What capabilities does the SIMOTION C have?  
The SIMOTION C is a motion control module for the control of servo drives.  
As of V3.2, stepper drives with a pulse-direction interface can be connected to the onboard 
drive interfaces. 
The following configurations can be selected: 
●  C230-2 and C240: Up to four axes via the onboard drive interface or 
●  C230-2, C240 and C240 PN: Axes via PROFIBUS DP or 
●  C240 PN: Axes via PROFINET IO or 
●  Mixed operation with a maximum of four axes via the onboard drive interface (C230-2, 
C240) and additional axes via PROFIBUS DP 
The number of operable axes on the PROFIBUS DP or PROFINET IO depends on the 
system cycle clock settings, i.e. more axes can be operated with longer cycle times. 
The SIMOTION C controllers are powerful modules for positioning independent single axes 
or motions in an axis grouping. 
Both rotary axes and linear axes can be operated.
