Checking Resources before Installation

Check the following items before starting to set up or install the SYSMAC CS1
Board.
Note The SYSMAC CS1 Board is a Plug and Play compatible PCI Board.
Item to check
Available PCI Slot
IRQ conflict
Note 1. The CS1PC-PCI01-DRM and its battery are packed separately, so refer to
the CS Series Programmable Controllers Operation Manual (W339) for de-
tails and perform the following procedure:
• Install the battery. (Refer to Appendix A Replacing the Battery for details.)
• Clear the memory (all clear.)
• Clear all error messages.
• Set the clock if the clock function is being used.
2. I/O words are allocated to I/O Units based on the I/O Units that are actually
mounted in the PLC, so it is necessary to create an I/O table.
3. Refer to your computer's User's Guide for details on accessing the BIOS
menu and changing BIOS settings.
4. Use the following procedure to determine which IRQ number is being used
by an ISA device.
• Start up the computer without the SYSMAC CS1 Board installed.
• Select Start/Settings/Control Panel from the Start menu. Double-click
the System icon and click the Device Manager tab.
• Double-click the desired ISA board to display its properties. Click Re-
sources to list the resources being used by the ISA board and check the
board's Interrupt Request setting.
Explanation
Check that the computer has an open PCI slot.
This Board uses an IRQ (interrupt request). An IRQ is
automatically assigned to the PCI bus, but the IRQ may
already be in use by the ISA bus in a computer with an ISA
bus. The computer may not boot properly if there is an IRQ
conflict between the PCI bus and ISA bus. Use one of the
following methods to avoid allocation of an IRQ that is being
used by the ISA bus.
• Open the computer's BIOS menu and disable Plug and Play
operation.
• Open the computer's BIOS menu and set any IRQs that are
being used by ISA devices to "Reserved" in the PCI bus' IRQ
allocation settings.
