Siemens 6ES7517-3TQ10-0AB0 SIMATIC S7-1500T CPU 1517T-3 PN 6MB/50MB Technology Programmable Logic Controller

Siemens designed the 6ES7517-3TQ10-0AB0 CPU 1517T-3 PN as a rack-mounted technology CPU in the SIMATIC S7-1500T motion-control line, sized for machines with axis and kinematics control needs. It runs 6 MB of program memory and 50 MB of data memory, and carries three PROFINET interfaces — two with integrated 2-port IRT switches for isochronous axis traffic and a third port reserved for PROFINET basic services.

Selection Notes

T marks this as a technology CPU built for motion control: it executes axis, cam and kinematics technology objects that a standard PN/DP CPU cannot run natively. Against the 1518T-3 PN at the top of the line, this CPU's 6 MB program memory and 50 MB data memory size it for machines with a moderate axis count; move up to the higher-memory 1518T once the project's axis count or data volume outgrows this budget. Choose the F variant of the S7-1500 family instead if the need is safety logic rather than motion technology, since the T-CPU carries no F-block support.
