Communication Interface
Module This document is a user guide for the 1757-ABRIO module, which lets
Rockwell Automation controllers (ProcessLogix or ControlLogix)
communicate with Allen-Bradley remote I/O. The module acts as a
RIO network scanner. The 1757-ABRIO module facilitates connection
to analog and discrete I/O devices as well as any block transfer
modules.
