3.2.8. Preparing the Co-simulation of Simulink and Sysmac Studio You add the Sysmac Controller Interface block to the Simulink model and make the setting for data exchange between Simulink and Sysmac Studio. Also, you add the Sysmac IO Device block to link with the parameter settings of the Servo Drive in the Sysmac Studio project. 36 1 Open the Sample File No. 1 PLCCoderDemoMC.mdl that is provided separately on the Simulink. 2 Select the Sysmac Controller Interface block from the Simulink Library Browser and add it to the Simulink model that you opened in Step 1.
