For example, could you just send an error, output range, and gains to the motor controller and would it calculate the PID itself?

It means you can plug a sensor like an encoder or potentiometer into the speed controller, then, with CAN, you tell the speed controller you want to enable PID control and what your PID gains are, and it will do the PID control logic on the speed controller itself.
The advantage is that you don't have to waste cRIO processing power on PID loops and you can run them much faster. The disadvantage used to be that the only controller you could use for it, the Jaguar, was big, expensive, and not as reliable as the Victor.
