Warnings for loading TestDrive model with non-present modules

In OP6000 TestDrive chassis the synchronization is made by the last module present in the chassis. But a controller must refer to this last module in the Simulink model. If this is not the case, the synchronization fails, and watchdog makes the model reset. On the other hand if a module which is not in last position is present in the TD, the model will also reset. The typical error message is as follow : 

ERROR:   BM_Ctrl.c            : OpCtrl Base Module: Packet drift error GlobalNbRR=0 GlobalNbWR=3

Finally you must make a match between modules in your model and modules physically plugged into the chassis.

Example : I have in my simulink model a Base Module (BM), a Pulse Output Module (POM) and a Pulse Driven Load Module (PDL). My Configuration in the chassis must be BM-POM-PDL

• if I have BM-POM-PDL-RPG for example : the model resets just after load
• If I have BM-RPG-POM-PDL, for example : the model resets just after load
