Frequently Asked Questions
Q: Is the 6ES7412-3HJ14-0AB0 compatible with TIA Portal?
A: Yes. This CPU supports programming and configuration via both SIMATIC STEP 7 V5.6+ and TIA Portal V15.1 and above.
Q: What is the difference between 6ES7412-3HJ14-0AB0 and 6ES7412-3HJ00-0AB0?
A: The -0AB0 suffix denotes the standard version. The HJ14 designates the specific hardware revision with updated firmware support and enhanced PROFINET functionality compared to earlier HJ00 variants.
Q: Can this CPU be used in a redundant S7-400H configuration?
A: The CPU 414-3 PN/DP is not the dedicated H-series CPU. For full redundancy (S7-400H), the 6ES7414-4HM14-0AB0 (CPU 414-5H) is recommended. However, this module can operate within non-redundant S7-400 systems alongside fault-tolerant I/O.
Q: Do you supply new, refurbished, or used units?
A: We supply new original, factory-refurbished (with warranty), and tested-used units depending on availability. Condition is clearly stated in the quotation.
Q: What is the typical lead time?
A: In-stock units ship within 3–5 business days. For sourced units, lead time is typically 7–15 business days depending on origin and destination.
Q: Can you provide a certificate of origin or test report?
A: Yes. Full traceability documentation is available upon request for all orders.
