I/O Assignment
For intra-device inputs I0 .. I3 as well as the outputs O0 ... O3 you can choose
between fixed or free assignment (see below).
Control via Profibus does not require an M option (M10 / M12).
If an M option is available, 12 inputs/outputs (ports) are freely assignable. These
can be configured as inputs or outputs by groups of four and be activated resp.
read via Object 121.2 and Object 133.3.
The signal inputs I4 ... I7 are fixedly assigned
If the respective functions are not needed, these inputs can also be used for
control.
I5 and I6 can, for example, be used as free inputs if the limit switch function is
deactivated.

Input-/Output extension
The display of the digital inputs in the optimization window of the C3 ServoManager
does not correspond to the physical status (24Volt=on, 0Volt=off) but to the logic
status: if the function of an input or output is inverted (e.g. limit switch, negatively
switching), the corresponding display (LED symbol in the optimization window) is
OFF with 24Volts at the input and ON with 0 Volts at the input.
