應用

The CPU 1511-1 PN is the cost-effective entry-level CPU for standard and fail-safe applications with medium requirements for processing speed and speed of response in discrete production technology. With its RAM size, this CPU is also suitable for medium-sized applications. It can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as 2-port switch so that a linear topology can be set up in the system. 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.
