More Information

Overview Manuals Network Record Remote I/O Commissioning Scanner & Adapter Modes Application
  • Operates in documented Universal Remote I/O scanner or adapter mode
  • Uses scheduled connections for digital, block-transfer, analog, and specialty data
  • Supports up to 32 racks and is discontinued with no planned Rockwell Automation replacement

1756-RIO is an Allen-Bradley ControlLogix Universal Remote I/O scanner/adapter module.

In scanner mode it exchanges scheduled data with remote adapters; in adapter mode it emulates one or more racks for an installed scanner and can monitor other racks.

Preserve the Logix project, scanner/adapter mode, rack map, block-transfer definitions, baud rate, cable route, termination, and adapter inventory before replacement or migration.

Availability, condition, price, and shipping time for 1756-RIO are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Record every remote adapter, rack address, and network segment before exchange
  • Preserve the approved scanner schedule in the controller project archive
  • Identify cable routing and termination at each serviced network section
  • Verify scanner and adapter communication before machine-output operation
  • Test the installed rack inventory against the accepted Remote I/O project
  • Investigate a missing rack from its address, adapter, cable, and schedule records
  • Configure scanner mode when 1756-RIO owns scheduled connections to installed Remote I/O adapters
  • Configure adapter mode when the ControlLogix chassis must emulate one or more racks for an existing scanner
  • Use the accepted rack map and scheduled connection definitions instead of MSG instructions
  • ControlLogix scanner-mode systems communicating with legacy Remote I/O adapters
  • Adapter-mode systems emulating one or more Remote I/O racks for an installed scanner
  • PLC-5, PLC-3, or SLC migration projects retaining existing Universal Remote I/O wiring
Description
1756-RIO is a discontinued Allen-Bradley ControlLogix Universal Remote I/O communication module that can operate as either a scanner or an adapter.

Scanner mode exchanges scheduled data with legacy Remote I/O adapters. Adapter mode lets a ControlLogix chassis emulate one or more racks for an existing scanner and monitor additional racks on the network.

Before replacement or migration, preserve the operating mode, Logix project, rack map, block-transfer definitions, baud rate, cable route, termination, adapter inventory, firmware, and observed network state.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 1756-RIO communicate with a remote chassis merely because the cable is connected?
No. The scanner, remote adapter, rack address, cable route, termination, and controller project must form a compatible documented Remote I/O system.
What should be recorded before replacing a 1756-RIO scanner?
Preserve the controller project, rack-address records, adapter catalog numbers, network drawing, cable/termination details, firmware record, and observed fault state.
Why can 1756-RIO remain faulted after a replacement module powers up?
Check the Remote I/O schedule, adapter address, cable continuity, termination, scanner configuration, and firmware/project compatibility; power alone does not establish a valid network.
Can Allen-Bradley 1756-RIO operate only as a scanner on a Universal Remote I/O network?
No. Rockwell Automation documents both scanner and adapter modes. Scanner mode controls scheduled rack connections, while adapter mode lets a ControlLogix chassis emulate racks for an existing scanner; preserve the selected mode and complete rack map before replacement.
How should 1756-RIO network changes be tested after replacement?
Verify the remote rack inventory and communication state in a controlled maintenance window before re-enabling any machine outputs.
Why is lifecycle review important before sourcing 1756-RIO?
Rockwell Automation lists 1756-RIO as discontinued with no planned replacement, so the installed network and support strategy must be reviewed before procurement.
Can 1756-RIO directly replace any older Remote I/O scanner?
No. Confirm the complete controller system, remote adapters, configured communication behavior, and installed project before treating a scanner as a direct replacement.
