Good afternoon guys.
Thanks to all for the really good info I have gotten on the site thus far. Could not believe how many ways there are to do a "flip flop" circuit using only one button.
I need some help on a HMI though.
I'm using a Delta DOP-B10E615 HMI in conjunction with a Delta SX2 PLC.
All I want to do is push a start button and then the pressure on a test unit will go up until the mechanical bypass kicks in and holds the pressure at a certain level.
I have a 4-20mA transducer hooked up to the PLC which records on the HMI via the historical trend graph, which I can export as a Excel file via USB.
Then when I push stop, pressure releases on the test unit via a second "release valve"
Question is. How do I get the PLC and HMI to only start recording or "monitoring" the historical trend graph when I push the start button, and end when I push the stop button?
I'm dumbstruck as to where to start.
I also later want to add functions such as error screen popping up when for instance the overload on the hydraulic motor trips etc.. Baby steps though
Hope you guys can help.
