The XT variant (L84EXTS) includes 20 MB of standard memory and 6 MB of safety memory, a USB port, a 1 Gb embedded Ethernet port capable of connecting up to 250 EtherNet\/IP devices, and a 4‑character alpha\/numeric display for on‑board status. To achieve SIL 3 \/ PLe, it operates with a separate safety partner in a 1oo2 architecture, typically pairing with a safety module such as 1756-LSP. It is designed to work with the ControlLogix 1756 backplane and is installed in GuardLogix cabinets; conformal coating and the XT designation indicate protection for extreme or corrosive environments. As of late 2026, Rockwell notes the GuardLogix 5580 XT controllers may be discontinued after December 31, 2026, so availability should be confirmed with a distributor.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658922328366,"sku":null,"price":4600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1b6b4e95-6755-4dee-b45b-501f24b5cd43.jpg?v=1769525594","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1756-l84exts-guardlogix-xt-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
