Event Table

The Event Table enables to trigger action with specified Output based on events from selected Input. Event Table tab is common to all devices on the same Clarity Instrument.

Inputs:

  • Acquisition and Idle events - Time, signal level, digital input state
  • Events from Control module - Auxiliary signal level
  • System events - Begin and end of sequence, acquisition etc.

Outputs:

  • Digital Output control - DataApex A/D Converters, selected Control modules (for more details see also chapter Events used in Active Sequence).
  • Acquisition and Sequence control commands (Stop, Abort, Skip Vial, etc.).
  • Run program - Launching an external program, with/without start parameters. Basic set of external tools is supplied with Clarity.
  • None - Nothing will happen, suitable for development and testing of the method.

Each row in the table represents an independent event. When several events controlling the same output collide, the subsequent event masks the preceding one. When two events occur simultaneously, the event listed as last in the Event Table prevails.

Some events occurs in Running or Idle state only, these are coined with Run or Idle words in the event name.

Method Setup - Event table

Individual lines or the entire table of events may be erased by right clicking the mouse on the available context menu above the table and using Delete Row or Delete All Rows commands. When a line becomes invalid, it will be highlighted with red background. Such row may be edited and must be repaired prior to saving the method. It is possible to select and copy the whole rows, paste them in the table and modify them. This is useful for creating sets of similar events.

Name

Arbitrary name to describe the event.

Input

The set of columns describing the Input that will trigger the action specified in Output columns.

Type

Sets the type of the input. Available options are shown in the Tab "List of events available in the Event Table":

List of events available in the Event Table

Name of the event Condition on when the event is triggered
Run Time > Duration of acquisition (Instrument in Running state) exceeds adjusted value (reset by every start of acquisition).
Input Run > Measured quantity (e.g. input voltage or AU) exceeds adjusted value (works in Running state only).
Input Run < Measured quantity (e.g. input voltage or AU) drop below adjusted value (works in Running state only).
InpRel Run > Measured quantity (e.g. input voltage or AU) exceeds adjusted value+offset (works in Running state only, offset is locked in the moment of acquisition start).
InpRel Run < Measured quantity (e.g. input voltage or AU) drop below adjusted value+offset (works in Running state only, offset is locked in the moment of acquisition start).
Time Idle > Duration of idle time (Instrument in Waiting or Ready state) exceeds adjusted value (reset by every sending of method and by the end of the acquisition).
Input Idle > Measured quantity (e.g. input voltage or AU) exceeds adjusted value (works except Running state only).
Input Idle < Measured quantity (e.g. input voltage or AU) drop below adjusted value (works except Running state only).
InpRel Idle > Measured quantity (e.g. input voltage or AU) exceeds adjusted value+offset (works except Running state only, offset is locked in the moment of method sending).
InpRel Idle < Measured quantity (e.g. input voltage or AU) drop below adjusted value+offset (works except Running state only, offset is locked in the moment of method sending).
Dig. Input Run Digital input changes its state (works in Running state only).
Dig. Input Idle Digital input changes its state (works except Running state only).
Aux Run> Auxiliary input level exceeds adjusted value (works in Running state only)
Aux Run< Auxiliary input level drop below adjusted value (works in Running state only)
Aux Idle> Auxiliary input level exceeds adjusted value (works except Running state only)
Aux Idle< Auxiliary input level drop below adjusted value (works except Running state only)
Ready All connected hardware becomes ready.
Run Begin Run has begun, i.e. start of acquisition, start of the sequence row (before injection and after injection), but not the restart.
Injection Start of the sequence row, Instrument is waiting for carrying out the injection.
Bypass Injection Start of the bypassed sequence row (row withSample Type = Bypass value set).
Acq Begin Acquisition has begun, i.e. start of acquisition, start of the sequence row (after injection or bypass), but not the restart.
Restart Acq Restart of acquisition (by wire or manually by button).
Acq End Correct completion of acquisition (Autostop or Stop button).
Run End Completion of acquisition (Autostop, Stop button, Abort button).
Control Elapsed Completion of acquisition and all programs on controlled devices (e.g. gradient program on pump or temperature program on column oven).
HW Error Hardware error occurred (e.g. error on communication, device firmware error or physical failure).
User Abort Abortion of acquisition by Abort button.
User Shut Down System was shut down by user (using button on Device Monitor, command is available with controlled device connected only).
Close Instrument Instrument was closed.
SST OK On the end of acquisition, when SST resulted with OK.
SST Unknown On the end of acquisition, when SST resulted with Unknown.
SST Failure On the end of acquisition, when SST resulted with Failed.

