Product details

Mid-range S7-1500 with dual PN and MRP ring capability

The 6ES7516-2PN00-0AB0: Programming via LAD, FBD, STL, SCL, or GRAPH — all supported natively. MODBUS TCP is also baked in, so you can talk to legacy instruments or drives without an external gateway. Process image is 32 kbytes for inputs and 32 kbytes for outputs — enough for a medium-sized machine with distributed I/O over PROFINET. Temperature tolerance: -40 to 70 °C ambient, so it lives in cold warehouses or warm cabinets without derating.

Integration notes from the field

Supports I&M data (I&M0 to I&M3) for asset tracking and consistent device replacement. Forcing of I/O is allowed during commissioning — useful for quick tests. Two onboard PROFINET ports share a single MAC; layer 2 forwarding is handled internally. No external passive device needed for MRP rings — the CPU can act as the ring manager.

Frequently asked questions

When sourcing 6ES7516-2PN00-0AB0, what's the closest functional second-source — 6ES7516-3AN01-0AB0?

The 6ES7516-3AN01-0AB0 is a direct family sibling with identical form factor and basic specs, but it adds IRT support. That makes it the functional upgrade where deterministic motion or MRPD is required. For projects that don't need IRT, this -2PN00 is the cost-optimised drop-in.

What is 6ES7516-2PN00-0AB0's listed DCP?

DCP is supported (Discovery and Configuration Protocol). That means you can set the device name and IP address via the network using Siemens tools like PRONETA without needing a separate interface.

What is 6ES7516-2PN00-0AB0's listed DNS?

DNS is supported. The CPU can resolve hostnames to IP addresses over the PROFINET network, simplifying tag-based addressing in larger plants.
