Overview Manuals Safety Logic MPI/DP Ports Memory Layout F-DB Restrictions

Features:

  • The CPU 317F-2 DP provides 1024 KB of work memory for standard and safety programs.
  • An MPI/DP interface and a second DP master/slave interface separate communication roles.
  • A SIMATIC Micro Memory Card and S7 Distributed Safety engineering are required.
Siemens 6ES7317-6FF03-0AB0 executes standard and fail-safe logic as the central processing unit in a SIMATIC S7-300 station.

Its first MPI/DP connection and second PROFIBUS DP master/slave interface must be restored with their original network parameters.

The safety project, Micro Memory Card, F-DB handling, hardware release, and firmware context belong together during exchange.

The Siemens 6ES7317-6FF03-0AB0 SIMATIC S7-300 CPU 317F-2 DP may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Fail-Safe Processing Context

  • Application scope: The CPU is designed for personnel, machine, and burner safety tasks.
  • Safety software: Use S7 Distributed Safety V5.2 SP1 or higher with the documented STEP 7 environment.
  • Consistency control: Resolve an inconsistent safety program before returning the CPU to operation.
  • Version record: The product information covers hardware release 01 and firmware V2.1.10 onward.

Two-Interface Bus Layout

  • First interface: MPI/DP communication is supported up to 12 Mbit/s.
  • Second interface: The second PROFIBUS connection can operate as DP master or slave.
  • Restoration record: Preserve station addresses, baud rates, termination, and device assignments for both interfaces.

Work and Process Memory

  • Work memory: The CPU provides 1024 KB for program execution.
  • Process image: Inputs and outputs each use a 1024-byte process-image area.
  • Retentive data: Up to 256 KB of data blocks can be configured as retentive.
  • Load storage: A SIMATIC Micro Memory Card is required.

Safety Data-Block Boundaries

  • Creation control: F-DBs must be generated and handled through the supported safety engineering workflow.
  • Deletion control: Manual changes to F-DB structure can invalidate safety-program consistency.
  • Retentive data: Verify F-DB retentivity and startup behavior against the archived safety project.
  • Exchange rule: Preserve the project signature, MMC contents, and documented CPU version together.
Description
Built for a SIMATIC S7-300 station, Siemens 6ES7317-6FF03-0AB0 is the CPU 317F-2 DP central processing unit that executes both standard control and fail-safe applications for personnel, machines, and burner systems.

Program execution on 6ES7317-6FF03-0AB0 uses 1024 KB of work memory and a required SIMATIC Micro Memory Card, with safety-program data blocks excluded from the RAMtoROM copy operation.

For 6ES7317-6FF03-0AB0, F-DBs cannot be created or deleted by the restricted system functions, and read/write operations cannot target an F-DB address.

Communication duties on 6ES7317-6FF03-0AB0 are divided between an MPI/DP interface up to 12 Mbit/s and a second PROFIBUS DP interface that can operate as master or slave.

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.
How does the RAMtoROM function treat safety data blocks on 6ES7317-6FF03-0AB0?
For 6ES7317-6FF03-0AB0, RAMtoROM does not copy safety-program data blocks from work memory into load memory.
Why can an inconsistent safety program prevent normal use of 6ES7317-6FF03-0AB0?
The safety logic of 6ES7317-6FF03-0AB0 must remain consistent; unsupported F-block or F-DB changes require correction and a valid safety compilation before operation.
Which network settings should be captured from 6ES7317-6FF03-0AB0 before exchange?
Record the 6ES7317-6FF03-0AB0 MPI/DP and second DP interface addresses, baud rates, master/slave roles, bus termination, and connected stations.
How much retentive data can be configured on 6ES7317-6FF03-0AB0?
The documented limit for 6ES7317-6FF03-0AB0 is up to 256 KB of retentive data blocks, subject to the project and safety-data restrictions.
What should be preserved before modifying F-DBs for 6ES7317-6FF03-0AB0?
Back up the complete 6ES7317-6FF03-0AB0 safety project, MMC contents, safety signature, CPU version, and existing F-DB configuration before any change.
Is the Siemens successor automatically plug-compatible with 6ES7317-6FF03-0AB0?
No automatic equivalence should be assumed for 6ES7317-6FF03-0AB0; review the 6ES7317-6FF04-0AB0 hardware, firmware, safety project, and interface requirements.
