Interrupt Assignment Of The Slots For Expansion Cards On The Backplane - Siemens SIMATIC IPC847E Operating Instructions Manual

A.3.2

Interrupt assignment of the slots for expansion cards on the backplane

Note
All system resources (hardware addresses, memory allocation, interrupt allocation, DMA
channels) are dynamically assigned by the firmware or the operating system based on the
hardware equipment, drivers, installed expansion cards and connected external devices.
The assignment is made automatically and depends on the requested resources of the
connected devices and installed components. Due to this configuration dependency, clear
statements can only be made by determining them in relation to the system in the final
configuration.
The resources can be viewed in Windows as follows:
1. Press the "Windows® key" and "R" simultaneously.
2. Enter the "msinfo32" command in the "Open" field.
3. Click "OK" to confirm.
Variant 1: 9 slots (2 x PEG / 7 x PCI)
You can find information about this bus board version under "Slots for expansion cards on
the bus board (Page 182)".
