The CPU 1510SP-1 PN is the cost-effective entry-level CPU for applications with medium requirements for processing speed and speed of response in discrete production technology. The CPU 1510SP-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 PG/PC or HMI device can also be connected via Port 3.

When used as an I-Device, the CPU 1510SP-1 PN enables distributed preprocessing of process data locally and only delivers the information actually required to the higher-level controller. This has the following advantages:

• Offloading of central controller
• 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 1510SP-1 PN operates completely independently of the central controller. If it fails, the CPU 1510SP-1 PN simply continues running.

The bit-modular design of the ET 200SP I/O system, together with the CPU 1510SP-1 PN, enables functionally oriented station design.

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