DF Profinet IO PCIe Kunbus Interface Card

The Kunbus DF Profinet IO PCIe Interface Card operates as a PROFINET IO controller and/or as PROFINET IO device. Because its efficiency is so huge the interface card achieves as PN IO controller operations of 64 PROFINET devices per millisecond in the Conformance Class B. A second independent Ethernet interface allows the module to be used simultaneously as a PROFINET IO device. A stand-alone operation, such as PN IO device is also possible. In PN IO controller mode, among the cyclic data traffic, all acyclic read/write/diagnosis and alarm functions are supported and of course compatible to the PN IO standard of PROFIBUS and PROFINET International. The size of the process image of the card's I/O data is 16 Kbyte (8 Kbyte input and 8 Kbyte output data). The PROFINET configuration data is stored in a failsafe flash type memory.

The controller board also supports PROFINET supervisor functionality, making it possible to scan the network as well as to control the names and IP addresses of various PROFINET devices. The CONFIGURATOR III is available for compilation and download of the PROFINET configuration. The comfortable and fully graphical tool minimizes the configuration effort, while extensive download, analysis and control functions permit an efficient checkup of the configured PROFINET IO network.

In PN IO device mode the min. cycle time is 1 millisecond with a max. IO data size of 1440 bytes. The board does not need to be configured but instead receives the IO configuration directly from the PN IO controller, which significantly simplifies putting it into service. A special feature supported by the board is the PN IO shared device mode, which allows multiple PN IO controllers (up to 20) to access allocated IO buffers within the device simultaneously. This allows a very flexible integration also into large and complex PN IO networks. The operation modes PN IO controller and PN IO device can be run simultaneously.
