SIMATIC S7-1500, CPU 1518-4 PN/DP, CENTRAL PROCESSING UNIT WITH WORKING MEMORY 4 MB FOR PROGRAM AND 20 MB FOR DATA, 1. INTERFACE, PROFINET IRT WITH 2 PORT SWITCH, 2. INTERFACE, ETHERNET, 3. INTERFACE, ETHERNET, 4. INTERFACE, PROFIBUS, 1 NS BIT-PERFORMANCE, SIMATIC MEMORY CARD NECESSARY

The CPU contains the operating system and executes the user program. The user program is located on the SIMATIC memory card and is processed in the work memory of the CPU. The PROFINET interfaces on the CPU allow simultaneous communication with PROFINET devices, PROFINET controllers, HMI devices, programming devices, other controllers and other systems. CPU 1518-4 PN/DP supports operation as an IO controller and I-device. Similarly to the PROFINET interface, the PROFIBUS interface available on the CPU allows communication with other devices. When you use the interface as PROFIBUS DP interface, the CPU on the PROFIBUS DP also assumes the role of a DP master.
