Description
Configured for high-speed EtherNet/IP client/server data exchange in 1769 CompactLogix platforms, the Allen-Bradley MVI69-DFNT (MVI69-DFNT Master Communication Module) provides direct physical/electrical execution. It establishes a dedicated bridge between CompactLogix backplanes and EtherNet/IP devices, drawing an 800 mA current load at 5 VDC and occupying a single slot on the 1769 rack.

Backplane Bus Communication Velocity and Determinism
The module interfaces directly with the 1769 backplane using optimized backplane bus communication velocity drivers to ensure deterministic read/write block transfers. Operates with explicit 5 VDC bus power routing, requiring strict adherence to the 2-slot power supply distance rating limit to prevent voltage drop under peak 800 mA loads. Firmware flash compatibility across RSLogix 5000 v16.03 or later ensures synchronous I/O data table mapping and prevents buffer overflow during high-density packet routing over EtherNet/IP networks.
Frequently Asked Questions
Q: What is the maximum power supply distance rating for the MVI69-DFNT on a 1769 bus?
A: The module has a strict power supply distance rating of 2 slots. It must be installed within 2 slots of a 1769 power supply to ensure proper 5 VDC voltage stability under full 800 mA backplane loading.
Q: Does the MVI69-DFNT require external power wiring, or is power supplied via the backplane?
A: All operating power (800 mA at 5 VDC) is drawn directly from the 1769 CompactLogix backplane. No external 24 VDC power connections are required for basic module operation.
Q: What firmware and software requirements exist for L43 and L45 controller support?
A: Compatibility with CompactLogix L43 and L45 processors requires RSLogix 5000 version 16.03 or later to establish standard 1769 backplane assembly messaging and data block transfers.
Field Installation Guidelines
- Backplane Insertion: Turn off system power before mounting or removing the module. Align the module lock lever, slide onto the DIN rail, and snap the 1769 bus connectors firmly together. Secure the DIN-rail latch.
- Power Distance Compliance: Position the module within 2 slot locations of the system power supply (e.g., 1769-PA2, 1769-PB2, 1769-PA4) to avoid voltage starvation on the 5 VDC bus line.
- Ethernet Cabling & Grounding: Connect CAT5e or CAT6 industrial-shielded twisted-pair (STP) cables via the front RJ45 port. Ensure proper drain wire grounding at the patch panel to maintain 1500 V RMS galvanic isolation integrity.
- Clearance & Thermal Management: Maintain a minimum clearance of 50 mm (2 inches) above and below the module chassis for natural convection cooling inside the enclosure.
