Allen-Bradley 1747-SDN Pass Through driver
The 1747-SDN Pass Through driver provides access to DeviceNet through a 1747-SDN/SLC (5/03 or higher) module pair for a host computer. Using this driver, the host computer can transact on DeviceNet when it has a connection to a processor rather than a direct connection to the DeviceNet network. The 1747 Rack, in which the processor resides, must also contain a 1747-SDN (1747 DeviceNet Scanner) module to enable this access. 1747-SDN Revision 4.015 is required.
IMPORTANT:
To enable pass through access through a 1747-SLC, you must use RSLogix 500 to configure the M0 and M1 files, which are associated with the 1747-SDN, to be a minimum of 361 words in length. You can access the M file configuration by launching I/O Configuration within RSLogix 500, and then selecting the appropriate 1747-SDN. The M file size changes must be downloaded to the SLC. Also, the SLC must be placed in
