The CPU 319-3 PN/DP is the fastest S7-300 CPU with a large program memory. It is used in plants containing distributed automation structures in addition to centralized I/O. It is used, for example, as central controller in production lines or as machine controller with high processing speed demands.

Its quantity framework makes it optimally suitable for use of SIMATIC engineering tools, e.g.:

• Programming with SCL
• Sequence programming with S7-GRAPH

Furthermore, the CPU is an ideal platform for simple software-implemented technological tasks, e.g.:

• Motion control with Easy Motion Control
• Solving of closed-loop control tasks using STEP 7 blocks or standard/modular PID control runtime software

Enhanced process diagnostics can be achieved by using SIMATIC S7-PDIAG.

As a result of the CPU's integral communications facilities, networked automation solutions are possible without additional components.
