Example for determining all input/output bytes with F-modules
The table is only intended as an example and does not include all ET 200iSP modules. You
need to add the modules used as required.
Existing standard modules in ET 200iSP must also be taken into account (see the manual
"SIMATIC Distributed I/O ET 200iSP"
(https://support.industry.siemens.com/cs/ww/en/view/98821323)).
