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.

Address space

Abbreviations
• "IB" stands for input byte, that is, the module start address in the input area
• "QB" stands for output byte, that is the module start address in the output area
• "AQ" stands for analog output
• "QAQn" stands for value status (QI) of the analog output n
• "QC"stands for Quality Code
Evaluate value status
There is one bit value status for each analog output in the input address space.
Irrespective of the diagnostics enables, each value status (each QI bit) provides information on
the validity of the corresponding process value.
• Value status = 1: Process value okay, "good"
• Value status = 0: Process value not okay, "bad"
Generally, the value status is set to "good" if the analog value can be output without errors. The
value status is set to "bad" in the following cases:
• The analog value cannot be output due to an error.
• The analog output is deactivated.
• The substitute value is output at the analog output.
