More Information

Overview Manuals DP Roles Cable Limits Data Exchange Service Path

Features:

  • Adds an independent PROFIBUS DP channel to an S7-400 CPU.
  • Supports both DP master and DP device operating roles.
  • Keeps the fieldbus connection electrically isolated from the internal electronics.
The IF 964-DP occupies the CPU interface slot and exchanges data through its dual-port memory rather than through a separate external controller.

Device addresses and process-data areas are assigned in the S7 hardware configuration, allowing the same hardware to take either side of a PROFIBUS link.

Network reach depends on the selected bus speed, so the cable plan and transfer rate must be considered together when the segment is configured.

The Siemens 6ES7964-2AA01-0AB0 IF 964-DP PROFIBUS Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Selecting the bus role

  • Master mode: The module coordinates cyclic data exchange with configured DP slaves.
  • Device mode: The interface presents assigned input and output areas to an external DP master.
  • CPU dependency: The usable station count follows the limits of the installed S7-400 CPU.
  • Configuration: The operating role and station parameters are set in the S7 hardware project.

Relating rate to segment length

  • Low rate: At 9.6 kbit/s, a segment can extend to 1200m.
  • High rate: At 12 Mbit/s, the corresponding segment limit is 100m.
  • Intermediate settings: Each supported transmission rate has its own permitted cable distance.
  • Planning point: The selected rate therefore determines the physical boundary of the PROFIBUS segment.

Moving process data through the interface

  • Shared memory: Dual-port RAM forms the transfer area between the CPU and PROFIBUS processor.
  • Input direction: DP input data is made available to the S7 program through assigned address areas.
  • Output direction: CPU output data is transferred from the address area to the configured DP station.
  • Consistency: The configured data length defines which bytes belong to each device transaction.

Accessing interface functions

  • Bus connector: The isolated PROFIBUS port carries the configured fieldbus segment.
  • Status review: Interface states can be evaluated during commissioning through the S7 project.
  • Parameter storage: The hardware configuration supplies the operating parameters after startup.
  • Module identity: The IF 964-DP order number distinguishes this interface from other S7-400 communication modules.
Description
The Siemens 6ES7964-2AA01-0AB0 is an IF 964-DP communication interface for the SIMATIC S7-400 platform. It provides a separate PROFIBUS DP channel that can operate as a DP master or as a DP device.

A 256 KB dual-port memory transfers process data between 6ES7964-2AA01-0AB0 and the CPU. The interface supports as many as 125 DP devices when the selected CPU permits that station count, with up to 244 input bytes and 244 output bytes assigned to each device.

Bus timing for 6ES7964-2AA01-0AB0 extends from 9.6 kbit/s to 12 Mbit/s. The permitted cable length changes with the transmission rate, reaching 1200m at 9.6 kbit/s and 100m at 12 Mbit/s, while the PROFIBUS connection remains electrically isolated from the internal electronics.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can Siemens 6ES7964-2AA01-0AB0 remain offline after the PROFIBUS cable is connected?
A role, station address, and transmission rate must be assigned to Siemens 6ES7964-2AA01-0AB0 in the S7 hardware project before cyclic exchange can start.
How should the cable length be checked for Siemens 6ES7964-2AA01-0AB0?
Match the selected PROFIBUS rate to its permitted segment distance for Siemens 6ES7964-2AA01-0AB0; 12 Mbit/s is limited to 100m.
Can Siemens 6ES7964-2AA01-0AB0 be configured as a DP device instead of a master?
Yes. Siemens 6ES7964-2AA01-0AB0 supports both DP master and DP device roles, but only the role stored in the hardware configuration is active.
What limits the number of stations handled by Siemens 6ES7964-2AA01-0AB0?
The selected S7-400 CPU and its configured resources determine the usable station count for Siemens 6ES7964-2AA01-0AB0, up to 125 DP devices.
Where is process data exchanged when Siemens 6ES7964-2AA01-0AB0 is installed?
A 256 KB dual-port memory transfers the configured input and output areas between Siemens 6ES7964-2AA01-0AB0 and the CPU.
