Response of the HART configuration changed maintenance message
1
If the HART field device signals "parameter reassignment" (configuration changed) in the 2nd
status byte, the module generates the maintenance message "HART configuration changed".
If the field device withdraws the message in the 2nd status byte within a minute, the
maintenance message is also deleted again by the module. If the message in the 2nd status
byte is still set after a minute, the module then independently sends HART command 38 for
resetting the message in the field device.
