Siemens 6ES7151-8FB01-0AB0 SIMATIC ET 200S Fail-Safe PN/DP CPU
IM151-8F distributed fail-safe controller with integrated PROFINET connectivity.
Product Overview
Siemens 6ES7151-8FB01-0AB0 is an IM151-8F PN/DP CPU for the SIMATIC ET 200S distributed I/O system. The official data sheet specifies 256 KB integrated work memory, firmware V3.2 and an integrated PROFINET interface with three RJ45 ports operating as an IO Controller or I-device. The fail-safe CPU requires a SIMATIC Micro Memory Card and uses a 24 V DC supply. Procurement checks should cover the exact order number, hardware and firmware status, MMC contents, safety program, STEP 7 or TIA Portal engineering version, PROFINET configuration, optional DP master module and installed ET 200S station layout.

Compatibility and Procurement Checks
- Confirm the full 6ES7151-8FB01-0AB0 article number and hardware status.
- Match firmware V3.2 and approved engineering software.
- Review the fail-safe program, signatures, passwords and safety acceptance records.
- Verify the Micro Memory Card type, capacity and backed-up contents.
- Check all three RJ45 connections, PROFINET names, addresses and topology.
- Confirm 24 V DC supply and optional PROFIBUS DP master-module requirements.
- Compare the installed ET 200S module layout and request label photographs.
Lifecycle Note
The exact Siemens data sheet describes 6ES7151-8FB01-0AB0 as a “spare part” but does not provide a PLM lifecycle classification in the reviewed source. This page therefore preserves that official product note without converting it to Discontinued or another lifecycle term. Hardware, firmware, safety project and Micro Memory Card compatibility remain mandatory replacement checks.
