Product Summary
The 1747‑SDN is a single-slot DeviceNet Scanner Module for SLC 500 controllers. It bridges the processor with up to 63 nodes at 125 Kbps. Use poll, strobe, change-of-state, cyclic, or pass‑through modes for flexible data exchange.
Theme A: Product Procurement & Buyer Guide
Procurement managers need a module that integrates smoothly with existing SLC 5/02 or later processors. The 1747‑SDN fulfills this requirement perfectly. It draws only 500 mA from the 5 V backplane and 90 mA from the 24 V supply. This low power consumption reduces your panel’s thermal stress. The module operates in slave mode and supports M1/M0 file transfers. It also works with discrete I/O for simple applications. For advanced setups, the pass‑through feature replaces legacy 1770‑KFD or 1784‑PCID connections. This upgrade cuts hardware count and simplifies network architecture. You can drive up to 63 nodes on a single DeviceNet segment. The baud rate of 125 Kbps meets most factory floor speed requirements. Each node connects via the included 1787‑PLUG10R linear plug. The module’s open‑style enclosure is c‑UL‑us and CE certified. Use it in temperatures from 0 to 55 °C with non‑condensing humidity up to 95%. Vibration resistance of 5 g at 10‑500 Hz ensures reliability on moving machinery. Shock rating of 30 g protects during startup and fault events. Choose this scanner to unify your DeviceNet devices without costly gateways.
Theme B: Step-by-Step User & Installation Guide
Installing the 1747‑SDN is straightforward when you follow these steps. First, ensure your SLC chassis has a free slot. The module occupies a single slot and mounts on a DIN rail or panel. Slide it into the chassis until the locking tab clicks. Next, connect backplane power using the chassis power supply. The module draws 500 mA at 5 V DC and 90 mA at 24 V DC. Open the front access door to reach the DeviceNet terminal. Insert the 1787‑PLUG10R linear plug into the 10‑pin port. Wire your DeviceNet trunk cable to the plug following standard pinout. Set the node address on the LCD display before power‑up. The display also shows error codes during operation. Two LED indicators—Module Status and Network Status—give real‑time diagnostics. Green means normal, red signals a fault. For pass‑through configuration, use SLC 5/03, 5/04, or 5/05 processors only. Configure the scanner using RSLogix 500 software. Select poll, strobe, change‑of‑state, or cyclic I/O based on your device needs. The module automatically scans I/O and exchanges data with the processor. Test the network by verifying that all 63 nodes report correctly. This installation takes less than 30 minutes for experienced technicians. Follow these steps to achieve a reliable DeviceNet backbone.
