Hello. Well, I need to use these instrucctions: PTO and PWM. I read the manual and I understood, I think so, but I have some doubts. I was reading about the bit enable status and said this:
The PTO EN (Enable Status) is controlled by the PTO sub-system. When
the rung preceding the PTO instruction is solved true, the PTO instruction
is enabled and the enable status bit is set. If the rung preceding the PTO
instruction transitions to a false state before the pulse sequence completes
its operation, the enable status bit resets (0). The EN bit operates as
follows:
• Set (1) - PTO is enabled
• Cleared (0) - PTO has completed, or the rung preceding the PTO is
false
So, the PWM is activated by the rung preceding, or by the rung where the pwm is?
