Product details

Field Integrator's Quick View

The 6ES7516-2GN00-0AB0: Process-image capacity is 32 kB for both inputs and outputs — all I/O bytes update in a single cycle, making it a fit for medium-sized safety applications.

Panel Fit & Network Configuration

Physical dimensions are 135 mm wide, 130 mm high, and 65 mm deep. On the PROFINET side: MRP Automanager per IEC 62439-2, MRP Client, and MRPD (requires IRT partner). Also supports MODBUS TCP, UDP, TCP/IP, HTTP/HTTPS (standard and user pages), SNMP, LLDP, DHCP, DNS, and DCP for line-topology discovery. Built-in hardware clock and I&M data (I&M0 through I&M3) for asset tracking and diagnostics.

Frequently asked questions

What PROFIsafe version does this CPU support?

The CPU supports PROFIsafe V2.4 and V2.6, enabling fail-safe communication with standard and high-feature safety I/O.

Does the CPU support DCP and DNS for PROFINET?

Yes, DCP and DNS are both supported, required for automatic device naming and topology discovery in a PROFINET IO system.
