4.2.2.4 Profibus I/O Modules
This setting variant is exclusively reserved for the PROFIBUS DP module SK CU4-PBR or SK TU4- PBR…)
which is connected to the system bus. This setting enables the DP master to directly access the digital I/Os of
the module. In this 1 byte module, the digital outputs must be set as "output byte" and the digital inputs as
"input byte".
The "Profibus module I/O" must always be set to Slot 1 in the DP slave.
If the additional I/Os are not used, an "empty module" must be set on Slot 1.
The bits are allocated to the inputs and outputs as follows:
NOTE
The digital inputs of the PROFIBUS DP modules (SK CU4-PBR and SK TU4-PBR- …) cannot
be directly assigned with frequency inverter functionalities. These must be transferred via the
PROFIBUS and can be returned to the frequency inverter from the bus master via bits 8 and 9
of the control word by assignment of the required function in the BUS I/O In bits (P480 [-11] or
[-12]).
