Siemens 6ES7511-1AL03-0AB0 SIMATIC S7-1500 CPU 1511-1 PN 300KB Programmable Logic Controller

The Siemens 6ES7511-1AL03-0AB0 is a SIMATIC S7-1500 CPU 1511-1 PN with 300 KB of work memory for program and 1.5 MB for data, a PROFINET IRT interface with an integrated 2-port switch, and a 6 ns bit-instruction processing time. It requires a SIMATIC Memory Card and connects up to 128 PROFINET IO devices.

Selection Notes

Firmware V4.1 needs TIA Portal V21, or V18 for FW V3.0, and an older TIA Portal can still configure it as a 6ES7511-1AK02-0AB0 for compatibility. The integrated 2-port PROFINET IRT switch lets it sit inline in a line topology without an external switch, and the 500 microsecond minimum isochronous OB6x cycle suits motion applications needing tight sync. At 300 KB program / 1.5 MB data memory and 128 IO devices, this CPU fits mid-size PROFINET stations - move up to a larger S7-1500 CPU if the program needs more memory or faster isochronous cycles are required.

Applications

Central controller for PROFINET-networked machines needing isochronous motion synchronization, media-redundant ring networking, and built-in web-server diagnostics without an added communication processor.
