LABVIEW PROFIBUS DRIVER

Process GSD device description files and maintain a hardware catalog of devices to be configured on the bus Allow the PROFIBUS device address to be specified Allow the specification of the input and output data to be transferred between master and slave Allow certain startup parameters to be selected to activate specific operating modes or features of the device Allow selection of the system baud rate Generate the database file so it can be used by the master At the same time a vendor develops a slave device, it must develop a device description GSD file. The standard diagnostics six bytes that every slave device is required to report contain information that is generally related to startup problems. The exact formats of these different diagnostic information blocks are presented in Appendix A. Module-related diagnostics are used to report diagnostics for a modular slave, which is a slave that consists of an “intelligent” head module plus plug-in modules. When the last master in the “logical token ring” has gone through its data exchange cycle, it passes control back to the first master, and the overall operation starts again.

This makes it very easy to diagnose the problem right down to the wire level. The higher the baud rate and the proibus the cable, the more important termination becomes. Are you looking for order or quoting information?

Therefore, you must check the device’s documentation to determine the exact format. Our three- or five-year service programs for hardware and systems provide the coverage you need while ensuring lowest profibs cost of ownership over the life of your system: Labvuew the transmission speed is 1. This step downloads the network configuration to the master. Termination prevents reflections that can disturb the data communication. When the devices are very close together, there is a large chance that reflections in the data communication small short circuits can be caused by the input capacitance.

All of the information that the master must know to start up the bus comes from a configuration database file that is generated by a PROFIBUS configuration tool. No exchange with DP Master see manual for possible reasons. You specify which proffibus devices the master should find on the bus as well as which information should be transferred from labvie master to each slave during this startup phase.

This often slips in when you are using a lot of fiber-optic cable and there is only a short length of copper cable in the cabinets.

The Configuration tab shows the supported slave modules. You can now load this configuration database into the master device. Back to Top 6.

NI equips engineers and scientists with systems that accelerate productivity, innovation, and discovery. A device can use this format to report that an individual channel of a specific module has a problem, for example, short circuit, wire break, overvoltage, and so on. To find training courses for your hardware, visit ni. At NI, we produce high-performance hardware and are committed to helping profubus maintain that performance for years to come.

Device and System Startup You specify which slave devices the master should find on the bus as well as which information should be transferred from the master to each slave during this startup phase.

PROFIBUS Overview

This format gives the head module the capability to report that a particular plug-in module has a diagnostic. When dropping the Express VI to the block diagram, a dialog opens to configure the slave device. Gain the skills you need to design and develop high-quality applications: Included graphical networking Configurator software Supported services: Scanning not activated Slave Mode: Select the slave icon, and then click and drag the appropriate memory configuration to slot 0 in the configuration project on the lower right.

Module-related diagnostics are used to report diagnostics for a modular slave, which is a slave that consists of an “intelligent” head module plus plug-in modules.
