Hello everyone,
I inherited programming Horner PLC's after a month of training from the previous guy at my work. I have mostly taught myself and have run into a problem I can't seem to figure out how to code.
Basically I have a wind head that measures wind speed. I have 3 stages set. At stage 1 wind(5-9 mph) I want a drive I am controlling to not be able to go to it's max (4th preset) output. At stage 2 wind speed(10-14 mph) I don't want the drive to be able to output it's max or upper medium (4th and 3rd) preset. And at stage 3 wind (15mph and higher) I want the drive to not be able to output anything but the lowest setting.
The thing that stumps me is, I am selecting the drive output (1,2,3, or 4) with a sequencer in the program, if the wind speed will not allow the 4th preset to run, I want to go to the 3rd preset without the drive staying off for the duration of the 4th speed being selected in the sequencer and so on with each change in wind speed.
Can anyone understand what I just typed and my question? Or do I need to try and explain it any better?
Thanks for any help yall can give.
