1.9 Health Check
The M6xx meters have several self-tests built in to ensure that the instrument is performing accurately.
The results of these self-tests are available in the Health Check register (AO:00), which is a simple 16-bit
binary value. Each bit represents the results of a particular self-test, with "0" indicating the test was
passed, and "1" indicating the test was failed. If Health status failures occur, the meter may have
experienced an operational failure. The table below provides a reference of error codes. Contact the
factory for further instructions.
A logical OR of the individual health check bits is available as a Binary input, with “0” indicating that all
tests have passed, and “1” indicating that at least one test failed.
Health Check Error Codes
Bit Description
0 Checksum error on analogue output (either 0-1mA or 4-20mA) calibration constants
2 Checksum error on gain calibration of inputs
4 Checksum error on phase calibration of inputs
12 Indicates firmware download in progress and measurements are offline
15 Protocol configuration error
1.10 Heartbeat State Counter
M6xx meters provide a Heartbeat State Counter Register that allows the user to determine the time
between successive polls. This counter will increment by the number of milliseconds that have elapsed
since the last time the data was updated. Another use of this register is as a visual indicator that the data
is changing; it allows users of certain MMIs to identify disruption in the polling of the instrument. The
Heartbeat State Counter is a full 32-bit counter that rolls over at 4,294,967,295 (4,294,967 seconds). The
counter starts at zero on power-up, and is NOT stored in non-volatile memory.
1.11 Meter ID Register
M6xx meters provide a "Meter Type ID" register for model identification purposes (AI:55) which returns a
value of 600 (BiLF12 Modbus, BiLF DNP), 601 (BiLF16 Modbus), or 602 (TUC DNP/Modbus).
1.12 Custom Points Lists
A custom points list can be defined for each DNP session. Select the session from the Session dropdown
box and click the “Edit Points List” button to begin editing the selected session’s points list.
