what is wrong here it is a normal CNR block with the value 1680 I place it outside the subsystem block directly on the output Extentons__xS51_1_AO1 I measure 4.2 volts I place the CNR block in the subsystem block it gives no output to the output Extentons__xS51_1_AO1
please, check the TagVisibility parameter of Goto flag - if it is set to "local" it is not visible to the MB driver. Also check the output of REXYGEN Compiler which will tell you details about wrong setup of flags.
