• When the instrument completes the protocol or is stopped for any other reason, the instrument
state will be reported as
InstrumentReady
. This provides the option for the protocol to be re-
started using
StartatStep
or other administrator actions from the
InstrumentReady
state.
• When a user with administrator authority is logged in via the MES or without MES supervision, the
Pause
and
Advance
instrument buttons become active independent of protocol settings.
Instrument run status
The instrument status can be monitored on the Rotea
™
GUIor via the exposed OPC-UA variables.
• The
ProtocolState
will report
ProtocolRunning
or
ProtocolPaused
.
• The
ProtocolStepNumber
reports the current step.
•
WaitingUserAck
reports if the instrument is waiting for verification to proceed to the next step or
repeat the current step. The MES uses
SetProtocolState
to
RunProtocol
to repeat the same step,
or
SkipToNextStep
in response to this state.
MES batch history data
• The Rotea
™
Run Manager captures the run history data into a unique file each time the protocol is
run.
• Run history contains details of the process conditions throughout the run.
