DeviceNet™ NetMeter DeviceNet NetMeter™ DeviceNet™ Netmeter DeviceNet™ Specifications • Diagnostic/troubleshooting tool • Analyzes both power and bit stream information • Hand held with simple user interface Diagnostics The DeviceNet NetMeter empowers untrained personnel to diagnose and • Empowers untrained troubleshoot network installations personnel to diagnose quickly and easily, without risk. and troubleshoot the Completely passive on the network, network quickly POWER SUPPLY: CONNECTORS: and easily the meter analyzes the data and power lines on your DeviceNet net- BAND RATES: ANALOG ACCURACY ANALOG RANGE: • Simplifies network wide work. In seconds, both network-wide and device specific and device-specific traffic as well as information with easy power monitoring information is user interface for fast captured and displayed on a simple, diagnostics and straightforward user interface. Auto troubleshooting Search checks bus errors, bus traffic, • Certifies proper bus power voltage, shield voltage, operation of new common mode voltage, CAN_H/L DeviceNet installations Differential, CAN_H and CAN_L quickly ANALOG SAMPLE RATE: SIGNAL ERROR THRESHOLD: TWO OPERATIONAL MODES OF USE BUS LOAD MEASUREMENT: BUS MESSAGE RATE MEASUREMENT: Electrician Mode (simple) ERROR RATE MEASUREMENT: Voltage and summarizes network 1.
