El EtherTAP – Te permite hacer un análisis profundo de tu red Profinet. Se debe colocar entre tu PLC maestro y el primer switch a manera de poder “ver” todo el tráfico de información del PLC y la red.

Al seleccionar la funcion EtherTap en el Dashboard de Osiris (Instalados en Mercury y Atlas) puedes ver:

Tiempo de Ciclo por Dispositivo
Cada dispositivo PROFINET envía y recibe información en su propio ciclo y aqui lo puedes identificar.

Jitter Positivo o Negativo
Jitter es la desviación de tiempo de un mensaje contra el tiempo de ciclo predefinido. Ejemplo: si un equipoenvía un mensaje cada 4ms, entonces un retraso de otros 4ms adicionales representa un jitter del 100% En el caso que el mensaje llegue 1ms antes de lo esperado, se reporta un jitter de 25%.

Numero de Paquetes perdidos
Los paquetes perdidos son aquellos que fallaron en el ciclo de la comunicación. Una red PROFINET saludable no deberia perder paquetes, por lo tanto si hay un número excesivo de paquetes perdidos la comunicación se puede detener.

Alarmas
Las Alarmas de PROFINET son errores especificos que los controladores mandan para informar su estatus cuando algo anormal sucede.

Grabación de Mensajes

Con nuestro software y Ethertap en conjunto se pueden registrar los mensajes de la red (paquetes de Ethernet) cuando algo anda mal en la red. Se registran en formato .pcapng que te permite abrirlos en Wireshark y otros software compatibles.
Se utilizan tres condiciones para activar el grabado automático:

• Cuando hay una Alarma Profinet
• Cuando el Jitter es elevado
• Cuando se pierden paquetes Profinet

Analisis de Ethernet

En este apartado se pueden ver valores estadísticos de la red donde EtherTap está conectado. Aqui podemos ver porcentajes de carga y número de errores ocurriendo en la red.

Easy Troubleshooting, Maintenance and Monitoring

The PROCENTEC Mercury is a robust tablet which features our new cross platform software package. This device is perfect for troubleshooting, maintenance and monitoring Industrial Ethernet and PROFIBUS networks, through in-the-field-use of our software. The PROCENTEC Mercury enables you to gain insight into the health and possible faults in your industrial network. While developing this innovative product, the user was, and remains, the main focus. This means the PROCENTEC Mercury offers an easy to use interface, remote and wireless connection, and mobility anywhere and anyplace.

Combining the power of the PROCENTEC product portfolio

The PROCENTEC Mercury is based on the same software as the PROCENTEC Atlas for Industrial Ethernet diagnostics and therefore offers the same Ease-of-Use and intuitive user interface. When combining the PROCENTEC Mercury with PROCENTEC ProfiTrace, it offers a new software package for troubleshooting PROFIBUS networks. Additionally, it also ties in with ComBricks Head Stations, providing detailed information about the attached PROFIBUS networks. The advantage of this is that facilities working in a mixed architecture or transitioning from PROFIBUS to Industrial Ethernet have all network information available in one, easy to understand overview.

Industrial Ethernet Diagnostics

When the PROCENTEC Mercury is plugged into an Industrial Ethernet network, it creates a clear overview of all devices and how they are connected in the network, such as the topology. This topology can be viewed in the galaxy view, hierarchic tree view and the customizable view where you can easily create your own personal view snapping the nodes to the underlying grid. This customized view can be saved and exported, which means it can also be utilized easily at different locations with the same set-up. Significant information about a device or connection will appear in the topology by clicking on it. This data is displayed with clear NAMUR NE 107 icons identifying where problems are occurring in the network. A device list and alarm list that can be exported as CSV files, make it easier to document or further analysis of the network.

Collecting information about the quality of the network is important, but very complicated in most tools. The PROCENTEC Mercury provides this information in an easy way through the Q-Factor (Quality Factor). This feature can be found on the dashboard and works with a weighted algorithm to score the quality of the network. The Q-Factor can be shown in different ways; from 0 to 5000, according to the automotive standard, or from 0 to 100% as a relative display of the quality of the network. A simpler overview can also be provided through the traffic light feature, which can show the status in three colors.

PROFIBUS Diagnostics

When the PROCENTEC Mercury is plugged into a PROFIBUS network, it works with the same software as our ProfiTrace toolkits in order to analyze the network. The PROCENTEC Mercury is very easy to use and it combines all required elements to detect PROFIBUS faults. Typical PROFIBUS failures such as noise, reflections, voltage drops, termination problems, double addresses, wire breaks and configuration faults are quickly identified. By being able to identify faults quicker, they are usually also resolved quicker, which leads to minimization of expensive downtime in your installation.

Similar with Industrial Ethernet, collecting information about a PROFIBUS network is crucial. To collect this information, the ProfiCore, which is part of our ProfiTrace, is used. Customers who already own a ProfiCore can use it with the PROCENTEC Mercury as well. With the built-in oscilloscope, noise, reflections, and termination problems can be detected. Messages can be recorded and a Live List continuously shows all the available devices. Additionally, a network condition indicator shows the condition of the installation, without doing any difficult tasks.
