Allen-Bradley 1771-SDN Pass Through driver

The 1771-SDN Pass Through driver provides access to DeviceNet through a 1771-SDN module pair for a host computer. Using this driver, the host computer can transact on DeviceNet when it has a connection to a PLC-5 rather than a direct connection to the DeviceNet network. The 1771 Rack, in which the PLC-5 resides, must also contain a 1771-SDN (1771 DeviceNet Scanner) module to enable this access.
