S7-400, M7-400 Programmable Controllers Module Specifications
A5E00069467-07

The interface submodule supplies an interrupt request (IRQa and IRQb) for each
serial port.

You can define the assignment of the interrupt requests IRQa and IRQb to the
appropriate processor interrupt requests in the BIOS Setup.

Table 13-14

Interrupt Assignments of the IF 962-COM Interface Submodule

COM a

IRQ a

Can be set in the BIOS

COM b

IRQ b

Can be set in the BIOS
setup

Default settings in the BIOS are: IRQ 4 for COM1 and IRQ3 for COM2.

The IF 962-COM interface submodule has the submodule ID 41

.

The IF 962-COM interface submodule receives its supply voltage from the M7-400
programmable modules or from the M7-300/400 expansion modules. The current
consumption given in the technical specifications is the consumption required for
dimensioning the power supply, that is, the current consumption is referenced to
24 V in the M7-300 and to 5 V in the M7-400.
