Replacement & Compatibility FAQ
Q: Is 6ES7131-0BL00-0XB0 discontinued?
A: This module is from the ET 200L legacy series. Siemens has transitioned to ET 200SP, but the original module remains available through authorized surplus suppliers including Konmask.com.
Q: Can I replace it with a 6ES7131-6BL01-0BA0 (ET 200SP)?
A: Not directly — ET 200SP uses a different backplane and interface module. A system migration is required. Contact us for a migration assessment.
Q: Does this module work with TIA Portal?
A: Yes, in legacy/compatibility mode. Full native support requires STEP 7 Classic (v5.x).
Q: What is the warranty on your supplied units?
A: We offer a 12-month warranty on all units. Defective units are replaced or refunded within the warranty period.
Q: Do you provide a certificate of conformity?
A: Yes, upon request for B2B orders.
