Leading-edge diagnostic tools for DeviceNet industrial networks use high-speed

Leading-edge diagnostic tools for DeviceNet industrial networks use high-speed
data sampling to predict system faults for avoiding plant automation down times
Brad® 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 eNetMeter™
DN provides extremely accurate measurements of the network parameters using high-speed
sampling. By comparing acceptable baseline measurements of a known, standard network, it
can predict imminent failures down to individual devices and proactively respond to out-oftolerance parameters.
The information can be read directly by an EtherNet/IP™ master. Optionally, data can be
accessed through Brad® NetAlytix™ software, a DLL interface or an OPC server. For

FEATURES AND BENEFITS
eNetMeter™ DN
• Continuous high-speed measurement (up
to 100 mega-samples per second) of
critical network parameters (CAN signals,
power and shield voltage)
• Accurate analysis of DeviceNet physical
layer parameters to avoid pending network
issues
• DeviceNet data is monitored using a passive
device, i.e. does not consume a MAC ID
• Has no adverse effect on the network being
monitored
• Data is available via Ethernet
(10/100 Mbaud TX)
• Standard and flexible communication for a
variety of applications using a PLC and/or PC
• Presents both detailed and summary
(macro) data related to DeviceNet either
for the entire network or broken down by
individual nodes
• Users can implement a basic solution and
progress to a more detailed resolution as
required
• Compact IP20 housing can be DIN-rail or
direct-panel mounted
• Easy installation, including retro-fit
applications
• Portable test unit is easy to use on multiple
networks
• Cost-effective approach, particularly for
OEMs and system integrators
