Hi, is anyone familiar with the pulse width modulation output on the SIMATIC s7-300 series? I've set up the count module in HW Config, and want to use it to output a pulse with frequency between 0 and 2 000 Hz, but I'm not sure how to set up the SFB 49 Pulse block. A picture of the block is shown below. How do I set the block up to give a frequency between 0 and 2 000 Hz?
Address 300 (hex) means address 752 as set in HW Config.
I'm using a CPU313C.
