Fieldbus and Industrial Ethernet Monitoring

Essential Tools: Diagnostics and Maintenance of Industrial Networks and Fieldbuses

To maintain an industrial network in optimal condition and minimize downtime on a production line, it is essential to have the right tools. These tools can detect network anomalies and alert you to potential problems before they occur. This provides the time needed to take appropriate action and prevent a machine from being inactive for several days.

Problems on a production line are common due to wear and tear on machines and devices as a result of use, vibrations, temperature fluctuations, among other factors. Optimizing the maintenance of this equipment significantly contributes to improved production by reducing machine downtime.

Becolve Digital has specialized tools for the analysis, diagnosis, and implementation of industrial networks. These tools provide essential information about the network status, allowing you to confirm its condition. They also provide a step-by-step guide to network configuration, which is especially useful when migrating from a fieldbus protocol like PROFIBUS to an industrial network like PROFINET or Ethernet/IP. Each communication protocol has its own set of specific rules for optimal operation. It is crucial to know these rules in advance to avoid costly future problems in both network communication and the devices participating in it. These tools help to apply the specific rules for each network.

Thus, these diagnostic and monitoring tools allow, among other functions:

• Identify problems with missing end-of-line resistors.
• Determine the maximum cable length.
• Establish the maximum number of nodes allowed.
• Detect discontinuities in the bus.
• Perform topology scans.
• Capture faults and errors.

They also include functions such as triggers for data capture, graphical representation of information, and a protocol stack that facilitates problem identification by the user.

They can be fixed equipment: remaining in a cabinet for continuous data capture. But they can also be portable: which is useful in networks that do not have permanent diagnostic tools. Whether for an audit or to address a failure in the industrial network, both types of tools serve a specific purpose.

The benefits of having a fixed monitoring device

1. Sporadic Fault Capture: Captures faults that occur intermittently, making it easier to identify and resolve them before they become serious problems.
2. Device Status Monitoring: Allows constant monitoring of the status of devices on the network, providing the ability to analyze potential problems in real time and take preventive measures.
3. Device Usage Report Generation: The tool provides valuable data that can be used to develop detailed reports on device usage, which is essential for efficient network management.
4. Preventive Maintenance Planning: By having real-time information on the status of devices, it is possible to plan the maintenance of machines and devices before they present a failure. This significantly reduces production line downtime.

In summary, a fixed monitoring tool on the network offers a series of advantages that converge on a key objective: reducing production line downtime.

Mobile devices offer the flexibility to take them to any facility, allowing you to conveniently verify the status of the network. They provide a diagnosis of potential errors in the network or problems arising from non-compliance with protocol standards. Like fixed equipment, they offer a clear and simple interface along with potential solutions to address the detected problems.

The functionalities of these portable devices include the detection and diagnosis of:

1. Wiring Problems:
   Identification of faults in the integrity of the wiring that could affect network communication.
2. Duplicate Nodes:
   Locating duplicate nodes that can cause conflicts in the network.
3. Network Load:
   Evaluation of the current network load to ensure efficient operation.
4. End-of-Line Resistor Problems:
   Detection of problems related to end-of-line resistors, essential for the correct operation of the network.
5. Discontinuity in a Bus:
   Identification of discontinuities in the network bus that can interrupt communication.

Portable monitoring and diagnostic devices are indispensable allies for maintenance and diagnostic professionals: they allow a quick response to network challenges in real time, regardless of location.
