PROFIBUS Troubleshooting Tool Demonstration

his is a brief tutorial on how to operate the Procentec PROFIBUS Troubleshooting Toolkit Ultra Plus. For this tutorial, the PROFIBUS Troubleshooting Toolkit Ultra Plus is used. The PROFIBUS Training Kit will also be utilized; this is used for our troubleshooting and maintenance training using the ProfiTrace tools. In the PROFIBUS Training Kit, there is a PLC in the bottom of the case as well as five devices in the inner lid of the case. The last thing we will use is a Windows PC that is running ProfiTrace software.

PROFIBUS Troubleshooting Tool Demonstration: Topology (29:05)

The last part that is included in the troubleshooting kit Ultra Plus is the tab called “Topology,” which is located directly to the right of the bar graph tab. This can be used to calculate the topology, which is basically a drawing of the instillation. It tells the user who is connected to who in this daisy chain of PROFIBUS cables. When starting this up, it is important that the user selects where on the bus they are connected. In this case, we plugged the ProfiCore Ultra onto the PG connector on the PLC/master. So on the drop down menu, we would select master.

PROFIBUS Troubleshooting Tool Demonstration: Bar Graph (26:55)

The next thing we will take a look at is the “Bar graph” tab, which is directly to the right of the ScopeWare one. The bar graph is measuring the amplitude of the signal coming from each device. On the graph, there is the signal and address on the far left in which the ProfiCore Ultra is connected to in order for it to be the strongest. Devices further away have a little bit less strength in signal.

PROFIBUS Troubleshooting Tool Demonstration: ScopeWare (19:30)

Most problems in PROFIBUS are caused by physical layer problems. This essentially means there are cabling issues such as terminating resistors, shielding, rounding, and EMC. Things like this can cause problems with the high speed data communication cable, which is the PROFIBUS cable. One of the important tools in this program is called “ScopeWare,” which can be accessed on the upper left corner of the screen directly to the right of the ProfiTrace tab.

PROFIBUS Troubleshooting Tool Demonstration: Checking Device Statistics (11:40)

When looking at the live list on the main screen, the user is able to see real time updates of what is going on. If the user had just walked up to the instillation and saw that all of the devices are green, they would assume that there is nothing wrong with the instillation. In reality, they would be seeing a real time representation of what is going on right now.

PROFIBUS Troubleshooting Tool Demonstration: Using ProfiTrace Software (3:28)

For now, stay on the main ProfiTrace page that is included in every kit that Grid Connect sells. To begin, click on the button that says “Init ProfiCore Ultra.” It will begin to initialize the ProfiCore Ultra, essentially it is checking the firmware that is loaded in the Ultra to make sure it is the latest firmware. Then it will begin to check the baudrate of the instillation. Once this is complete, there will be five boxes within the main matrix (grid) on the screen.
