EOL - DeviceNet / CAN Diagnostic Tool
Product phased out. Please call systerra for replacement options.

BradCommunications™ NetDoctor™ is a passive device that continuously monitors a DeviceNet or CAN network and sends the information over Ethernet to a PLC or PC monitoring system. The information can be accessed through a DLL interface, read directly by an EtherNet/IP™ master or served through OPC tags.

NetDoctor provides extremely accurate measurements of the network parameters using high-speed sampling. By storing a baseline measurement of a “good” network, it can predict imminent failures on individual devices. Device 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 replace the device prior to its causing any downtime.

etDoctor 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 NetDoctor is capable of streaming waveforms in advanced mode as a remote oscilloscope. 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.