Notes:

Waiting for injection state is considered as Idle from event table's point of view, so for correct launching of e.g. Stop Seq command on any circumstances is necessary to create two events with the same command, one for Run and one for Idle state.

Notes:

SST events occurs only when acquisition is finished.

Notes:

User Shut Down event is available with controlled device connected only and after removing corresponding device from configuration particular event table row must be removed too.

Notes:

In the event table, controlled devices are listed under names entered in their configuration dialogs, after change of name of the device, particular event table row must be corrected or removed.

Source

Sets the device which should be used as Input (e.g. detector, A/D converter, …).

Input

Applies only for Digital Inputs, where it sets the input number.

Value

Indicates the value that is to be compared during the acquisition with current values (time, voltage on detector, digital input state etc.).

Note:

When using Events evaluating Input values (Input Run, InpRel Run, Input Idle, InpRel Idle), please note that event will be triggered only when the change of input signal will be greater than EventThreshold value set in OTHERS.INI file.

Note:

When triggering Events based on Auxiliary Signals (Input Run, Input Idle, Aux Run, Aux Idle), please note that event will be triggered only when the change of input signal will be greater than specific EventThresholdAux value set in OTHERS.INI file.

Units

Units of the Value (if applicable). For detectors, these are the units set in the Device Setup dialog of the System Configuration dialog. This field is not editable.

Output

The set of columns describing Output triggered by the action specified in Input field.

Output Type

Selects from the available output options:

  • A/D converter (INT7, INT9, U-PAD, Net-PAD, etc.) - digital outputs
  • Controlled device (Agilent 6890, etc.) - digital outputs
  • Run Program - runs external program, command line parameters can be set.
  • None - Nothing will happen, suitable for development and testing of the method. (e.g. when it is needed to log event in the chromatogram)

Note:

There are two auxiliary software utilities in the \Bin\UTILS subdirectory. SENDCOM.EXE for sending simple commands over serial line and BEEP.EXE for acoustic signaling, check the text files in the \Bin\UTILS subdirectory for detailed description.

Output

Meaning of this field varies according to the Output Type used:

  • A/D converter - sets the number of the controlling output to be set to the value indicated in the Parameter field.
  • Controlled device - sets the name/number of the controlling output to be set to the value indicated in the Parameter field.
  • Run Program - sets the filename of the software to be run (including the full path).
  • Command - sets the command for internal controlling of the software run:

List of possible outputs for the Command output type

Name of the command Meaning of the command
Start Seq Start of the Sequence. Sequence file must be properly filled and saved in order to execute this command.
Start Acq Start of the acquisition. When launched in Running state, restarts the acquisition only with Start-Restart option checked (for more details see also chapter Measurement) .
Snapshot Creates a snapshot of currently running analysis. Snapshot processes and saves the data from currently measured sample without terminating the measurement.
Stop Acq Stop of the acquisition. In sequence run, current acquisition is halted, the Sequence continues on the next row.
Stop Seq Stop of the Sequence. Current acquisition will be finished, then the sequence will stop.
Repeat Injection Acquisition of current row in Sequence is halted immediately, the same sample is injected and analysed again.
Skip Vial Acquisition of current row in Sequence is halted immediately, the Sequence continues on the next row.
Abort Aborting of Single Analysis or the Sequence (chromatogram is always saved, regardless of setting in GLP options).
Shutdown Shutting down all the devices connected (command is available with controlled device connected only).
LC Hold/Resume Holds or Resumes the execution of the Gradient Table at the actual flow and mobile phase composition. Type of action depends on current state of the device.

  • A/D Converter: The level to be set on the corresponding output specified in the Output field:

High - High level (output voltage 3 to 5 V) - corresponds to an opened contact.

Low - Low level (output voltage 0 to 1 V) - corresponds to a closed contact.

Pulse - Inverts the current level of the output for a given time and then returns back. Implicit length of the pulse is 1 sec.

Note:

The duration of the pulse can be adjusted in the others.ini file (for more details see also chapter others.ini file).
