PWM S7-1500.

Hello Everyone, I need some help.

I am trying to control the position of four RC servos - MG995, using a PLC S7-1500 CPU 1512C-1 PN, but I can’t find a way to do it. I’ve looked several times at the Siemens manual where it talks about PWM, and it says:

"Select analog drive connection
For the selection of the analog output, create a PLC tag of
the "Int" type with the corresponding address. The offset for the
PLC tag to the start address is 2.
To activate the output of the PWM signal, set the following
two bits of the control interface of the PWM channel in the
user program:
• SW_ENABLE (= Bit 0 in Byte 9)
• TM_CTRL_DQ (= Bit 1 in Byte 9)
The offset for byte 9 to the start address of the PWM
channel is 9."

But I don’t understand how to do this, or where to find these bits in TIA Portal. What are the steps I need to follow?. Any ideas?

¡Thanks!
