Standard DeviceNet Connections
If you use standard DeviceNet I/O with your GuardLogix controller, you need
to allocate two connections for each 1756-DNB module. One connection is
for module status and configuration. The other connection is a rack-optimized
connection for the DeviceNet I/O data.
To use the 1756-DNB module to access standard data via the DeviceNet
network, you must use RSNetWorx for DeviceNet software to do the
following:
• Create a configuration file for the network.
• Configure each standard device on the network.
• Configure the 1756-DNB.
• Add the standard I/O devices to the 1756-DNB scan list.
When you add the 1756-DNB module to the I/O Configuration of the
controller, the Logix Designer application automatically creates a set of
standard tags for the input, output, and status data of the network.
