LabVIEW PID controlled PWM output

Dear All,

I need to control the heater with set temperature. My idea is to use PID control which can output duty cycle percentage and in-turn generate the PWM signal to control the SSR using single board RIO with 1 KHz frequency.

I have searched the forum for previous post. But unfortunate to find right one, most of them uses DAQ to generate variable duty cycle PWM output. Hence am using RIO digital I/O line in RT, am not familiar on how to proceed.

I would be happy to see the replies.
