D–3Control Networks
Publication
1747-6.2
A device network connects plant floor devices directly to the control
system (e.g., 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.
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
A single scanner (master) can communicate with up to 63 nodes
(slaves) on DeviceNet. The SLC system supports multiple scanners
if more devices are required to be controlled by a single SLC 500
processor.
