Description

Device Driver for Linux

A Device Driver is required for the communication between the Communication Interface and the PC applications under the Linux operating system. The driver contains the complete management of the interface and has a simple interface.

The user is responsible only for the transfer of the correct parameters to the Device Driver. All dependencies on the operating system such as interrupt management and time monitoring are carried out by the driver. Therefore, the user interface is independent of the operating system. The driver works together with all our Communication Interfaces and comprises all functions for initialising, parameterising, exchange of data and retrieval of status information. The driver works in Polling or Interrupt operation and services a maximum of four cards in one PC. However, the card can be utilised as ISA, PCI or PC/104. The functions of the Device Driver are independent of the fieldbus system. The access to the variables in the process image is fully identical. What is different are the parameters of the diagnostic and status structures, as well as fieldbus-specific commands. Associated definitions are included as header files.

The driver is supplied together with the setup program and test program in source code. This makes the first time use easy.

The driver works together with all of our communication interfaces and comprises all of the functions for initializing, parameterizing, exchanging data and retrieving status information. The driver works in polling or interrupt mode and services a maximum of four cards in one PC. However, the card can be utilized as ISA, PCI or PCMCIA or a combination as desired. The functions of the device driver are independent of the fieldbus system. The access to the variables in the process image is fully identical. What is different are the parameters of the diagnostic and status structures, as well as fieldbus-specific commands. Associated definitions are included as header files. By taking these corresponding facts into account, it is possible to interchange PC cards from different fieldbus systems without this resulting in any alterations in the application. Demo programs in source code are included with the driver and thus permit quick and easy familiarization. Further components include an installation program which carries out the entire registration on the operating system.
