What this CPU carries
The 6ES7518-3FT10-0AB0 is the CPU 1518F-3 PN from Siemens' S7-1500 line, with a 0.3 ns bit performance and three independent interfaces—two PROFINET IRT with integrated 2-port switch and one Ethernet—making it suited for high-speed distributed control. Work memory is 18 MB for program and 150 MB for data. The CPU requires a SIMATIC Memory Card; no card is included, so factor that into your BOM.
