CPU Fit for the Route
The Siemens 6ES7518-3AT10-0AB0 is an active-production CPU in the S7-1500 family with 12 MB of work memory for the program and 150 MB for data, so it handles big machine logic and tag-heavy data without breaking a sweat. Three PROFINET interfaces – two with integrated 2-port switches, all supporting IRT – let you wire drives and I/O in a linear or star topology without extra network hardware. Bit performance at 0.3 ns keeps isochronous loops tight. Don't forget the SIMATIC Memory Card – this CPU won't boot without one, and it's sold separately.
