Hi,
I've been trying to implement a dynamic setpoint for a pid control, and my idea is to use the instruction Curve. Basically my goal is to use a timer from 0 to 100 seconds, and based on the timing value, calculate a setpoint using a table with different values.
maybe i am using the wrong instruction. long time ago, i used an instruction block on a rockwell plc to convert a non-linear instrument into a linear one. what i am trying to do now is the opposite.
at this point, im just testing the instruction by typing directly a value at the INPUT, and the OUTPUT is just a mirror of the input.
any help would be really appreciated.
