FM 456-2 Application Function Module Installation, Hardware, and Startup
C79000-G7076-C458-01
Interconnecting the Modules
Take the application function module and first expansion module, position them on
a level surface (see Figure 2-6) and press them carefully together so that all pins
of the expansion module plug are precisely inserted into the socket on the
FM 456-2.
Then plug the other modules successively in to the assembled group (see
Figure 2-6). All the expansion modules are then connected to the ISA bus of the
application function module.

Note
Only particular combinations of the expansion modules are allowed. See the chap-
ter on M7-400 expansion in
manual /1/, section “Permissible Combinations”.
Note
The connector pins can be damaged.
If the modules are not exactly lined up for interconnecting, the pins can be
damaged. Line up the modules precisely when interconnecting.
