Product details

The 6ES7511-1AK01-0AB0: Process image is 32 kbyte each for inputs and outputs — enough for a compact machine but not a large plant floor. Built-in PROFINET port handles MRP (Automanager, Manager, Client per IEC 62439-2), LLDP, MRPD when IRT is active, and Modbus TCP. Ladder, FBD, STL, SCL, GRAPH all supported; plus and for temperature and valve control without a separate loop controller. Note: no PROFIsafe on this CPU — safety functions require an external F-CPU or F-modules.

Fieldbus and network integration

Single PROFINET port at 100 Mbps, IRT-capable. Supports DCP, DNS, DHCP, HTTP/HTTPS, SNMP, I&M data (I&M0 to I&M3). MRP Automanager means the CPU can act as ring manager without an external switch — simplifies cabling and reduces component count. Up to four communication modules (CM/CP) can be inserted for expansion to PROFIBUS, additional PROFINET, or Ethernet interfaces.

Width 35 mm, depth 129 mm, height 147 mm — fits a single-wide slot on the S7-1500 backplane. DIN-rail mount. Commissioning features: forcing, diagnosis LEDs (ERROR, MAINT), I&M data for asset tracking.

Frequently asked questions

Does the 6ES7511-1AK01-0AB0 support DCP?

Yes, DCP (Discovery and Configuration Protocol) is supported for PROFINET device configuration.

Does it support DNS?

Yes, DNS is supported for hostname resolution in the network.

What programming languages are available on this CPU?

LAD, FBD, STL, SCL, and GRAPH are all supported.

Is Modbus TCP supported?

Yes, Modbus TCP is supported via the built-in PROFINET port.

What MRP modes does this CPU support?

MRP Automanager, MRP Manager, and MRP Client per IEC 62439-2 Edition 2.0.
