Port to the Bus Unit (X1)
The SIMATIC Box PC 620 has a bus unit with a PCI slot and a shared
ISA /PCI slot. Expansion cards can be installed to ISA specification (Rev. 3.1) and
PCI specification (Rev. 2.0) with a maximum length of 265mm (175 mm for shared
ISA/PCI modules). All the PCI slots can be used as masters. Only 5V PCI modules
are operable.
The bus unit is executed as a purely passive module, i.e. there are only socket
contacts for the expansion cards and any necessary backup capacitors. The power
supply to the expansion cards is effected via the connection of the bus unit with the
basic board. The -5V voltage is not provided for in the power supply and is
produced from the -12V on the bus unit via in–phase voltage control.
The connection to the basic board is effected by a gold-plated two-part connector
of the type ‘EISA’. All the necessary bus signals (ISA and PCI) are applied to this
connector. The following table shows the connector assignment.
