A first-class PC analyser for active as well as passive PROFINET diagnostics (analyses stations and communication). It supports comprehensive network analysis, report generation and multiple languages including Czech. It is the ideal tool for anyone who works with PROFINET. At an unbeatable price it offers unique insight into the health of your PROFINET network.
The PNT – PROFINET Tool is a top quality software analyser for PROFINET networks and communication. It provides you with all essential information about the health of your PROFINET network. At an unbeatable price you will get a program that enables you to gain deep insight into the health of your PROFINET network, carries out automatic network diagnostics, warns you about all problems on the network and provides comprehensive diagnostic reports in multiple languages.
It supports active diagnostics – the so-called free port diagnostics (you connect your PC to any free port in your PROFINET network via Ethernet cable). It also supports passive analysis, through several different methods. In many cases, the following methods are sufficient – passive analysis via a mirror port on a switch or the most frequently used TAP adapters on the market.
The program comes with a hardware key that enables you to install the software on any number of computers. Although your PROFINET network can be analysed using only the computer that the hardware key is plugged into, diagnostics results can also be viewed offline on computers without the key.
The program supports multiple languages and enables you to switch between them while it is running. It is currently the only software for comprehensive PROFINET communication diagnostics that supports Czech. Results from each analysis performed can be saved to a PDF file. In the active analysis mode, the program can compare results from the analyses performed. You will find this useful when you need to identify the differences between the latest analysis performed and an analysis carried out before the latest one (e.g. to identify an increase in the number of corrupted packets).
How to use the PNT – PROFINET Tool to carry out PROFINET diagnostics?
To obtain deep insight into the health of your network, you have to perform two different types of analysis. Each provides you with different information about your network and is carried out in a different way.
ACTIVE ANALYSIS VIA FREE PORT
The PNT – PROFINET Tool actively requests data from all PROFINET devices in the network that is being analysed. To perform active analysis, you need:
Any free port in the PROFINET network
An Ethernet cable for connecting your computer with the PNT – PROFINET Tool program installed
PASSIVE ANALYSIS VIA MIRROR PORT OR TAP ADAPTER
Typically installed directly behind the IO controller, passive analysis allows you to capture all communication on your PROFINET network. Passive diagnostics can be performed in two different ways, through:
A mirror port on a PROFINET switch (with an accuracy of 80% – which is sufficient if you would like to gain a basic insight into your network's health)
The TAP adapter, installed directly behind the IO controller (with an accuracy of 100%)
To obtain a basic insight into the health of your network, we recommend performing active analysis and passive analysis via mirror port. One of the advantages is that you do not have to shut down or disconnect your network. To carry out the more accurate passive analysis, i.e. passive analysis via TAP adapter, you often have to disconnect the PROFINET cable and install a TAP adapter. This is not always possible. The TAP adapter installs on to the cable with the most traffic, typically between the PLC and the next network node (either a swich or another PROFINET device).
What information about your PROFINET network will the PNT – PROFINET Tool provide?
A LIST OF PROFINET STATIONS
A list of PROFINET stations on the network including their names, IP addresses, MAC addresses, subnet masks, types, etc. You can rewrite the name and IP address of any IO-Device, quickly identify a specific device by flashing its LEDs, identify a device's neighbouring station(s), and more.
A list of non-PROFINET stations on the network including their IP addresses, MAC addresses and manufacturers' names.
A list of all PROFINET stations on the network and their neighbouring stations (stations must support the LLDP and SNMP protocols), a graphical layout showing the stations connected to each station, plus a general graphical layout of the entire PROFINET topology.
ERRORS AND DATA TRAFFIC
Communication statistics for each station on the network (i.e. the number of packets for both ports, the number of corrupted and dropped packets, and uptime of a given station and PROFINET ports). In/out data traffic for each port (Mbps) including a colour warning when traffic exceeds 10/20/50 Mbps.
A list of PROFINET stations and their configuration, statuses and occupancy of slots/subslots, manufacturers' Product IDs, serial numbers, FW/HW versions, etc.
A CHECK ON A GIVEN DEVICE
An online check on a given device including data traffic on both ports (IN/OUT) and the number of IN/OUT packets/bytes
Through an Ethernet cable plugged into a free network port
Through an Ethernet cable plugged into a free port on the switch that the PLC (IO-Controller) is connected to. In the switch, set the PLC's port as monitored port and the PC's port as mirror port.
Through the TAP adapter, which you install between the PLC and the rest of the network.
LIVELIST – AN ONLINE LIST OF AVAILABLE STATIONS
A list of available stations including their statuses, failure statistics, filtering by station status, communication cycle and its update rate (ms), online PN alarm messages
Traffic load graph
A general graph that shows the total traffic load for the network, the load for PROFINET communication and the load for other communication (Mbit/s)
A list of all the alarms recorded on the PROFINET network including filtering by alarm type
Saving PROFINET messages to a file or saving them to a file using a message recording trigger – the file can be displayed as a graph or opened in Wireshark.
STATION COMMUNICATION CYCLE & JITTER (OFF-LINE)
The PNT – PROFINET Tool enables you to create a table with all stations, showing stations' communication cycles, jitter (requires analysis via TAP adapter), data traffic, minimum and maximum values, etc.
PNT – PROFINET Tool
Installation file for the PROFINET software analyser. Enables full installation. The program itself can be used for viewing records offline. For analysis, the USB licence is required.
