Hello, new here but i have experience programming unitronics PLCs. A year ago i program one Vision 700 PLC for an oven. The program manage the oven and record temperatures. When the process ends. PLC send an email with the recordings. After three months with daily use the PLC stop working correctly. The user cant change the variables throught HMI. When touch the Variable box in HMI to change it nothing happened. The touch screen worked fine and user can touch other HMI Buttons but not Variables. What i did was zero all the PLC operants to default. Then everything works fine.After some time of use the same problem happened. I am trying to find a solution. My thought is that this has to do with an SB or SI but not sure. The program seems ok with no compile errors. Waiting for help. -
Is there a way to use variables to define the tags used in objects (buttons, number boxes, etc.) on an HMI screen? Here is my situation... and I'm sure everyone else has run into this. I have four identical servos: SRV01, SRV02, SRV03, SRV04. I have one screen created for the inputs and one screen for the outputs for SRV01. I want identical screens for the other servos. I hate the monotonous task of changing all of the tags one by one. There has to be an easier and faster way. I would like to be able to change a variable (SRV0#) based on which screen I am currently on. This would be the easiest. I'd settle for a way to change the tags in a list versus having to click into each and every box and button. Buttons are the worst with the tags buried in the "collection" and having to change the set and reset. There has to be an easier way that I have not found.
