Industrial Control & Drive Integration

The 1747-SN governs cyclic network data exchange synchronized with the backplane bus communication velocity properties of the local SLC chassis. By serving as an interface controller, the hardware facilitates wide-area I/O density scaling routines, bridging remote adapters and rack assemblies over deterministic physical pathways. Integrating this scanner within hybrid architectures alongside newer Profinet / EtherNet/IP deterministic networks requires strict verification of firmware flash compatibility across the host SLC processor and communication bridges to prevent token-rotation latencies, transmission drops, or remote block mapping faults.

Frequently Asked Questions

Q: Does the 1747-SN support online extraction or Insertion Under Power (RIUP)?

A: No. The SLC 500 backplane infrastructure does not support hot-swapping. The rack power supply must be entirely isolated before inserting or removing the module. Attempting installation while the backplane is energized can cause physical degradation of internal logic components or network port transceivers.

Q: What are the layout constraints regarding network line termination for this module?

A: The RIO link requires appropriate resistor termination at both physical ends of the trunk line to eliminate signal reflections. The specific resistance value (82 Ohm or 150 Ohm) must be selected according to the baud rate configuration (57.6, 115.2, or 230.4 kbaud) and cable type utilized.

Field Installation Guidelines

Chassis Slot Allocation: Insert the 1747-SN module into any available I/O slot of a local SLC 500 chassis except Slot 0, which is reserved for the processor. Align the printed circuit board side rails with the chassis tracks and guide the module forward until the locking tabs snap firmly into position.
Network Wiring Protocols: Land the RIO blue hose conductor wires to the designated terminal block connectors according to standard terminal pinouts (Blue wire, Shield, Clear wire). All wiring infrastructure within hazardous locations must strictly adhere to NEC Article 501-4(b) guidelines.
Shield Grounding and Noise Suppression: Secure the RIO network shield drain wire to a single, clean structural earth ground point. Ensure that the SLC 500 chassis frame is directly bonded to the main enclosure functional ground bar with a low-impedance conductor to preserve NEMA ICS 2-230 noise immunity parameters.
