The EtherNet\/IP stack manages up to 16 EtherNet\/IP nodes, 120 TCP connections, and 256 total controller connections while hosting up to 4 axes of CIP Motion over Ethernet. Firmware processing supports up to 32 controller tasks with 100 programs per task, ensuring predictable scan timing across both discrete embedded I\/O points and backplane bus communication velocity with local 1769 expansion modules.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the maximum number of local 1769 expansion modules supported by the 1769-L27ERM-QBFC1B?\u003c\/p\u003e\n\u003cp\u003eA: The controller supports a maximum of 4 local 1769 Compact I\/O expansion modules attached directly to the right side of the main unit assembly.\u003c\/p\u003e\n\u003cp\u003eQ: Does this controller require a lithium battery to back up user program memory during power loss?\u003c\/p\u003e\n\u003cp\u003eA: No. The CompactLogix 5370 L2 series uses non-volatile flash memory supported by an internal energy storage module, eliminating the maintenance requirements of traditional lithium batteries.\u003c\/p\u003e\n\u003cp\u003eQ: Can the two EtherNet\/IP ports be configured with two separate IP addresses for subnet isolation?\u003c\/p\u003e\n\u003cp\u003eA: No. The two physical RJ45 ports function as an embedded switch sharing a single network interface and IP address, designed primarily to support fault-tolerant Device Level Ring (DLR) and linear daisy-chain network topologies.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the controller onto a standard 35 mm DIN rail or fasten it directly to an enclosure backplate using M4 hardware. Ensure the enclosure provides clean, filtered air to maintain ambient operating temperatures between 0 and 60 deg C. Connect the embedded power supply terminals to a regulated 24 VDC power source with short, thick conductors to minimize voltage drop under peak current loads. Terminate all field wiring for the embedded digital, analog, and high-speed counter channels into the designated terminal blocks, keeping signal lines physically segregated from high-voltage AC cables and VFD drive power conductors. Ensure proper shield grounding at the terminal block chassis connections to prevent noise coupling on universal analog input loops (voltage, current, thermocouple, RTD).\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52906147348792,"sku":"1769-L27ERM-QBFC1B","price":188.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/295.jpg?v=1788485951","url":"https:\/\/www.automodulexpert.com\/products\/1769-l27erm-qbfc1b-allen-bradley-5370-l2-motion-controller","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
