3.5.1.1 Command 48 Data
The “More Status Available” bit in Device Status will be set if any bit in the following command 48 data is set, which
previously was not set:
• DeviceSpecificStatus_0 (bytes 0-3 only – hardware faults)
• ExtendedDeviceStatus
• StandardizedStatus
• AnalogChannelSaturated
• AnalogChannelFixed
• DeviceSpecificStatus_1 (bytes 14-17 – hardware warnings)
NOTE: DeviceSpecificStatus_0, bytes 4-5 (main board status information) is provided only for additional
information but these bits will not trigger More Status Available, as these are not considered faults or warnings.
DeviceSpecificStatus_1, bytes 18-21 (device status information) is provided only for additional information but these
bits will not trigger More Status Available, as these are not considered faults or warnings.
3. Upon receiving this command the device shall compare the counter value received in this command with the device’s current value. If they do not match then the device
will return Response Code 9 “configuration change counter mismatch” and not reset the configuration change counter.
4. HART specification allows up to 25 bytes for this command. However, it also states that “the response data bytes returned are truncated after the last status byte
supported by the Field Device”. Therefore we only return 22 bytes of data in our response. If the master sends a request with more than 22 bytes of data, our device will
still respond, but the extra bytes beyond those supported will be ignored
