    What is the difference between 1756 EN2TR and 1756-EN3TR?
    Answer. New series of 1756-EN2TR and 1756-EN3TR modules are physically different and use dedicated firmware. It is not possible to flash older module with the new firmware written for new series of the module. This change is due to component obsolescence.Feb 11, 2020
