Q1: Is the 6ES7417-4XL04-0AB0 still in production?
No. This CPU was discontinued by Siemens on January 1, 2021 . It is now available only through aftermarket suppliers and as spare parts for existing installations. The official replacement is the 6ES7417-4XT07-0AB0, which offers 30 MB work memory (15 MB code + 15 MB data) compared to the 20 MB of this model .
Q2: What is the difference between 6ES7417-4XL04-0AB0 and 6ES7417-4XT07-0AB0?
The 6ES7417-4XT07-0AB0 is the direct successor with increased work memory (30 MB vs. 20 MB). Both CPUs have the same processing speed (0.03 µs bit operations), MPI/DP interfaces, and two plug-in IFM module slots. The 4XT07 is recommended for new installations and as the migration path for discontinued 4XL04 units .
Q3: What software is required to program this CPU?
The 6ES7417-4XL04-0AB0 requires STEP 7 V5.2 SP1 HF3 or higher with the appropriate Hardware Update (HW-Update) . It supports STEP 7 Classic (V5.x) and is not directly configurable in TIA Portal – users have reported difficulties finding it in TIA Portal V14 hardware catalog .
Q4: Can this CPU be used in redundant (H) systems?
No. The 6ES7417-4XL04-0AB0 is a standard (non-redundant) CPU. For redundant high-availability applications, the CPU 417-5H series (e.g., 6ES7417-5HT06-0AB0) is required, which supports S7-400H fault-tolerant configurations with bumpless switchover .
Q5: What are the common causes of "SF" (System Fault) LED errors?
Common causes include:
Firmware/configuration mismatch: Ensure the hardware configuration matches the actual firmware version (V4.0)
Memory Card issues: Verify the Memory Card (FLASH/RAM) is properly inserted and formatted
Battery failure: The CPU uses a backup battery to buffer all data; check battery voltage and replace if needed
Bus communication errors: Check PROFIBUS DP cable, connectors, and termination
