Siemens 6ES7964-2AA01-0AB0 is the SIMATIC S7-400 IF 964-DP interface module documented for PROFIBUS DP communication. Siemens technical documentation identifies an isolated RS-485 physical interface, a 9-pin D-sub connector and transmission rates from 9.6 kbit/s to 12 Mbit/s. The module receives its power from the CPU and is intended for approved S7-400 CPU configurations. Before installation or replacement, verify the complete order number, CPU compatibility, interface slot, PROFIBUS address, baud rate, bus termination, connector wiring and the approved hardware configuration.
Condition, availability and warranty are Stockoems commercial information, not manufacturer commitments.

Confirm the approved S7-400 CPU and interface slot.
Check the isolated physical interface and connector wiring.
Match address, transmission rate and bus termination.
Validate the configured station and communication diagnostics.
Adding an approved DP interface to a compatible S7-400 CPU.
Connecting verified PROFIBUS DP field stations.
Restoring an existing documented IF 964-DP configuration.
Diagnosing wiring, termination and station communication.
Verify the complete 6ES7964-2AA01-0AB0 order number, compatible S7-400 CPU, interface slot, RS-485 wiring, PROFIBUS address, baud rate, cable length and bus termination before replacement. A similar IF 964-DP order number is not automatically interchangeable. Installation should be performed by qualified personnel with the system safely isolated.
It is the SIMATIC S7-400 IF 964-DP Interface Module identified by this exact Siemens order number.
Siemens specifies an isolated RS-485 interface through a 9-pin D-sub connector.
The official S7-400 CPU manual specifies 9.6 kbit/s to 12 Mbit/s.
Check CPU compatibility, interface slot, address, baud rate, connector wiring, cable length and bus termination.
Stockoems provides a one-year commercial warranty under written order terms; this is not a Siemens manufacturer commitment.

Documented communication channel
Our workflow combines inspection planning, label verification, compatibility documentation, protective handling, logistics coordination, customs-file preparation and after-sales communication. Product identity and visible label data are compared with the order. Packaging is selected for the item and route, while tracking and shipping documents are coordinated for the destination. Specific stock quantities and delivery timing are provided only through written commercial communication.
Choose a supplier that preserves the complete model, explains condition clearly, requests label evidence and separates commercial terms from manufacturer specifications.
Request written identity, quantity, condition, warranty terms, packaging scope, shipping basis, customs documents and return authorization rules.
Provide installed labels, CPU order number, interface slot, PROFIBUS address, baud rate, connector details, network drawing and fault records.
Shortened model strings, copied data from similar products, unclear condition language, unverifiable quantities, missing label evidence and absent return terms require caution.
Send the complete part number, required quantity, destination country and clear product-label photographs for documented review.
