Additional communication options include Ethernet, Profibus DP, Sy\/Max and other supported modules, subject to the configured hardware and connection limits.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 140CPU43412UC support Ethernet remote I\/O?\u003c\/p\u003e\n\u003cp\u003eA: The supplied specifications list zero Ethernet remote I\/O stations. Although Ethernet TCP\/IP connections are listed as supported locally, this should not be interpreted as native Ethernet remote I\/O station support.\u003c\/p\u003e\n\u003cp\u003eQ: What is the significance of the UC configuration?\u003c\/p\u003e\n\u003cp\u003eA: The complete reference identifies the conformal-coated Unity processor configuration. Schneider Electric identifies this product as a 1056 kB, 66 MHz coated Modicon Quantum Unity processor. Retain the complete 140CPU43412UC reference when checking replacement or procurement requirements.\u003c\/p\u003e\n\u003cp\u003eQ: Is the 140CPU43412UC discontinued?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Schneider Electric lists this reference as discontinued. Its published service status and end-of-service dates vary across regional product pages, so confirm regional support availability before planning maintenance or replacement. The manufacturer lists BMEP581020H as a recommended replacement, but this should be treated as a migration candidate rather than an automatically interchangeable module.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":67179066294387,"sku":"140CPU43412UC","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/140DRC83000C_Cocoai_3f2c2e24-5d0e-4eb1-bd01-f37000130a41.jpg?v=1794470426","url":"https:\/\/www.dcssupplier.com\/products\/unity-processor-schneider-electric-140cpu43412uc","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
