Installation of the PCI driver
After installation of the SERCOS card, Windows 2000, for example, comes up with the following message during
start-up:
The PCI driver for the SERCOS card is supplied with the Beckhoff TwinCAT automation software.
Follow the instructions of the Add Hardware Wizard.
Under Windows XP, the PCI driver is installed in the same way.
Under Windows NT 4.0, the PCI driver is not required.
Example for the resources of an FC750x under Windows2000.
(Control Panel / System / Hardware / Device Manager / TwinCAT PNP drivers / TwinCAT FC750x PCI driver /
Resources):
Note
The PCI bus allocates an IRQ for the SERCOS card (IRQ9 in the example), although
the IRQ is not used by the SERCOS card!
