How to Write PWM Programs for Siemens 200SMART PLC
When the PLC output type is transistor type, it has a high-speed pulse output function. There are two forms of high-speed pulse output: one is Pulse Width Modulation, abbreviated as PWM; the other is Motion Control Output, abbreviated as PTO. This article introduces how to write PWM programs for the Siemens 200SMART ST30 PLC. PWM … Read more
