The 1747-SDN DeviceNet Scanner Module is designed for use with SLC 500 systems. Before installation, ensure you have a personal computer with Windows 2000 or later, RSNetWorx for DeviceNet (version 2.22 or later), and RSLogix 500 software. The module must be installed in an SLC 1746 chassis with an SLC 5/02 or later processor.
Hardware Features
The module features a front-facing access door, a 10-pin linear plug for DeviceNet connection, and status indicators. The indicators include a Module Status LED and a Network Status LED, along with a two-digit numeric display for diagnostic codes.
Installation
Follow these steps to install the module:
- Turn off the chassis power supply.
- Select a slot in the SLC 1746 chassis (any slot except the leftmost, which is reserved for the processor).
- Insert the module into the slot and apply firm, even pressure to seat it in the backplane connectors.
- Connect the DeviceNet drop line to the 10-pin linear plug, matching the wire colors to the label (Red: +24V, White: Can_H, Shield: Drain/Shield, Blue: Can_L, Black: +24V Return).
- Insert the plug into the DeviceNet port on the module.
LED Indicators and Troubleshooting
The module provides visual feedback via bicolor LEDs:
- Module Status (MODULE): Green indicates normal operation. Flashing green means the module is not configured. Flashing red indicates invalid configuration. Solid red indicates an unrecoverable fault.
- Network Status (NET): Green indicates normal communication. Flashing green means the channel is enabled but no communication is occurring. Flashing red indicates a slave device communication failure.
The numeric display flashes diagnostic codes at 1-second intervals. Common codes include:
- 0-63: Normal operation (node address).
- 70: Duplicate Node Address check failed.
- 72: Slave device stopped communicating.
- 73: Identity mismatch (electronic key).
- 91: Bus-off condition detected.
Technical Specifications
The module operates in a Pollution Degree 2 industrial environment. Power requirements are 5V DC (500 mA) from the backplane and 24V DC (90 mA) for DeviceNet. Operating temperature range is 0 to 60 °C (32 to 140 °F).
