The 1771-OBD and 1771-OBC modules from Allen Bradley (a Rockwell Automation brand) are commonly associated with ControlLogix systems, but they are not specifically for Ethernet communication. However, these modules may support communication and data exchange over Ethernet, but generally they are used more for I/O (input/output) functions.


To be specific:


1771-OBD: This may be a discrete output module for converting the digital signal of a PLC (programmable logic controller) into a physical output, such as a control motor, indicator light, etc. It may support multiple output types and configurations, depending on the model and version of the module.

1771-OBC: The specific description of this module may vary by model and version, but is generally similar to the 1771-OBD and may be a discrete output module with a different configuration.

For Ethernet communication, Allen Bradley provides specialized communication modules, such as the 1756-ENBT, which are used to enable Ethernet communication between the ControlLogix system and other devices.


For accurate information about the 1771-OBD/C and 1771-OBC modules, including their features, specifications, and compatibility, it is recommended that you consult Allen Bradley's official documentation or contact its technical support department. This will help you better understand the applicability and performance of these modules in your particular application.
