The CPU 315-2 PN/DP is a CPU with medium-sized program memory. It is used in plants containing distributed automation structures in addition to a centralized I/O. It can be implemented as a PROFINET IO controller and as a standard PROFIBUS DP master in the SIMATIC S7-300. The 315-2 PN/DP CPU can also be used as distributed intelligence (PROFIBUS DP slave or PROFINET I-Device).

The CPU 315-2 PN/DP is an ideal platform for simple software-implemented technological tasks, e.g.:

• Motion control with Easy Motion Control.
• Implementation of control engineering tasks using STEP 7 blocks or runtime software Standard PID Control/Modular PID Control.

An extended process diagnosis is possible by using SIMATIC S7-PDIAG.

The integrated communication options of the CPU enable networked automation solutions to be implemented without additional components.
