Communication and Network Capabilities

• The 1769-L18ER-BB1B includes two Ethernet ports that act as an embedded switch with a single IP address.
• These ports support Linear, Star, and Device Level Ring (DLR) topologies for flexible networking.
• DLR provides fault-tolerant communication by automatically switching to a secondary path if a line fails.
• Linear topology offers a simple non-fault tolerant single line of devices.
• Star topology connects devices to a central hub or switch for easy expansion.
• The controller supports up to 32 sockets and 256 controller connections for complex communication tasks.
• A USB port allows temporary connections for programming and configuration.

Embedded I/O and Memory Features

• The 1769-L18ER-BB1B provides 16 sinking 24VDC digital inputs for connecting switches and sensors.
• It also includes 16 sourcing 24VDC digital outputs for driving relays and solenoids.
• You can expand I/O capability with up to eight 1734 POINT I/O modules using the 1734 backplane.
• The controller features 512KB of battery-free user memory thanks to an internal energy storage solution.
• A pre-installed 1784-SD1 Secure Digital card provides 1GB of non-volatile memory for program storage.
• You may upgrade the SD card to 2GB using the 1784-SD2 for additional storage capacity.
• The SD card includes a notch to lock or unlock write access to protect your data.
