What NetDoctor Does
NetDoctor is a passive device designed to continuously monitor DeviceNet or CAN networks. It sends the monitored information over Ethernet to a PLC (Programmable Logic Controller) or a PC-based monitoring system. This tool is essential for maintaining and diagnosing industrial networks.
Key Features and Functionality
Continuous Monitoring
NetDoctor continuously monitors the network in a passive state, ensuring it does not interfere with the normal operation of the network.
High-Speed Sampling
It uses high-speed sampling to measure network parameters, providing extremely accurate values by sampling the DeviceNet signal millions of times per second.
Data Access and Integration
The data collected by NetDoctor can be accessed through various methods, including:
- EtherNet/IP™ slave
- DLL interface
- Add-on OPC server
This allows for seamless integration with existing monitoring systems.
Advanced Diagnostics
NetDoctor can diagnose current faults on a non-functioning network by measuring hundreds of network parameters. It can pinpoint the node or location of the fault, minimizing downtime. Additionally, it can stream waveforms in advanced mode, acting as a remote oscilloscope.
Historical Data Analysis
The data captured by NetDoctor can be stored in historian software for future analysis. This is particularly useful for companies involved in batching applications, such as pharmaceutical and food & beverage industries, to analyze and prevent re-occurrences of network problems.
Configuration and Alerts
The tool allows for setting up status and alarm flags to indicate when a value has exceeded a set tolerance. Configuration software defines the values viewed through the monitor utility software.
Installation and Logging
NetDoctor features an ergonomic design with DIN rail or panel mount options and includes a USB port for logging information to a file in locations where Ethernet is not available.
Conclusion
In summary, NetDoctor is a powerful diagnostic tool that enhances network monitoring, provides accurate measurements, and supports advanced diagnostics and historical data analysis, making it an invaluable asset for maintaining and optimizing industrial networks.
