I am setting up a Simulink model that contains a control algorithm to run in real-time on a Real-Time Target (converted desktop PC). Basically the application is I am trying to control an actuator position using a motor. I provide the commanded position, and feedback includes current motor velocity, and current actuator position. The model returns the current value that is supplied to the motor driver.
I am using Simulation Interface Toolkit for this effort. I have gone through all the steps to convert the model into a model DLL. I am now at the step to create a driver vi to map the hardware I/O to the model I/O. I have the following model I/O requirements
1 Feedback motor velocity
1 Setpoint Actuator position
1 Feedback Actuator position
1 Output current to motor driver
I was hoping to use an encoder for the Feedback Actuator position but it seems like this is not easy to configure in SIT as compared to Analog I/O and Digital I/O. My question is, is it possible to map a counter? Do I have to create a custom driver.vi?

Thanks for your reply.
I have across the article that you linked. I did not want to resort to that effort as it looks more time consuming than going through the dialog. I have SIT 5.0.0 currently installed. I don't think this is possible in 5.0.0 but I haven't fully tried yet. I was planning on creating a simple model in simulink that takes in one input and adds a constant value to it and then sends this result as an output. Of course I should be able to compile this simple model into a dll and then I will try creating a driver vi for it to see what options I am provided in the Hardware I/O dialog box.
I still have to ask, how can I upgrade to 5.0.1?
