Communicate over Networks
Connections over DeviceNet
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.
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 either some input or output memory of the
scanner. Some devices both send and receive data, so they need both
input and output memory. The 1756-DNB module supports up to:
•
124 DINTs of input data.
•
123 DINTs of output data.
