The CPU 319F-3 PN/DP is the fastest S7-300 CPU with a large program memory. It is ideally suited to plants with extensive automation tasks and stringent safety requirements.It can be implemented as a PROFINET IO controller and as a standard PROFIBUS DP master in SIMATIC S7-300. The CPU 319F-3 PN/DP can also be used as distributed intelligence (DP slave).Distributed I/O devices with fail-safe I/O modules can be connected over the three integrated interfaces. The fail-safe ET 200M I/O modules can also be installed in central and safety-related configurations.The integrated communication options of the CPU support networked automation solutions (also fail-safe) without the need for additional components.
