Information About 1747-SN

The 1747-SN is an Allen-Bradley communication module that is used to implement Remote I/O (RIO) communication between RIO protocol enabled devices such as PanelView graphic operator terminals, message display, SLC500 controllers, other Programmable Logic Controller (PLC) and 3rd party devices such as gateways and protocol converters. This communication module is specifically a Scanner module, communicating with compatible RIO adapter modules to request I/O status update, messages and diagnostics over the RIO network.

The 1747-SN comes with One (1) RIO communication port. This port is a Three (3) pin terminal that requires a specific communication cable such as the Belden 9463 cable. RIO protocol may be implemented physically at a maximum wire length of 3050 meters or 1050 ft where supported connections are up to Sixteen (16) devices when operating in normal mode and Thirty-Two (32) devices in complementary mode. This scanner module is able to transfer data at a transmission rate of 57.6 Kbaud with cable length of 3048 meters and 230.4 Kbaud rate with cable length of 762 meters. Devices are connected in daisy-chain topology with both ends terminated using an 82 Ohm resistor.

The 1747-SN supports downloading, uploading and commissioning of the SLC500 controller as well as data transfer to connected graphic terminal in the network. It also supports remote I/O passthru.

The 1747-SN uses the node’s extended capability to transfer information in the communication channel at a rate of 57.6 Kbaud through a cable length of 3048 meters (10,000 feet) and at a rate of 230.4 Kbaud through a maximum distance of 762 meters (2500 feet) cable using an 82-Ohm terminating resistor. Information is also transmitted with the node’s non-extended capability at rates of 57.6 Kbaud and 230.4 Kbaud through a cable distance of 3048 meters (10,000 feet) and 762 meters (2500 feet) using an 82-Ohm 1/2 Watt terminating resistor. It has four selectable baud rates and it uses 2 DIP switches (Switch 1 and 2) for the selection of baud rates. The 1747-SN’s operating temperature range is between 0 and 60 degrees Celsius at 5 to 95% humidity without condensation and it has a non-operational temperature between -40 degrees Celsius and 85 degrees Celsius.

Frequently Asked Questions about 1747-SN
Question: What is the Allen-Bradley 1747-SN used for?
Date Update:16/06/2025
Answer:

The Allen-Bradley 1747-SN is a Remote I/O (RIO) Scanner Module designed for use within SLC 500 systems. It enables high-speed communication between SLC processors, Human Machine Interfaces (HMI), PanelView displays, and other RIO-enabled devices. Operating over a Belden 9463 cable, the module facilitates real-time I/O data transfer, diagnostics, and control messaging in distributed automation networks. It is often deployed in applications that require modular, scalable communication across multiple industrial control components. With a single RIO port, it simplifies network structure while supporting robust and reliable data exchange.

Question: Which devices are compatible with the 1747-SN?
Date Update:16/06/2025
Answer:

The 1747-SN is built for interoperability within the Allen-Bradley ecosystem and beyond:

  • Compatible with SLC 5/02, 5/03, 5/04, and 5/05 processors.
  • Communicates with PanelView terminals, remote I/O adapters, and message displays.
  • Interfaces with third-party RIO adapters, protocol converters, and gateways.
  • Fully supported in 30-slot chassis systems.

This broad compatibility ensures seamless integration into a variety of legacy and modern industrial systems.

Question: How is the communication cable configured for this module?
Date Update:16/06/2025
Answer:

The communication cable setup follows strict industrial standards:

  • Uses Belden 9463 twisted-shielded pair cable.
  • Supports up to 3048 meters (10,000 feet) at 57.6 Kbaud.
  • Requires daisy-chain topology with 82-ohm terminators at both ends.
  • Baud rate and topology affect cable length and number of devices.

Proper termination and shielding are essential for signal integrity across long distances.

Question: How to wire 1747-SN?
Date Update:16/06/2025
Answer:

Wiring the 1747-SN requires attention to cable type and topology:

  • Use Belden 9463 cable or equivalent twisted shielded pair.
  • Follow daisy-chain topology, connecting one device after another.
  • Terminate both ends with 82-ohm, ½ watt resistors.
  • Connect the cable to the 3-pin terminal on the module.
  • Ground the shield at one point only to avoid noise loops.

Correct wiring ensures stable, interference-free communication across all RIO devices.

Question: Is the 1747-SN still in production?
Date Update:16/06/2025
Answer:

Yes, the Allen-Bradley 1747-SN is still in production and officially supported by Rockwell Automation. It remains part of the SLC 500 ecosystem, although new systems are increasingly built with CompactLogix or ControlLogix.
