I have a hydralic cylinder that is controlled by 0 to 24V i want to automate it by using this ramp up and ramp down function. Thank you Mudasar

The prograam is not perfect. If you chanche from up to down (or from down to up) and the ramp of up is not yet reached the end the output jumps. If its a problem, you can ask me for a better programm, i think of it..... You must also use a signalconverter 0-10V convert to 0-24VDC Attachment 2xRamp.zip (489 Downloads)
