Hi, i am trying to incorporate E+ together with simulink to create a PID controller to achieve the setpoint temperature in a room by controlling the water flow rate. Firstly i made my model in E+ and run it and it was fine. Following that, i inserted the externalinterface parameters: Externalinterface: PtolemyServer Externalinterface - schedule: TsetCoo; Any number; 22;
When i run it in BCVTB, i have the following simulation log:
