Functions not working in installed module

Alyssa Wells

I moved a function to an installed module so it can be accessed by all tasks, and it appears to work correctly, but it always returns a value of FALSE even when it should be TRUE.

Are there any known issues of an installed function behaving this way?

This should not be the case...

What Robotware version are you working on? RW5 or 4 (or older)

I use "Shared" setting in controller/automatic loading of Modules to achieve the access from all tasks...

I'm using the current release, 5.15.02.

It is a module set to "shared" so that it is installed as a shared module, and any task CAN access it, but the function never returns true.

Ok, what does the function do - may you upload the code?

Alyssa Wells

It's not an issue with the code itself. The function works if it's not installed.

FUNC bool Function(bool inOK)

VAR bool bOK;

bOK := FALSE;

IF inOK = TRUE THEN

bOK := TRUE;

ELSE

bOK := FALSE;

ENDIF

RETURN bOK;

ENDFUNC

I tried your code and it worked as expected... see attached pack&go including background task and T_Rob1 executing the function call and logging it to the operator output...

 

result:

 

 

 

Please check again, and maybe you need to do a P-Start to reload the correct module into the controller, in case you started with a different one...

And another topic: I only set "Shared" to YES, it's not allowed to set Installed to "YES" too - just in case....
