5.3.4.5.3 AnalyserChannel_ OperatingModeExecuteSub StateMachineType States

Table 78 specifies the AnalyserChannel_OperatingModeExecuteSubStateMachine’s State Objects. These State Objects are instances of the StateType defined in [OPC 10000-5]. Each State is assigned a unique StateNumber value. Subtypes of the AnalyserChannel_OperatingModeExecuteSubStateMachineType can add References from any state to a subordinate or nested StateMachine Object to extend the FiniteStateMachine.

A standard set of sub-states are defined for AnalyseChannel_OperatingModeExecuteSubStateMachineType. These sub-states represent the operational condition of the AnalyseChannel_OperatingModeSubStateMachine Execute state. All the sub-states must be supported, though they can be transient states.

Table 77 – AnalyserChannel_OperatingModeExecuteSub StateMachineType State Descriptions

StateName	Description
SelectExecutionCycle	This pseudo-state is used to decide which acquisition path shall be taken. This decision is made using a Parameter ExecutionCycle that can be: Provided as a Parameter of the StartSingleAcquisitiont Method Update by the vendor specific software and exposed in the AnalyserChannel.AcquisitionStatus FunctionalGroup The state machine waits at this state until the underlying system is ready to take a given acquisition path.
WaitForCalibrationTrigger	Wait until the analyser channel is ready to perform the Calibration acquisition cycle, for example: The external trigger is received from another system A vendor specific Parameter in the AcquisitionSettings has been updated For analysers that do not need the step, the state is transient.
ExtractCalibrationSample	Collect / setup the sampling system to perform the acquisition cycle of a Calibration cycle, for example: Empty and dry the sample liquid cell. Place a calibrated sample in the acquisition path. For analysers that do not need the step, the state is transient.
PrepareCalibrationSample	Prepare the Calibration sample for the AnalyseCalibrationSample state ,for example: Heating the Calibration sample Homogenizing the Calibration sample For analysers that do not need the step, the state is transient.
AnalyseCalibrationSample	Perform the analysis of the Calibration Sample, for example: Collect the reference spectrum Collect the particle size histogram
WaitForValidationTrigger	Wait until the analyser channel is ready to perform the Validation acquisition cycle, for example: The external trigger is received from another system A vendor specific Parameter in the AcquisitionSettings has been updated For analysers that do not need the step, the state is transient.
ExtractValidationSample	Collect / setup the sampling system to perform the acquisition cycle of a Validation cycle, for example: Empty and dry the sample liquid cell. Place a calibrated sample in the acquisition path. For analysers that do not need the step, the state is transient.
PrepareValidationSample	Prepare the Validation sample for the AnalyseValidationSample state ,for example: Heating the Validation sample Homogenizing the Validation sample For analysers that do not need the step, the state is transient.
AnalyseValidationSample	Perform the analysis of the Validation Sample, for example: Collect the Validation spectrum and compare it with the expected values
WaitForSampleTrigger	Wait until the analyser channel is ready to perform the Sample acquisition cycle, for example: The external trigger is received from another system, like an external sampling system A vendor specific Parameter in the AcquisitionSettings has been updated For analysers that do not need the step, the state is transient.
ExtractSample	Collect the Sample from the process, for example: Physically extract a Sample from the process to fill a liquid cell Extract powder from the blender Some analyser probes do not need to extract the Sample from the process, for example a NIR reflectance probe. In this case, this state is a pass-through.
PrepareSample	Prepare the Sample for the AnalyseSample state, for example: Heating the Sample Homogenizing the Sample For analysers that do not need the step, the state is transient.
AnalyseSample	Perform the analysis of the Sample, for example: Collect the Sample spectrum Collect the Sample particle size histogram Collect the Sample chromatogram
WaitForDiagnosticTrigger	Wait until the analyser channel is ready to perform the Diagnostic cycle, for example: The external trigger is received from another system A vendor specific Parameter in the AcquisitionSettings has been updated For analysers that do not need the step, the state is transient.
Diagnostic	Perform the Diagnostic cycle. This cycle is a placeholder allowing the analyser vendor to extend this state to represent vendor specific analyser diagnostic cycles.
WaitForCleaningTrigger	Wait until the analyser channel is ready to perform the cleaning acquisition cycle, for example: The external trigger is received from another system A vendor specific Parameter in the AcquisitionSettings has been updated For analysers that do not need the step, the state is transient.
Cleaning	Perform the cleaning cycle.
PublishResults	Publish the results of the previous acquisition cycle. When the transition from PublishResults to CleanupSamplingSystem occurs, all results must be available.
EjectGrabSample	The Sample that was just analysed is ejected from the system to allow the operator or another system to grab it and send it to a control lab for example.
CleanupSamplingSystem	Cleanup the sampling sub-system to be ready for the next acquisition, for example: Flush the liquid cell with a solvent For in-process probes, this state is transient.

The set of states defined to describe an AnalyserChannel_OperatingModeExecuteSubStateMachine can be expanded. Sub-states can be defined for the base states to provide more resolution to the process and to describe the cause and effects of additional stimuli and transitions. See Table 77 for a description of the states.

ExecutionCycle, ExecutionCycleSubcode and ActiveStream Parameters are set during the SelectExecutionCycle state. From the end of SelectExecutionCycle to the end of CleanupSamplingSystem, these two Parameters shall not change.

ExecutionCycle, ExecutionCycleSubcode, ActiveStream and IsActive Parameters are set during the SelectExecutionCycle state. From the end of SelectExecutionCycle to the end of CleanupSamplingSystem, these two Parameters shall not change.

WaitForxxxTrigger states represent waiting for situation like:

•External input i/o visible or not in the address space

•Internal timer (visible or not in the address space)
