    Hi Mikhai,
    I have a problem with the scheme. Specifically, I want to setup so that the user can EDIT the text on the scheme. (The purpose of the edit is to set the maximum and minimum value alarms for the temperature).
    However, I don’t see any text components that allow the user to edit. Can you help me?

    Hi,

    You should create an output channel in the configuration database, and add a button on a scheme. When a user clicks the button, a popup displayed to enter a new value.

    In the formula of output channel, you can set a value of input channel:
    SetVal(101, Cmd)
    where 101 is the input channel number.

    Hi,

    You should choose:
    1. Send command to the OPC server.
    Disable the formula of the output channel.

    2. Write value directly to the input channel.
    Change input channel type to the Calculated real and set the Signal field to blank.

    The settings depends on the choice. If you work with OPC, probably the 2nd option is better.
