Fieldbus Diagnostics application
The measurements are labeled with a status of GOOD, BAD, or CHECK. You can configure
the measurement criteria and ranges for the GOOD and BAD status labels. The INACTIVE
status is displayed when there is no fieldbus signal, due to no device communication on
the fieldbus segment. Review the measurement criteria in Settings to ensure they are
appropriate for your installation.
