The CPU 1512SP F-1 PN is the CPU for standard and fail-safe applications with medium requirements in terms of processing performance and response speed in discrete production technology. The CPU 1512SP F-1 PN can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 3-port switch so that a linear topology can be set up in the system via Port 1 and 2, and so that a programming device/PC or HMI device can also be connected via Port 3.

When used as an I-Device, the CPU 1512SP F-1 PN enables distributed preprocessing of process data locally and only delivers the information actually required to the higher-level PLC. This has the following advantages:

Reduced load on the central PLC
Short response times to critical local signals
Less load on the bus system due to smaller data volumes
Faster set-up due to pretested units and parallel commissioning
Increased availability and flexibility due to autonomous machine units
Clear-cut configuration

The CPU 1512SP F-1 PN operates completely independently of the central PLC. If it fails, the CPU 1512SP F-1 PN simply continues running.

The bit-modular configuration of the ET 200SP I/O system, together with the CPU 1512SP F-1 PN, enables functionally oriented station configuration.

In addition, the CPU offers comprehensive control functionalities via easy-to-configure blocks as well as the ability to connect drives via standardized PLCopen blocks.
