It provides a native 10Base-T Ethernet port alongside an RS-232 serial interface for DH-485, DF1, or ASCII communications, enabling both networked control and legacy device integration on the same CPU. As a SLC 5\/05 CPU, it executes ladder logic within 64K of user memory and is typically programmed with RSLogix 500. In typical installations, the L553 plugs into a SLC 500 rack with other I\/O modules, offering Ethernet connectivity for plant-wide monitoring, remote I\/O access, or PLC-to-PLC communication without requiring a separate Ethernet module. The 1747-L553 is one of the SLC 5\/05 processors (along with the 1747-L551 and 1747-L552) that combine an Ethernet port and RS-232 port in a single CPU, making it a suitable choice for maintaining legacy automation while adding network access. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659697586478,"sku":null,"price":4785.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ae2098a6-7b34-469e-a2fe-40067e09484e.jpg?v=1769529745","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1747-l553-slc-500-ethernet-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
