Siemens 6ES7511-1CK00-0AB0 is the SIMATIC S7-1500 compact CPU 1511C-1 PN and is listed by Siemens as a spare-part product. Its integrated configuration includes 16 digital inputs, 16 digital outputs, five analog inputs, two analog outputs and high-speed counter functions. Siemens also lists a PROFINET IRT interface with a two-port switch and requires a SIMATIC Memory Card. This page supports maintenance and controlled replacement of installed units. Because Siemens shows a successor article, buyers should compare hardware, firmware, TIA Portal requirements, integrated-I/O wiring and project compatibility before any change.
