Status code der AGA-10 calculation
Coordinate AW-01 gives the status code of the AGA-10 calculation. This is a bit-
coded value represented as a hexadecimal code. A value of "0000h" indicates a
AGA-10 calculation with errors. The meaning of the individual bits are:
Bit
Meaning
0
Components invalid
Sum of the un-normalized gas components
is <= 0 or > 110 mol-%
1
Timeout of new gas data exceeded
Within the defined time period in AX-07, no new data arrived. Possible
reason:
• Time too short
• Communication interrupted
• transfer register has not been filled (for Modbus slave)
• Wrong RMGBus telegram or wrong stream selection
If there are new gas components latest within three times of the given
timeout time, the error status will be reset.
2
Temperature Error
The temperature measurement is disturbed. Calculation will be done
with the default value.
3
Pressure errors
The pressure measurement is disturbed. Calculation will
be done with the default value.
4
Simulation active
Parameter E-01 „USE09 mode" is set to simulation no data (results) of
the DSP will be accepted
5
no value
6

Error AGA-10 calculation
There is an error within the AGA-10 calculation. The calculation is on
hold. Reason may be wrong pressure or temperature values, ...
9-15
no value
The message "188: AGA-10" appears, if the status code is not 0. The Modbus
master function is flexible in order to support PGC's other manufacturers, too; for
example a Siemens PGC. Activating the RS 485 interface as Modbus master is
described in chapter 10.3.3, "Interface 2" on page 150.
