SIMATIC S7-1500, CPU 1511-1 PN, central processing unit with 300 KB RAM for program and 1.5 MB for data, 1st interface: PROFINET IRT with 2 port switch, 25 ns bit performance, SIMATIC memory card required Please note the approvals and certificate in accordance with entry 109815653 on support.industry.siemens.com! The SIMATIC® S7-1500 advanced controller sets standards in terms of system performance and usability. The seamless integration of the SIMATIC S7-1500 controller into the Totally Integrated Automation Portal (TIA Portal) offers advantages such as shared data storage, a uniform operating concept and central services. This makes the use of cross-functional functions particularly easy. With its fast system response times, the controller ensures greater productivity in no time at all. For you, this means more flexibility and a shorter time to market. Various CPU versions are available for SIMATIC S7-1500, each in several performance classes. The portfolio includes standard CPUs, some with the option of integrating C/C++ code. The compact CPUs have integrated digital and analog IOs, and counting inputs and pulse outputs can be recorded directly on the CPU. The fail-safe CPUs enable standard and safety programs to be run on the same controller. The technology CPUs expand the motion control functions available in all SIMATIC S7-1500 controllers for sophisticated solutions. The SIMATIC S7-1500 advanced controller is configured using the SIMATIC STEP 7 Professional software. A SIMATIC memory card is required to operate this module.
