ProfiCore Ultra is the required hardware to use ProfiTrace2. It translates profibus to USB and vice versa. It has an isolated RS 485 interface and is equipped with a high-speed digital oscilloscope that is able to capture bus signals running at 12 Mbps. It can also be used on profibus PA installations with the PA Probe Ultra. The ProfiTrace2 software that runs on the ProfiCore is very user-friendly and easy to use. Next to the message recorder, search and trigger menus, it has lots of powerful features such as: Live List and statistics The Live List is a matrix that lists all the available devices. It is directly visible which devices are ‘troublemakers’. With different background colours the status of the devices is displayed. The Live List can also generate the product name of the devices when a diagnostic message is captured (synchronised with the GSD library). The statistics matrix is the most decisive feature of the analyser. This field can really indicate how healthy the installation is. It displays all the important information that a user, especially a maintenance man, is really interested in: retry messages, fall-outs, cycle time, diagnostic messages, etc. The user does not have to inspect messages or do difficult operations to ensure the quality of the installation. Integrated oscilloscope The oscilloscope is used for the inspection of the signal quality. It runs immediately displaying all signals that are measured. The time base and voltage levels can easily be adjusted. By double-clicking on the devices in the Live List, the oscilloscope triggers on the respective device and only displays its signals. This is a perfect mode to inspect the signal quality for individual devices. By measuring the width of the reflections, the tool indicates the distance to the ‘problem’. A powerful feature of the oscilloscope is the Bit Interpretation Engine. It displays the bits that ProfiTrace detects on the bus. Bar graph The Bar graph illustrates an average amplitude level of the signals from all available devices. It is a helpful utility to get an overall signal quality of the network. The average signal amplitude should be around 5 V. When there are bus problems the Bar graph will display irregular voltage levels and the colour of the bars will change. Topology ProfiTrace2 has the capability to generate the topology of the profibus network without shutting down the installation! The Topology scan creates a clear network drawing that contains the location of the devices and length of the cable that links them. It is a simple procedure: connect ProfiTrace to the working installation and with just 3 mouse clicks, the topology is generated. DP-V0/V1 Master ProfiCaptain is a PROFIBUS DP-V0/DP-V1 class 1 and 2 master that has been designed for applications like: I/O tests, commissioning, parameterisation and demonstrations. It fills the gaps that other products leave open and makes working with profibus a lot easier, faster and more fun. The main platform is a configuration environment in which the user can setup his slaves with the respective modules and parameters. For this master there is also an API available for programmers who would like to develop their own master application (DLL). Reporting The reporting feature creates a detailed report that contains the electrical signals of all devices, their faults, the topology, bar graph and administrative information. On the front page it gives a conclusion if the installation is approved or not. It displays the information in an understandable way, contains all required elements and is very compact. Road ahead The opportunities are vast. You can display ProfiTrace tags in a SCADA/HMI package or link it to an SMS/email client and sent a message when something happens with the profibus or even generate your own report in MS word /Excel. ProfiTrace is without question the beacon for profibus troubleshooting and maintenance.
