wbv8090 Posted November 24, 2010 Report Share Posted November 24, 2010 Hello, I have a problem I canâ€™t figure out with Visilogic. I am trying to create a program in which will be used to control a hydraulic press for a plastics factory. This requires â€œrecipesâ€ that have different times and pressures. I think I have figured out how to enter the recipes but the part I am stuck on is the analog output. I am using an analog signal from a pressure transducer and outputting analog signal to a +/-10V pump control (PSI) (using an IO-AI4-AO2) I canâ€™t figure out how to make the program reference the current system pressure then compare that to the users desired â€œtargetâ€ pressure then send the needed output to the +/-10v control. EX: The user requires a pressure of 600PSI and the transducer is reading 50PSI---- The program compares the difference then between desired pressure and actual pressure and analog outputs to the +/-10V pump control. THANKS!! Quote Link to comment Share on other sites More sharing options...
