I am seeing the error code related to an analog output point on a profibus network. It is an ABB_TZID_x10_PA, if that helps. The description is "Maintenance required". We are not seeing any issues with the device in the field, and it seems to be working fine (a tech tred a few things including powering the device off/on - but the message is still there). Is this a concern? How do we clear the message (hitting the Clear latched unit status button doesn't do anything)?
