Product description

Siemens 6ES7317-6FF04-0AB0 is a SIMATIC S7-300 CPU 317F-2 DP for installed systems that combine standard control and failsafe functions on the S7-300 platform. Siemens specifies 1.5 MB of integrated memory, a 24-V-DC supply and two integrated RS-485 interfaces. The first supports MPI/DP at 12 Mbit/s, while the second operates as a DP master/slave interface. This configuration is relevant for systems in which distributed I/O, HMI devices and existing STEP-7 projects must be retained. The complete MLFB is essential for spare-parts procurement because the F-CPU type, memory capacity, firmware level and Distributed Safety configuration must match. Siemens documentation specifies STEP 7 V5.5 SP1 or a suitable STEP-7 version with HSP and Distributed Safety. Electrical data include nominal current consumption of 870 mA, typical idle consumption of 120 mA, an inrush current of 4 A and power dissipation of 4.5 W. The CPU requires a Micro Memory Card. Its width is 40 mm, height is 125 mm and depth is 130 mm; its weight is approximately 360 g. Before replacement, compare the hardware configuration, PROFIBUS addresses, safety signatures, MMC contents and engineering status. In safety-related S7-300 machinery, a visually similar standard CPU cannot replace the failsafe functions. The two integrated interfaces should also be checked against the actual wiring and communication structure before installation.

FAQ

Frequently asked questions

Contact us
Is this Siemens product available immediately?

Yes. The item is held in stock and can be prepared for dispatch shortly after receipt of the order.

Which details should I compare before replacement?

Compare the complete MLFB, hardware version, interfaces, existing engineering configuration and operating environment with the installed CPU.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
