(3)
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 Pre-
reset Delay (1). Otherwise, set the next
stage to Idle (since the chromatograph is
now out-of-step with the S600+).
Delay, then set the flag for the Modbus
master process to reset the new data
flag at data address 3058. Set the next
stage to Wait for Reset Reponse.
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, then set the
next stage to Idle. This is the last stage
of the normal data acquisition cycle.

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 does not match the
S600+ cycle stream, then set the stage
to Pre-reset Delay (2). Otherwise, set
the next stage to Idle (since the
chromatograph is now out-of-step with
the S600+, most probably because
another S600+ has reset the new data
flag).
Delay, then set the flag for the Modbus
master process to reset the new data
flag at data address 3058. Set the next
stage to Wait for Reset Response (2).
