SIMATIC S7-1500 compact CPU CPU 1511C-1 PN, central module with 175 KB RAM for program and 1 MByte for data, 16 digital inputs, 16 digital outputs, 5 analog inputs, 2 analog outputs, 6 fast counters, 4 fast outputs for PTO/PWM/frequency output 1. Interface: PROFINET IRT with 2 port switch, 60 ns bit performance, including push-in front connector, SIMATIC memory card required 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 overarching 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.
