Tab.A/9: Slot 2: Channel−specific module parameters
With slot 3 you have indirect reading and writing access to
the data records (system parameters, module data and
module parameters). In order to do this, assign the 4 bytes of
the command box with: the slot number, the index number
and an offset (byte 4 is reserved).
You can then carry out the
read or write process with the Read Box and the Write Box.
