brew OFFLINE Expert Boarder Posts: 108 Karma: 0	marc, do you mean that a subroutine in the PLC will output a signal that is a sine wave? like the X is the amplitude and the Y is the HZ? and you can adjust the X and Y numbers? bill

Hi Bill,

To be honest, yes...
I have tried the XYCurve and completely forgot I even created a video many moons ago about application programming but I can't reproduce it.
It's a shame there is no small signal generator implemented in proview.
I need the continuous adjustable sine as an input in a (PID) controller for (educational) testing purpose.
The step and ramp is not a problem.

An ideas? I think I have a black spot in my memory again.

Great to hear from you again.
How are you and the brewery/beer business?

claes OFFLINE Platinum Boarder Posts: 3177 Thank you received: 502 Karma: 133	Hi Marc, You can use a Timint connected to a Sin. The input of the Timint will influence the frequency. For the amplitude you can set FactorVal in the Sin object with a StoAp. You might have to reset the timint now and then to avoid loss of significance after long times. /Claes

brew OFFLINE Expert Boarder Posts: 108 Karma: 0	Hi Marc, Claes beat me to it! The brewery is done. Just some upgrades every once an a while. Proview never crashes on me... works for weeks and weeks... I will post the complete program soon, so people can play with it. Come on by and drink some beer -- made by Proview! bill
