Monitor Devicenet, Predict Failures

The DeviceNet Doctor provides extremely accurate measurements of the network parameters using high-speed sampling, says the vendor. By storing a baseline measurement of a "good" network, it can predict imminent failures on individual devices. Device measurements can then be set so 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. Data can also be stored to historian software for future analysis.
