Remote I/O Passthru
DeviceNet Network
A DeviceNet network connects plant floor devices directly to the
control system (for example, SLC 500 controller) reducing the number
of I/O interfaces and wiring associated with a typical hard-wired
solution. The DeviceNet communication network is a completely
open device network and has the support of industry’s leading sensor,
actuator, and control manufacturers.
The 1747-SDN DeviceNet Scanner
In a typical configuration, the 1747-SDN DeviceNet Scanner acts as an
interface between DeviceNet devices and the SLC 5/02, SLC 5/03,
SLC 5/04, and SLC 5/05 processors. The scanner communicates with
DeviceNet devices over the network to:
• read inputs from a device.
• write outputs to a device.
• download configuration data.
• monitor a device’s operational status.
The scanner communicates with the SLC 500 processors to exchange
I/O data. Information exchanged includes:
• device I/O data.
• status information.
• configuration data.

The SLC 5/03 OS302 or later, SLC 5/04 OS401 or later, and SLC
5/05 processor support remote I/O passthru via both their
communication ports.
