Schneider discontinued the VW3A21312 on 2023-10-02; no official successor is listed. The closest functional peer is the VW3A3315, which also uses a single LED but for fault indication rather than service/reference display. Choose VW3A3315 when the BOM requires a fault LED; otherwise the VW3A21312 remains the correct LonWorks card for Altivar 21 drives.","metaTitle":"Schneider VW3A21312 LonWorks communication card, discontinued","metaDescription":"Schneider VW3A21312 communication card for Altivar 21 drives, LonWorks protocol, TP/FT-10 topology, 78 kbps, discontinued since 2023-10-02.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Category":"US1CP4D22159","Topology":"TP/FT-10 (free topology)","Display type":"1 LED service Graphic display terminal reference received Graphic display terminal","lifecycle_stage":"mature","Transmission Rate":"78 kbps","Communication Service":"LonMark 6010: Variable Speed Motor Drive LonMark 0000: Node Object","Electrical connection":"3 ways removable screw terminal block","Nbr. of units in pkg.":"1","Product or Component Type":"Communication cards","Communication Port Protocol":"LonWorks"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$580.19","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/674f33948fb2f36a6887553f3ff31b4f.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/VW3A21312/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/VW3A21312","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/VW3A21312 when reusing this data.
