Wait up to the time-out period for the
2551 to respond. If no reply has been
received, then set the telemetry fail
alarm and set the stage to
Idle
.
If a reply
has
been received
and
the new
report available flag is still set
and
the
report stream still matches the S600+
cycle stream, then set the stage to
Process the Analysis Report. Otherwise,
set the next stage to Idle (since the
chromatograph is now out-of-step with
the S600+).

Process the Analysis
Report
1. Reorder the raw telemetered mole
percentage into S600+ internal order
(as directed by the received
component codes, which run in
ascending values from 100).
2. If configured to do so, check low/high
and deduction limits
3. Normalise the reordered mole
percentage set.
4. If enabled (that is, non-zero values
entered), apply the additionals.
5. If enabled, apply the C6+ or C7+
splits.
6. Copy the processed mole
percentage set into the latest
processed set.
7. If enabled, perform critical alarm
checks on peak overflow, etc.
8. If enabled, perform non-critical alarm
check on ADC fails, etc.
9. If there are no limit, critical, or
deviation alarms, then mark the
analysis as good, copy the
processed mole percentage set into
the last good set, update the RD and
CV, and record the time.

Delay after Report
Wait up to the specified time, then set
the flag for the Modbus master to poll for
