I have Diolan GPIO-24 adapter. I need to generate a PWM wave by using this device. I can't understand what commands do I need to use to set the high pulse period and low pulse period of PWM? Can anyone help?

By using GPIO24 adapter, You can generate a PWM wave. To configure pins for PWM use GPIO_SET_CFG command.
Also the GPIO_SET_PWM_CFG command is assigned to set configuration settings for generating the pwm wave.
PWM mode is configured by specifying the high time (T1) period and low time (T0) period in ms.
All available configurable pins can be set for PWM output in this adapter.

I see they have both PWM and HPWM. Do you know what is the difference?

The PWM (Low frequency pulse width modulation) is implemented in GPIO-24 Adapter firmware. The HPWM (High-frequency pulse width modulation) interface is based on the PWM module of the PIC18F4455 microcontroller. For more details read http://www.diolan.com/io/pwm.html as was mentioned by beenthere.
