INTERBUS COMMUNICATIN PROBLEM

[irb]

Hi
We have been trying to solve our problem with Pneumatic Spot Welding Robot.
We have got PSS 5000 Bosch Timer and 2 items IBS IP CDIO/R 24-8/SF.My question about the INTERBUS connection between Bosch Timer and CDIO modules. We need small explanation about the connections. First of all we have connected DSQC 344 to Bosch Timer's in port  and Bosch Timer's Out port to CDIO/R. ( Is it true ? or  should we connect to DSQC 344 SL RB out port ?  ) We have already prepared EIO.cfg file three of them..But DSQC 344 didn’t communicate with  IBS IP CDIO/R/24-8/SF modules.Normally robot recognize Bosch Timer properly but when we add a IBS IP CDIO/R 24-8/SF it creates problems.. 
We aren't sure that neither true connection has been made or not. ( Bosch Timer out port or DSQC 344 SL RSB Out port )   Is there any circuit diagram about this issue ?
