There’s something wrong with the application or the operating system. There is zero service information available for the 475. Only the Emerson factory can fix it.
The 475 was made obsolete some time this past year. The Emerson 475 web page says support is only offered through October 2020. https://www.emerson.com/en-us/catalog/ams-475-field-communicator
Anecdotal information on repairs of 475’s was that it was a very expensive exercise. Given the fact that it’s a boat anchor in 22 months, do you want to throw good money after bad?
Can you use a Meriam handheld or Pactware software with a HART modem instead of a 475?
