[?]: Auto Tuning of fb58 using pulse output

[reymond_craig]

Good evening,
I just want to ask if someone already try doing auto tuning of temperature controller fb58 using pulse output only.
Most documentation from siemens describes auto tuning using the analog output.
I hope someone already succeed on doing auto tune by using only pulse output.
Thank you very much in advance

I dont see very big difference between analog output and PWM output. Lag time of a process is usually much bigger than PWM period, so it doesn't affect the result-> it is almost equal to have a proprtional actuator.
