Bit Parameter Description
0x01 (LSB**) Cache validity Set to "1" when the HART Command 3
cache of the device is "empty".
0x02 (LSB**) Identification
ongoing Set to "1" when the Gateway is performing
a device identification procedure.
** LSB = least significant bit
Bit Parameter Description
0x80 Device malfunction The device detected a serious error or
failure that compromises device operation.
0x40 Configuration
changed An operation was performed that changed
the device's configuration.
