HART® devices from SW-Rev. 3.00
These devices can be reset to the factory setting, as well as to the setting according to the customer order.
With the menu item “Factory reset” in the service menu, the factory settings are reset to the factory settings according to the
following table (corresponds to standard configuration BS).
The menu item “Reset to Order” in the service menu is used to reset to the configuration ordered by the customer (default
configuration BS, customer-specific configuration without special user characteristic BF or customer-specific configuration with
special user characteristic BG).
The currently set HART protocol remains unchanged during a factory reset and a reset to order.
Devices with PROFIBUS PA®, FOUNDATION Fieldbus® and HART® (all SW revisions)
