Badger Meter M-Series M2000 - Manual (Page 11)

Universal Command #48 – Read Additional Device Status
Command #48 returns 8 bytes of data that is specific to the M2000 HART daughterboard The following table defines the
status information for the reply to this command Unused bits are not listed in the table and are always set to 0 Some of these
bits influence the device status bits shown in the Device Status Bits Set column:
Byte Bit Description Class Device Status Bits Set
0
0 Detector Error Error 4, 7
1 Empty Pipe Error Error 4, 7
2 Full Scale Flow Error Warning 0, 4
3 Totalizer Rollover Error Error 4, 7
4 Totalizer Rollover Status Warning 4
5 Flow Simulation Status Warning 4
6
Pulse Synchronization
Warning
Warning 4
7 ADC Interrupt Error Error 4, 7
1 0 ADC Range Error Error 4, 7
4
0
Internal Communication
Failure
Error 4, 7
1 Configuration Error Warning 4
The “internal communication failure” status bit, byte 4 bit 0, is set when MODBUS communication between the meter and the
daughterboard have failed Verify that the diagnostic, bi-color LED on the daughterboard is blinking both status indicators
(red and green) If both colors are not observed, then power cycle the meter
The “Configuration Error” status bit, byte 4 bit 1, is set when a mismatch between the meter’s configuration and that reported
over the HART protocol Generally, this implies the intended value for the parameter was invalid Below are some examples for
how this bit could be set
Example #1: Intended value is invalid
If the configured function for output #1 is set to 24V DC supply, the output type has to be normally open If the intended
value for the output type is normally closed, the configuration error flag will be set indicating the intended value was invalid
due to its dependency on the function of the output
Example #2: Writing to a secured meter
If connected to a secured meter, and you try to change a parameter after the login timer has expired, the “Configuration Error”
indicates that the parameter image between HART and the M2000 is not equal
