Alerts - OOC and OOS Conditions
SPC Express can generate a variety of Alerts whenever a process goes
Out-of-Control, a sample is Out-of-Spec, or a sample is Out-of-Range.
Here are your choices:
- Subgroup Out-Of-Control ( § ):
- Pop-up a User-Defined Text Message (up to 10 lines long).
Purpose: Alert the operator that a subgroup is out-of-control and show him/her a text
box containing additional information or instructions.
This can be defined either globally or on a characteristic basis.
If "Global", enter this into Extra Options (in File/Global Preferences): OOCMSG=filename.txt
The txt file must be in the "Start-in" folder.
If "by Characteristic", enter this into Special Instructions (Edit/Edit the Current Char/Optional Info Tab): *OOCMSG=filename.txt
The txt file must be in the Part File Folder.
Create the txt file using NotePad or other similar editor.
- Pop-up a Prompt to enter a Comment to be saved with the subgroup.
Purpose: Alert the operator that a subgroup is out-of-control and ask him/her to
enter a comment which will then be saved with that subgroup.
Global Preferences - Check the "OOC Log" box on the General Tab.
Enter this into Special Instructions (Edit/Edit the Current Char/Optional Info Tab): OOCNOTE=[Comments]
(or whatever traceability field is to be used)
A new option was added 05-04-2016 to allow you
to prompt for both "Assignable Cause" AND "Corrective Action".
Enter the option: OOCNOTE=[AC/CA].
In order for this to be used, you must have traceability fields with those two exact names.
You may also specify this globally (in the Extra Options field of Global Preferences),
but any local definition in the Characteristic's Special Instructions field can be used
to over-ride the Global setting.
Watch Out! If you specify this globally, the assumption is that ALL of your part files
will have a traceability field with whatever name that you specified.
You may also generate an alert when a new subgroup is not just out-of-control but in the "yellow zone".
Enable this feature by typing OOCALERT=YELLOW in the
Extra Options field in Global Preferences.
Note: Out-of-Control conditions will only be checked if you are using Extended Control Limits
or if you have specified OOC=DYNAMIC.
- Send an Email.
Purpose: Send an email to one or more people whenever a subgroup is out-of-control.
Fill in the email parameters in Global Preferences on the AutoScope & Email Tab.
By default, you will get an email for every SG that goes out-of-control. However, you may
set an option to only get an email every so often in the case of consecutive SG's being out-of-control.
Special Option (and Special Instruction) AlertLatchOOC=nn to specify how many SG's to
latch before sending another email alert.
For example, if you set the Latch to 5, we'll send an email on the first OOC SG,
but then not another alert until 5 more have occurred. Legal values are 0 to 500.
(this feature requires version 06-06-2016 or newer)
If Out-of-Control email messages are enabled globally, you can now turn them off selectively on a char-by-char basis.
(this feature requires version 09-07-2016 or newer)
( § )
Out-of-Control is defined as a subgroup which is beyond the Extended Control Limits.
If you need Trend, Shift, or Computer Calculated Limits checking,
please contact Major Micro Systems for additional instructions.
Note: Use Special Option "OOCALERT=YELLOW" to generate OOC Alerts (including email) if
a point is in the yellow zone in addition to the red zone.
Note: For Attribute data, Control Limits may be expressed in decimal, percent, or PPM
and the out-of-control check will assume a P-Chart. (requires version 03-27-2012 or newer)
- Sample Out-Of-Spec:
- Pop-up a User-Defined Text Message (up to 10 lines long).
Purpose: Alert the operator that a sample is out-of-spec and show him/her a text box containing
additional information or instructions.
This can be defined either globally or on a characteristic basis.
If "Global", enter this into Extra Options (in File/Global Preferences): OOSMSG=filename.txt
The txt file must be in the "Start-in" folder.
If "by Characteristic", enter this into Special Instructions (Edit/Edit the Current Char/Optional Info Tab): *OOSMSG=filename.txt
The txt file must be in the Part File Folder.
Create the txt file using NotePad or other similar editor.
- Send an Email.
Purpose: Send an email to one or more people whenever a sample value is out-of-spec.
To activate this feature, you MUST define an
Extra Option called OOSEMAIL=YES.
Fill in the email parameters in Global Preferences on the AutoScope & Email Tab.
Note: You can also send an email if any one attribute sample is out-of-spec on the
high side. To do this, define an
Extra Option called OOSATTREMAIL=YES.
- Pop-up a Prompt to enter a Comment to be saved with the subgroup.
Purpose: Alert the operator that a sample is out-of-spec and ask him/her to
enter a comment which will then be saved with that subgroup.
Enter this into Special Instructions (Edit/Edit the Current Char/Optional Info Tab): OOSNOTE=[Comments]
(or whatever traceability field is to be used)
You may also specify this globally (in the Extra Options field of Global Preferences),
but any local definition in the Characteristic's Special Instructions field can be used
to over-ride the Global setting.
Watch Out! If you specify this globally, the assumption is that ALL of your part files
will have a traceability field with whatever name that you specified.
Note: If more than one sample in a subgroup is out-of-spec, there is the danger
that the second comment entered will over-ride the first comment entered.
If this is a concern, enter the Special Option OOSNoteDefer.
This will defer the activation of the OOSNote prompt until all samples have been entered and the SG is full.
This solves the problem of two or more samples being out of spec and your second comment over-writes the first.
- Sample Out-Of-Range:
- Pop-up a Warning Message.
Purpose: Alert the operator that a sample is out-of-range and either deny the use of that
sample value or ask the operator if he/she wants to use it anyway.
If you want to alert the operator if a sample is outside a certain range,
in the Formula field of the Characteristic (Edit/Edit the Current Char/Input Options Tab) ...
a) Enter MIN=x.xxx, and/or
MAX=y.yyy, to define the Range Limits,
b) Enter Popup=Deny, to let the operator know
that the reading will be denied,
or
c) Enter Popup=Warn, if you want to alert the
operator but allow the operator the option to use the sample anyway.
