    Hello.

    I would like to implement a data history in the following way.

    When a bit of a specific address mw90.0 is activated. Read a specific byte (mw100).
    And store that value in a data record.

    The idea is to have a record of the number of refueling and the kg of a dispenser.

    any suggestion.

    Thanks in advance.

    Hello,

    Try the following approach:
    1. Use Automatic Control Module to send a device poll command when the 1st input channel > 0.
    2. After reading the new value will be put into the 2nd input channel. This input channel should have event flags to write events on change.
