The I/O modules are connected on the right-hand end of the bus
coupler, as with all Schleicher bus couplers (see also section
Expansion Modules from the RIO System).
Furthermore information see also operating manual RIO Bus Couplers
part no. 322 157 00.

6.1
Recognition of XRIO Configuration by XCx Operating System
The XCx operating system automatically recognizes the XRIO
configuration. If the current configuration differs from the previously
saved configuration automatic PLC start will not be carried out.
The XRIO configuration is saved on the compact flash:
when the XCx is first switched on
in the
\ata0\OS\PLC\sysconf.txt
configuration file and in the system
information
\ata0\OS\logfiles\sysinfo.txt
each subsequent time XCx is switched on
(as well as after
reset via the MULTIPROG project control dialog and when a new
project is created in MULTIPROG) only in system information
\ata0\OS\logfiles\sysinfo.txt.
(see The sysinfo.txt file).
The information on the current XRIO configuration from
the
\ata0\OS\logfiles\sysinfo.txt
file is important for the
I/O driver declaration in the PLC project.
If a difference between the configuration file and the actual XRIO
configuration is found when the XCx start up, no automatic start
will be carried out (XCx lockswitch set to WARM or COLD).
Manual start via the MULTIPROG project control dialog is,
however, possible.
Manual start of XCx with incorrect XRIO configuration
can cause unpredictable states in the I/O periphery.
Precautions must be taken to prevent harm to people
and equipment.
The XCx configuration file can be updated if required:
Enter value -1 in shared RAM location
cmpSwrdPlcRw_lWrtSysConf
. (After successful update value 100
will appear there.)
Alternatively you can also delete the configuration file.
Then switch the XCx off and on again, or set the lock switch to
PROG and initiate RESET on the XCx.
