What Your 1747-SDN
Module Does In a typical configuration, the 1747-SDN module acts as an interface
between DeviceNet devices and the SLC 500 processor.
Typical DeviceNet Network
The 1747-SDN module 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 1747-SDN module communicates with the processor in the form
of M1/M0 File Transfers and/or Discrete I/O. Information exchanged
includes the following:
•
Device I/O data
•
Status information
•
Configuration data
A processor to I/O DeviceNet configuration is shown in the following
figure. See the referenced chapters for more information.
