F-6 Appendix F - Variables Grouped by Fluidmove Activity
F.4 Carrier Level Variables and Equipment Constants
All variables in this table are defined as “Data Variables”. There is some redundancy here to allow the SECS/GEM host to collect the data real time as the
fiducials are found or by waiting until the board has been processed and collecting all of the data at once at the end of the program.
These variables will be overwritten each time a new board (carrier) is processed. The SECS/GEM host must collect the data immediately as each
corresponding collection event occurs or create a report containing the desired variables and attach the report to a collection event signaling processing of
the board is complete (such as “DispensingDone1” collection event 2002 ).

Description
BoardSequenceNumber 7800 U4 8800
Carrier Sequence # (sequential)
This number is reset each time “GO” is pressed. For a running board
count processed since powerup, see existing SV 106 (BoardCount).
WPFidFoundXY_1 7801 A[40] 8801 Workpiece Fiducial #1 XY in machine units (actual found)
WPFidFoundXY_2 7802 A[40] 8802 Workpiece Fiducial #2 XY in machine units (actual found)
CurrentFidFoundXY 7000 A[40]
8000
8801
8802
XY location of currently found fiducial in machine units. As fiducials
are found, this variable will be updated and either collection event
8000 (for pattern fiducials), 8001 (for workpiece 1 fiducial) or 8002 (for
workpiece fiducial 2) will be triggered.
By using this variable, fiducials can be collected at the moment they
are found. The XY locations will also be stored in variables 7801 (for
workpiece 1) or 7802 (for workpiece 2) or sequentially to variables
7001 to 7300 (for pattern fiducials) if it is more efficient to upload all
fiducial locations at once at the end of the program.
PATTFidFoundXY_1 –
PATTFidFoundXY_300
7001 – 7300 A[40] 2002
Sequential XY location (machine units) of found pattern fiducials in
order dictated by program
(300 max)
Collection event 2002 is an existing event that is triggered when
dispensing is done. A report can be created containing all or some of
the fiducial locations and then tied to CE 2002.
