EtherNet/IP Deterministic Networks & DLR Ring Execution

The dual Ethernet ports on the 1769-L18ER-BB1B utilize an integrated high-speed Ethernet switch that executes Device Level Ring (DLR) fault-tolerant network topologies. DLR implementation delivers sub-millisecond network recovery, ensuring deterministic message delivery between controller tasks and remote nodes during physical ring breaks. The onboard memory manager coordinates backplane bus communication velocity with firmware flash compatibility via Studio 5000 Logix Designer, maintaining precise time synchronization for up to 8 connected EtherNet/IP nodes across distributed control architectures.

Frequently Asked Questions

Q: Does the 1769-L18ER-BB1B backplane accept standard 1769 Compact I/O expansion modules?

A: No, the 5370 L1 series architecture exclusively supports 1734 POINT I/O modules for local expansion up to 8 total modules.

Q: How is non-volatile user memory maintained during an unpowered state?

A: The controller utilizes an included 1 GB industrial SD card for non-volatile program and tag retention, removing the requirement for internal lithium backup batteries.

Q: What is the maximum node capacity over the EtherNet/IP network interface?

A: The firmware allows up to 8 active EtherNet/IP nodes to communicate concurrently over the dual-port DLR network.

Field Installation Guidelines

Mount the 1769-L18ER-BB1B horizontally onto standard 35 mm DIN rail inside an IP54-rated enclosure. Wire the 24 VDC primary power lines directly to the integrated power terminals using 22 to 14 AWG copper conductors, ensuring correct polarity. Maintain at least 50 mm of functional clearance on all sides of the unit to ensure natural thermal convection. Connect the functional ground terminal directly to the cabinet ground bus bar with a low-impedance copper strap to mitigate high-frequency electromagnetic noise across the DLR network lines.
