The PCI expansion bus is a field installable backplane that you need when you configure an open controller system with any of the available option modules You install the PCI bus in a series B 1746 chassis You only need one PCI expansion bus per open controller chassis PCI Peripheral Component Interconnect is an industry standard that defines a high speed interface local bus that allows peripherals to connect to the same bus as the system memory The open controller PCI bus adheres to the electrical and logical standards of commercial desktop PCI and industrial passive bus CompactPCI The pin and socket connector on the open controller PCI bus is unique so that the expansion bus fits into the 1746 chassis The PCI bus provides a wide bandwidth to a limited number of peripherals as many as 5 option modules in an open controller system while the 1746 I O bus handles the I O functions These non proprietary well defined electrical and logical standards mean you can depend on the PCI bus to provide high speed data transfer rates e soft configuration of modules on the PCI bus plug and play support of modules on the PCI bus 1747 2 22 May 1997 When planning your open controller system make sure you select a PCI bus with enough slots you cannot place 1746 I O modules in PCI bus slots or open controller option modules in local 1746 I O bus slots functional specifications
