Hi Cesar,
I just had a look at your mspec changes. I think it shouldn't be
"getCpuSubfunction" but " cpuSubfunction" ... the code generator takes care of
generating the right access code. For my C templates this code is sometimes
greatly different from what you would expect in Java.
Actually that should be about all that has to be changed.

Hi,
I am trying to perform the migration to add the functionalities for the S7
driver, associated with the subscription handling of alarm and system
events, but I am generating a failure in compiling the driver from the
mspec.
In [1] I extend the step of the parameter 'cpuSubFunction' since I require
it to indicate the subscription model. The change is in bold.
In [2] I select the type based on the 'cpuSubFunction'.
I try to generate the driver and the compiler sends me the message
indicated in [3]. It points to 'S7PayloadWriteVarRequest', but I haven't
touched it.
I appreciate your comments,
