SIMOTION C is a Motion Controller in S7-300 modular design. It already has four interfaces for analog or stepper drives and several digital inputs and outputs onboard. The C230-2 or the C240 can also be expanded with I/O modules from the SIMATIC S7-300 range. Two PROFIBUS interfaces with PROFIdrive and an Industrial Ethernet interface provide numerous options for the communications.
Compared to the C230-2 the C240 has a higher performance, increased memory sizes and an enhanced functionality of the onboard peripherals.

SIMOTION C provides the following benefits:

• Flexible use
  through utilization of the SIMATIC S7 range of modules and
  therefore optimum adaptation to the automation task
• Universal drive link
  for servo drives (digital and analog connection)
  or for stepper drives
• Easy to use
  through user-friendly operation and
  uncomplicated, fanless construction
