Interrupt Assignment Of The Slot Connectors On The Bus Board - Siemens SIMATIC IPC847D Instructions De Service

IMPORTANT: Updated information for IPC847D

9.15 Interrupt assignment of the slot connectors on the bus board

9.15 Interrupt assignment of the slot connectors on the bus board
Changes and supplements to section 8.5.2.3 of the operating instructions.
Remarque
All system resources (hardware addresses, memory allocation, interrupt assignment, DMA
channels) are assigned dynamically by the BIOS or the Windows operating system,
depending on the hardware equipment, drivers, installed expansion cards and connected
external devices.
Assignment is automatic and depends on the demanded resources of the connected devices
and the inserted modules. Due to this configuration dependency, clear statements can only
be made by determining them in relation to the system in the final configuration. Resources
may be viewed as follows under Windows:
1. Press the "Windows key" and "R" simultaneously.
The "Run" dialog box opens.
2. Enter "msinfo32" in the "Open" field.
3. Confirm your entry with "OK".
The following tables 1, 2 and 3 are examples of assignments if the system is operated in PIC
mode (legacy mode).
The tables apply to the configuration with an expansion module which uses only one
interrupt, e.g. PCI module which uses the INTA# interrupt, connected to pin A6 of the PCI
bus connector.
