When will come to PCAN-USB CAN analyser driver support?

Is it possible to use Frequency input to get the engine speed by using the W contact of the alternator?

I have a system that includes a dc motor, a dc motor controller, an MD3 master and XA2 expansion modules.

My overall objective is to control the output speed of the motor, through the motor controller, via closed loop PID control with the MD3 and one of the XA2 modules. The motor controller can accept a 0-10Vdc signal to regulate the speed of the motor.

Assuming I can monitor the rotation speed of the motor's output shaft via a frequency input or voltage input into the XA2 module but am uncertain of how I can output the 0-10Vdc output signal to the motor controller from the XA2 module, any ideas?

Thanks, much appreciated.
