  1. When attempting to delete an unused IO Module I get "This module cannot be removed, because it is being used in the project. Please remove etc etc...." 

    I have deleted all IO associated with the unit and when use the "Find Tag" the only reference shown is HID Device Identifier. 

    How can I go about removing this module?

    • Alarms - Small Icon: Allow programmers to adjust position rather than being fixed at the top or bottom left.
      • Display the icon on the HMI programming pages
    • Web Server: Allow multiple instances of web server(connecting to on different ports) so programmers can set various page widths to suit the connecting devices, ie; mobile phone, tablet or PC.

  2. Is there anywhere in the ladder to show which 'Current Screen' is loaded? (I cant seem to find anything).

    I'm trying to run a function that returns to a 'Home' page after no users touch the screen for 15mins (which I have done), but I only want the 15min timer to run from screens which have adjustable settings and not the read only screens. From the 'Home' screen I've set up UAC that will require a login to get back into the screens with adjustable settings but can freely navigate to the read only screens.. 

    TIA

    Just another question.

    Is the communication problem a problem with the Modem, or with the PLC?

    If you say that you have communication problems after few weeks / months and the problem is in the PLC, then maybe this issue can be sorted if we find out why it happens.

    What do you suggest I do to see 'why' this happens?

  4. Hi all, 

    I realise that I can reboot from UniApps but is it possible to do a reboot from Ladder/HMI.

    Reason being, my Modbus IP comms (over 3G) seems to get 'bogged down' after a few weeks/months and stops communicating. My golf course customer then angrily complains when his lake overfills because the fill pumps haven't stopped as comms is lost, I then log on and reset it manually from UniApps and away it goes again until next time. 

    Id like to routinely reboot the PLC to prevent this scenario and also have a button on the HMI for the end user to press if needed rather than calling me. 

  5. Hello,
    I have a rain bucket to monitor every 0.1mm of rainfall. I would like to display how much rain there has been within the last 24 hours, 7 days and month.

    I thought the best way might be to use a data table and 'insert row' which would push out old values, but to then acquire the sum of the data table is a convoluted process. 

    Any suggestions on how I could achieve my goal?
