Quickly identify problems relating to network power, data errors and excessive bandwidth consumption for your
DeviceNet* network.
Live-Network Validation and Troubleshooting
Imagine diagnostic tools that can cut downtime resulting from network failure and can help anticipate potential
problems. Molex diagnostic tools let you respond instantly to network faults, enabling a control engineer or
electrician to swiftly isolate and diagnose a fault source. Quickly identify problems relating to network power,
data errors and excessive bandwidth consumption. Molex diagnostic tools help certify new DeviceNet industrial
network installations, speed DeviceNet maintenance and repairs and prevent plant automation downtime by
predicting faults. Molex offers a number of DeviceNet diagnostic tools to minimize network downtime.
eNetMeter™ for DeviceNet
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 used to proactively respond to out-of-
tolerance parameters before network failure occurs. Optionally, data can be accessed through BradCommunica-
tions™ NetAlytix™ software, a DLL interface or an OPC server.
For additional details related to eNetMeter DN please, refer to the Molex/Brad datasheet, order number:
DW2008250.
NetMeter
®
for DeviceNet
NetMeter cuts troubleshooting time by providing the technical detail a DeviceNet troubleshooting expert needs.
Yet it simplifies and summarizes, allowing a DeviceNet novice to effectively identify and diagnose network
problems. NetMeter uses a patented integrated intelligence technique to summarize multiple DeviceNet bus
operational variables into a single health index. It summarizes DeviceNet bus health by displaying a happy face
icon, indicating a healthy network; a sad face, indicating a serious problem; or a neutral face, indicating nominal
performance (a good indication to repair things before they actually fail). NetMeter then walks the user through
each fault condition and its source.
Power Monitor
®
for DeviceNet
Power Monitor monitors DeviceNet power quality at any cable junction. To install, simply replace a „T“ or „in-
line“ connector with a Power Monitor. Green lights indicate a good working DeviceNet voltage level. A red light
shows that the voltage is too high - check the power supply. A blue light warns that the voltage is too low - your
cabling is too long or the DeviceNet node is loading down the network. And a yellow light indicates excessive
noise - check for bad wiring connections or noise sources too close to the network.
LED Termination Resistor
Termination resistors are required on each of the trunk line in a DeviceNet installation. Molex provides both
male and female terminators; the correct installation depends on which gender is required on the end of your
trunk line. The LED Termination Resistor also allows you to determine and confirm the correct polarity. The
green LED is hooked up to V+ and V-. A red LED indication is the result of an incorrect (polarity) installation.
Power Tap
Power taps allow power to be quickly connected to the network. It distributes power to two 4A networks by
providing a means to quickly and simply connect one power source. By separately fusing the two segments each
of the two sections can be independently diagnosed. In addition the LEDs provided on the power tap tell if each
of the segments has the correct polarity connected. A male connection on the drop power connection insures safe
installation by not having live power on the connection from the power supply. A green LED indication tells you
the power is correctly connected while a red light LED clearly indicates reverse polarity.™
