Hamilton Sundstrand Company Fuel Metering Valves XVG - Manual (Page 33)

All XVG/eXVG parameters can be uploaded using Modbus Read Registers
function then convert the results into appropriate number representation for display
and monitoring. Model number and part number need to be converted into ASCII
character string. All registers are readable, choose whichever parameters are of
interest and read them.
10.2 Accessing Fault Records Procedure
The following parameters will be used to retrieve the XVG/eXVG fault records.
There are a maximum of 16 records available in the valve. The first eight are
permanent records, the other records are updated on a first-in first-out basis. When
there were 16 fault records in the valve, the oldest non-permanent record will be
deleted when a new fault record is created.
