How can I read all the Siwarex data from the peripherie in SCL?

It is clear how the data from the Siwarex can be read from the peripherie and stored in a DB. In the examples a fewFC's (programmed in STL) and some DB's are used for these functions. In our projects we create custom blocks in SCL. The block to read the data and alarm-bits from the Siwarex must fit in our "standard" and has to be an FB. My question is this: how can I read all the Siwarex data from the peripherie in SCL? I would like to connect one I/O to an INPUT (ANY pointer?)of the FB: the starting address of the Siwarex I/O. The different items in the data-range should be written to OUTPUT-variables of the FB, so they can be used in the rest of the program. P.S.: I am an experienced S7-programmer. However I have rarely used pointers in SCL

Allthough I have not tried the examples yet, I have a question about them. All examples I find use the ANY-pointer to read and write data in DB's. Can the solutions in the examples also be used to read data from the peripherie? I guess it should be possible, because I have used Siwarex-U functions (created by "third party") before (in PCS7) which did just that.

I only cannot test it with a "live" Siwarex module, because I don't have one yet. One remark concerning the "Getting started" example: maybe it's a good idea to expand it with SCL-code? I would guess many people create their standard-blocks in SCL and it would make the examples better for them to understand and re-use.
