The structure of the objects is as follows:
Index 2: Module Parameters
Index 2 can be used on some modules to change parameters during operation,
e.g., to adjust a measuring range. Changing parameters during operation is not
permitted for all modules.
Failsafe and configuration values can be specified here for each I/O module. Slot
"1 to 63" should be selected to create a reference to the I/O module. In the end it
is the NIU that makes the connection to the master and therefore index 2 is the
parameter that refers to the I/O modules, which is stored on the NIU.
