DeviceNet Network Integration Solution – Allen-Bradley 1747-SN | SLC 500 Platform
The Allen-Bradley 1747-SN is the factory-standard DeviceNet Scanner Module for the SLC 500 programmable controller platform. Designed for engineers who need deterministic, high-speed device-level communication across distributed I/O, drives, sensors, and actuators, this module serves as the master node on a DeviceNet network — polling up to 63 slave devices with configurable scan rates and explicit messaging support.
At Konmask.com, we supply the 1747-SN to MRO procurement teams, system integrators, and OEM rebuild programs requiring verified, shelf-ready inventory with full traceability documentation.

- Multi-Connection Support — Simultaneous polled + COS + explicit messaging on the same network segment without bandwidth conflicts
- RSNetWorx Configuration — Graphical node commissioning, EDS-based device configuration, and online diagnostics via RSNetWorx for DeviceNet
- Fault Isolation — Per-node fault reporting in SLC data file allows ladder logic to isolate and respond to individual device failures without halting the entire network
- Long Cable Runs — DeviceNet trunk supports up to 500 m at 125 Kbps, suitable for large plant floor layouts
- Proven Longevity — Installed base spanning 25+ years; extensive third-party documentation, trained integrators, and spare parts ecosystem

Application-Specific FAQ
Q: Can the 1747-SN operate as a DeviceNet slave instead of a master?
A: No. The 1747-SN is a scanner (master) only. For slave functionality in an SLC 500 rack, use the 1747-SDN (DeviceNet Interface Module).
Q: How many 1747-SN modules can I install in one SLC 500 chassis?
A: Multiple scanners can be installed in the same chassis (subject to backplane current budget), each managing an independent DeviceNet network segment — useful for large systems requiring network segmentation.
Q: Is the 1747-SN compatible with SLC 5/01 and 5/02 processors?
A: The 1747-SN requires an SLC 5/03 (Series C or later), 5/04, or 5/05 processor. It is not compatible with SLC 5/01 or 5/02 due to M0/M1 file requirements.
Q: What RSNetWorx version is required for configuration?
A: RSNetWorx for DeviceNet version 4.x or later is recommended. EDS files for all connected slave devices must be installed in the RSNetWorx EDS library prior to configuration.
Q: Can I replace a failed 1747-SN without re-configuring the network?
A: Yes, if the replacement module is loaded with the same configuration file (saved from RSNetWorx). The SLC processor will resume normal scanning after the module is seated and powered.
Q: Do you supply the 1747-SN with a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all verified units. Extended warranty options are available — contact us for details.
Q: Can you supply multiple units for a plant-wide MRO stocking program?
A: Yes. We support blanket orders, scheduled releases, and consignment stocking arrangements for high-volume MRO customers. Contact our procurement team to discuss terms.
