Allen Bradley 1747-SCNR SLC I/O Digital Modules

The 1747-SCNR is provided with Two (2) ControlNet ports, labeled as Channel A and Channel B. To establish connection to this port, ControlNet taps are required such as 1786-TPR Right angle T-Tap, 1786-TPS Straight T-Tap, 1786-TPYR Right Angle Y-Tap, and 1786-TPYS straight Y-Tap. To connect to the main ControlNet trunkline. The ControlNet trunkline used RG-6 Duad Shield cable with catalog number 1786-RG6. Additionally, BNC connectors may be needed to secure connection to the tapping ports. If an extended length of ControlNet media is required, coaxial repeaters may be used with catalog number 1786-RPCD. To simplify ControlNet connection, ControlNet Coax Tool Kit may be used.

The 1747-SCNR ControlNet address may be set from 01-99 with default value of 00. This default address is not a valid address which means, module default address requires modification. ControlNet address may be set via the provided rotary switches located on top of the scanner.
