Simulink real time freeze with Beckhoff modules

I’m working with Beckhoff modules in combination with Simulink real time. At the moment my stack is a follows: - EK1100 - 3xEL3102 - EL3104 - 2xEL4132 - EL1124 This all works fine with the Simulink real time software. However if I now connect any other card (for example another EL4132) the real time execution freezes after approximately 0.1s on the target pc. Obviously I have generated different config files for the different setups. The average time of execution is way smaller than the sample time (0.001s). Even if I increase the sample time to 0.01s, the application still freezes on the target pc.

I have also tried not connecting the Beckhoff modules with the config file loaded in Simulink. The application runs fine then, however, of course without any input and output. Could you provide support with this problem?
