The CPU 1511T-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 1511-1T 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 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 PLCopen blocks. Furthermore, multiple SIMATIC S7-1500T Controllers can be synchronized with one another through cross-PLC synchronous operation.
