fn_SP_RampDN

In scenarios where it is essential to implement a gradual reduction of the set point, the fn_SP_RampDN block serves a critical function. This specialized block is engineered to facilitate a controlled and systematic decrease of the set point, allowing for adjustments to occur over a specified timeframe tailored to our operational needs. By employing this block, we can proficiently oversee the transition, thereby mitigating the risk of sudden fluctuations that may compromise the stability of the system.
