The CPU 313C-2 DP is the compact CPU for systems with a distributed structure. Integrated digital inputs/outputs support direct interfacing with the process; the PROFIBUS DP master/slave interface supports connection to distributed I/O parts. The CPU 313C-2 DP can therefore be used both as a distributed unit for fast preprocessing and as a higher-level controller with a lower-level fieldbus system.

Other possible uses result from the integrated technological functions:

• Counting
• Frequency measurement
• Period measurement
• Pulse-width modulation
• PID control
