Accepting Edited Values
Only the values for which the relevant interface submodule has been designed are
accepted by the system in the edit boxes. If, for example, you enter three values
under “Interrupt Source” and the interface submodule only has one interrupt, only
the first value will be significant.
Any changed values are only saved when you confirm them with the TAB key or
with SHIFT –TAB (only locally, not under Remote Setup).
Select Submodule Number
Here, you enter the consecutive number for the submodule receptacle containing
the interface submodule or you select the number using the cursor control keys
↑↓ .
In the M7-400, you can enter submodule receptacle numbers 0 to 14 if the
maximum possible three EXM 478 expansion modules are in use (see
Section 12.2) Three submodule receptacle numbers are used per slot on the
backplane bus.
The submodule receptacle number is linked to the other values on this setup page.
If you change the submodule receptacle number, the associated values also
appear, if they have been entered.
I/O Base (Gray Type)
Shows the current address of the expansion module (see Chapter 12 “M7-400
Expansions”) or CPU associated with the submodule receptacle. However, the
double-width CPU has two addresses, one address for submodule receptacles in
its left half and a second address, higher by + 100H for the submodule receptacle
in its right half. The information cannot be edited.
Type Configured + Detected (Gray Type)
At “Type configured,” you enter the type of interface submodule already plugged
into this slot or still to be plugged in.
“Detected” indicates the type of interface submodule currently (at the last CPU
power up) occupying this slot. The information cannot be edited.
The BIOS executes a SETPOINT/ACTUAL VALUE comparison. If the value set in
“Type configured” does not agree with the value in “detected”, or if the value 0FFH
has been configured in “Type configured”, the BIOS does not execute the
configuration for this interface submodule.
If there is no interface submodule in the submodule receptacle, the value “FF” is
displayed.
