Line up the circuit edges with the chassis guide tracks, pushing firmly back until both the upper and lower plastic retaining tabs snap securely onto the metal structure to support the unit against plant floor vibrations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-Volatile Flash Configuration:\u003c\/strong\u003e To protect your 32MB application code against power failures, insert a compatible CompactFlash card into the front memory slot.

If the 1756-BA2 lithium battery dies while the chassis loses power, the volatile 32MB memory will drop its program. To prevent this downtime, we highly recommend storing a permanent copy of your application logic on an optional CompactFlash card.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can the 1756-L65 communicate directly over EtherNet\/IP out of the box?\u003c\/strong\u003e\u003cbr\u003e\nA2: The processor only features a built-in RS-232 serial port. To link the 1756-L65 to an EtherNet\/IP network, you must add an adjacent Ethernet communication module, such as the 1756-EN2T or 1756-ENBT, into the same ControlLogix backplane chassis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Does the 0.35 kg mechanical weight place limits on where I can install the card inside the chassis?\u003c\/strong\u003e\u003cbr\u003e\nA3: Not at all. The compact 0.35 kg balance is distributed across a single-slot standard width footprint. Thanks to its native direct backplane connection system, it operates with full efficiency in any open slot location of your rack, though slot 0 is the common engineering standard for the main CPU.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51050298474628,"sku":"1756-L65","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1756-L65-2.jpg?v=1785156279","url":"https:\/\/www.etowonauto.com\/de\/products\/allen-bradley-1756-l65-controllogix-5565-processor-32mb-memory","provider":"Etowon Auto","version":"1.0","type":"link"}
