The Siemens 6ES7516-3AN01-0AB0 is a SIMATIC S7-1500 CPU 1516-3 PN/DP central processing unit designed for demanding industrial automation tasks. It provides 1 MB of program work memory and 5 MB of data work memory, with 10 ns typical bit performance. Integrated communications include a PROFINET IRT interface with a two-port switch, a second PROFINET RT interface and a PROFIBUS interface. A SIMATIC Memory Card is required. Siemens classifies this complete order code as a spare-part product following product cancellation, so suffix, firmware, engineering version and installed-system compatibility should be checked carefully before replacement.
Condition, availability and warranty are Stockoems commercial terms. The lifecycle wording follows the Siemens catalog.

Our service workflow supports procurement teams, engineers and maintenance personnel from model review through documented delivery and after-sales communication.
Model and suffix verification compares the requested code with order information. Product and label photo confirmation checks visible identification details before dispatch.
Condition confirmation records the offered commercial condition, while the inspection workflow reviews housing, connectors, labels and accessible product details.
Technical compatibility review considers suffix, revision, firmware, engineering environment, interfaces and installed-system requirements supplied by the customer.
Check whether the supplier verifies the complete model and suffix, states the commercial condition clearly, provides product and label photos, documents warranty terms and explains the return authorization process.
Request the exact order code, visible label information, hardware and firmware details when applicable, interface compatibility and confirmation of the installed engineering environment.
Common risks include incomplete suffixes, reused photos, missing labels, vague condition statements, unsupported technical claims, unclear warranty scope and requests to ship returns without authorization.
Share the complete part number, quantity, destination country and label photos so our team can review the order requirements.
