Memory Address Assignments - Siemens SIMATIC HMI IPC677C Operating Instructions Manual

Detailed descriptions
16.3 System resources
Exclusive interrupt in PIC mode
The interrupts are automatically assigned to the slots at system startup due to the default
settings in system BIOS.
Several slots may share the same interrupt, depending on the system configuration. This
functionality is known as interrupt sharing. Exclusive interrupts are not available in PIC
mode. Disable specific system resources in order to obtain exclusive interrupts. BIOS
assigns the PIC interrupts at random during restart of the system.
