SIPLUS S7-1500 CPU 1518-4 PN/DP with conformal coating based on 6ES7518-4AP00-0AB0 . Central processing unit with Work memory 3 MB for Program and 10 MB for data, 1st interface, PROFINET IRT with 2-port switch, 2nd interface, Ethernet, 3rd interface, Ethernet, 4th interface, PROFIBUS, 1 ns bit-performance, SIMATIC Memory Card required The SIMATIC® S7-1500 Advanced Controller sets new standards with regard to system performance and usability. The seamless Integration of the SIMATIC S7-1500 Controller in the Totally Integrated Automation Portal (TIA Portal) offers advantages, such as common data storage, a uniform operating concept and central services. This makes the use of universal functions particularly easy. With its short system response times, the controller boosts productivity in the twinkling of an eye. For you, this means more flexibility and a shorter product launch time. The SIPLUS extreme variant also protects the automation system components from harsh ambient conditions, such as extremely high and low temperatures, corrosive gases, condensation, frost and biologically, chemically and physically active substances that can occur in control cabinets or container solutions in the production area. This also reliably protects your challenging automation tasks and provides additional investment security. The SIMATIC S7-1500 Advanced Controller is configured using the SIMATIC STEP 7 Professional software. A SIMATIC Memory Card is required for the operation of this module.
