AB 1771-ASB High Speed Remote I/O Subsystem Link

AB 1771-ASB High Speed Remote I/O Subsystem LinkProduct Overview The Allen Bradley 1771 ASB functions as the primary communication link for distributed control topologies within the Rockwell Automation PLC 5 architecture. This network interface card populates the leftmost slot of a remote 1771 I O chassis, establishing a high speed data connection back to a central PLC 5 processor over the Allen Bradley Remote I O (RIO) network. The 1771 ASB scans peripheral discrete and analog I O modules plugged

This fine granularity prevents mechanical jitter in sensitive applications like printing or high-speed labeling where inconsistent torque commands cause material waste

Network Interface: Communicates via Vnet/IP through the rack bus

The unit supports comprehensive firmware flash compatibility
