Rockwell Automation 1771-SDN DeviceNet Scanner Module Installation Instructions - Manual (Page 11)

Publication 1771-IN014B-EN-P - September 2001
DeviceNet Scanner Module Catalog Number 1771-SDN/C 11
Note: The scanner module consumes/produces 8 bits of discrete
output/input for the processor connection. Therefore, the scanner
module cannot be placed next to a 16-point module when using
1-slot addressing.
3. Using a ball point pen or similar pointed object, adjust switches
7 and 8 to your desired chassis addressing mode. Slide the
switches up to denote an on or “1” position. Slide the switches
down to denote an off or “0” position. Make sure switches 1
through 4 and 6 in the switchbank labeled “Configuration”
always remain in the off or “0” position. For Series C
functionality, make sure switch 5 is in the on or “1”
position.

To set the scanner DeviceNet node address:
1. Locate the switchbank labeled “Channel 1”, on the left side of
the module.
2. Use the following table to determine the node address you want
to set for the module on Channel 1, and note your choice. The
address range is 0 to 63.
3. Using a ball point pen or similar object, adjust switches 3
through 8 to your desired node address settings. Slide the
