With the launch of Simatic S7-1500, Siemens has introduced a controller family of the next generation for medium to high-end machine and plant automation. The new generation of controllers is characterized by high performance and efficiency. Its characteristic features include outstanding system performance and a host of functions integrated as standard, including Motion Control, Security for maximum possible plant security, and Safety for safety applications that are easy to implement. Greater efficiency is represented in particular by the innovative design for simple commissioning and safe operation, the configurable diagnostic functions for the plant status and the integration into the TIA Portal for simple engineering and low project costs.The new generation of Simatic S7-1500 controllers is being launched on the market in stages. Initially, the portfolio will comprise the three CPU types 1511, 1513 and 1516 for the medium performance range, each also available as a F-version (failsafe) for safety applications, with graded performance features. These differ, for example, in the number of interfaces, bit performance and the size of the display and data memory. The new controller generation Simatic S7-1500 expands the range of Siemens controller with two new Failsafe CPUs. Failsafe CPUs are designed for high-level applications: CPU 1518-4 F-PN/DP and 1516-3F-PN/DP. CPU 1515-2 PN is designed for mid-level applications in machine and plant automation.
