- Description
The Siemens 6ES7518-3TT10-0AB0 CPU 1518T-3 PN is the top-end technology CPU in the SIMATIC S7-1500T motion-control line, holding 18 MB of program memory and 150 MB of data memory. It carries three PROFINET interfaces — two with integrated 2-port IRT switches and a third for basic services — and processes bit operations in 0.3 ns.

Selection Notes
T marks this as a technology CPU for motion control, and it sits at the top of the S7-1500T range: 18 MB of program memory and 150 MB of data memory give it roughly three times the 1517T-3 PN's capacity, along with a faster 0.3 ns bit-operation time and a shorter 125 µs minimum isochronous cycle for tighter axis synchronization. Drop to the 1517T-3 PN instead once the project's axis count and data volume fit comfortably within its smaller memory budget, since it costs less for the same PROFINET IRT and IO-controller feature set. Choose an F-series S7-1500 CPU instead if the requirement is safety logic rather than motion technology.
