About the Siemens 6ES7317-6FF04-0AB0

The Siemens 6ES7317-6FF04-0AB0 is the CPU 317F-2 DP, a fail-safe S7-300 CPU. Siemens's data sheet gives it 1.5 MB of integrated work memory, a combined MPI/PROFIBUS DP interface at 12 Mbit/s and a second PROFIBUS DP interface, and says it is used with the software package S7 Distributed Safety V5.2 SP1 or higher. The program is held on a Micro Memory Card. Siemens's data sheet marks it as a spare part.

What is the 6ES7317-6FF04-0AB0 used for?

It runs larger machine and line programs together with their safety functions, with fail-safe I/O on PROFIBUS DP. As a fail-safe CPU its safety program and configuration must be checked against the replacement before it goes back into service.

Lifecycle and successor

Discontinued.

Before you order

What to photograph or confirm so the right unit is quoted.

Check the full order number and the firmware version on the CPU's label, and read the program size from the project if you can: a replacement must match or exceed the work memory. The Micro Memory Card (MMC) holding the program is a separate part; send its order number and size too.

Alternatives for 6ES7317-6FF04-0AB0

The manufacturer’s named successor and other parts in the same family. None is a drop-in replacement without checking wiring, I/O and configuration for your installation.
