Overview
BradCommunications
 eNetMeter
 DN is a passive device that continuously 
monitors a DeviceNet network and sends the information over Ethernet to a PLC 
or PC monitoring system. The information can be read directly by an 
EtherNet/IP
 master.  Optionally, data can be accessed through 
BradCommunications NetAlytix
 software, a DLL interface or an OPC server. 
 
 
 
 
 
 
 
 
 
 
eNetMeter DN provides extremely accurate measurements of the network 
parameters using high-speed sampling. By comparing acceptable baseline 
measurements of a “good” network, it can predict imminent failures down to 
individual devices. Measurements can be used in such a way, that when an OPC 
status tag is analyzed and is found to be outside the acceptable limits, steps can 
be taken to repair the system prior to any downtime. 
 
eNetMeter DN can be used to diagnose current faults on a non-functioning 
network through the measurement of hundreds of network parameters.  This can 
minimize downtime by pinpointing the node or location of the fault.  The data can 
also be stored to historian software for future analysis.  This is useful for 
companies typically involved with batching applications including pharmaceutical, 
food & beverage. If a problem occurs with a specific batch, the historical data can 
be viewed to see if any network problems occurred during the same time frame. 
This allows the company to then make any necessary adjustments to prevent re-
occurrences from happening in the future. 
Continuously monitor a DeviceNet
 network; measure, 
analyze and record network parameters to minimize 
network downtime.
