input value to the Gain block is constant zero? Need more info to see the problem.

Without the data type conversion block, the output should still be 64 when the input is boolean true, right?

Hey Guys,
I have an similiar issue.
I have an Signal which is not 0. Then I put an 0 Gain to it... with an parameter which is read from the base workspace.
That value is 0 so I would thing the output of the Signal*0 is 0... but it isn´t it has the value of the signal.
But when I write the 0 directly into the gain hen it works and the output is 0.
The datatype conversion has no effect... .

You are saying that you have a Gain block, its "Gain Value" is a parameter from the base workspace, the value of the parameter is 0, yet, the output of the Gain block is non-zero.
It is strange. I would double check the value of the parameter, the name of the parameter, lower case, upper case, etc.
There is a chance, that there is a parameter with the same name, in the model workspace, its value is non-zero. The variable in the model workspace takes precedent over the base workspace, if their names are the same.

You were right. Somehow I saved a value in my model workspace.
Thank you very much.
Have a nice weekend.
