E+ and simulink - BCVTB

[Yeo Wei jie]

Hi, i am incorporating E+ and simulink together on bcvtb to control a FCU unit to achieve the desired setpoint temperature. So i created an On/Off controller in Simulink and i am feedbacking room and setpoint temperature from E+ to simulink in BCVTB. However i encountered an error in simulink which is the incorrect port width/dimensions.

The error is as follows:

Error using simulateAndExit (line 2)

    Error in port widths or dimensions. Output port 1 of 'controllertest3/controller/TSetPoi/Cooling Setpoint ' is a one dimensional vector with 512 elements.

    Error using simulateAndExit (line 2)

    Error in port widths or dimensions. Input port 1 of 'controllertest3/controller/TSetPoi/Sum' is a one dimensional vector with 1 elements.

It says that the output port and the input port which is essentially the same block has different elements, however my dimensions are all set to inherit.

 Any help is appreciated.
