Structure of Variables in Simevents

With the realese of Matlab R2016b it is possible to access predefined variables in the workspace in Simulink or Simevents. This works pretty good for variables with a double structure or class. So I define a=1 in the workspace and my simulationblock in Simevents can use the variable a.
My question is: Can I access variables which are stored in datasets, cell arrays or tables directly as well?
I tried to access the variable by naming the dataset name (Mainvar.a). Unfortunately this does not work.
Thanks!
Lars

Unfortunately, datasets, cell arrays and tables in workspace are not currently supported in SimEvents Event Actions. It is worth noting that this is also a limitation of MATLAB function block and MATLAB coder (while cell array as input/output is allowed for MATLAB coder). Thus, you might want to convert your data into the supported types, such as scalar, matrix, structure, etc.

Thanks Mo Zhao!
A normal structure works well and is enough for my purposes

I actually have a problem even with a structure. I created a struct with 19 fields and I get an error, if i try to include it in simevents entity and server block. ROS(1).L2_3
if i type isstruct(ROS) or isstruct(ROS1) i get true, and but isvector(ROS(1).L2_3) is also true but i get the follwoing issue:
Data type of parameter 'ROS' is not supported in event actions. For more information about supported data types, see Supported data types in the documentation.
Yesterday it worked, and i can not remember, that i changed anything...
