ControlLogix DeviceNet Bridge Module and Linking Devices
Table 18 lists the available ControlLogix DeviceNet bridge and linking devices
that can be used with the DeviceNet network.
Software for DeviceNet Networks
Table 19 lists software that is used with the DeviceNet networks and modules.
Connections Over DeviceNet Networks
The ControlLogix controller requires 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 device data.
ControlLogix DeviceNet Module Memory
The 1756-DNB module has fixed sections of memory for the input and output
data of the DeviceNet devices on the network. Each device on your network
requires some input or output memory of the scanner. Some devices send and
receive data, so they need input and output memory. The 1756-DNB module
supports up to add the following:
• 124 DINTs of input data
• 123 DINTs of output data
