The BradCommunications NetDoctorTM is a passive device that continuously monitors a DeviceNet or CAN network and stores the information as OPC status tags on an HMI display over Ethernet. Users can also access the information through a DLL interface, or an EtherNet/IPTM master can read it directly.
The NetDoctor accurately measures network parameters using high-speed sampling. By storing a baseline measurement of a good network, it predicts imminent failures on individual devices. When NetDoctor analyzes an OPC status tag and discovers that it is outside the acceptable limits, operators can replace the device before it causes downtime.
