States
• These production
events are in Scorpion
called: “States”
• The States are created
and defined in the
“Settings” mode
SL-2005-022-a Introduction to Scorpion 4.0
June 12,2005 Page 21
Example of States
SL-2005-022-a Introduction to Scorpion 4.0
June 12,2005 Page 22
Communicating the results
• The name of the State
is displayed in the
Inspection Result
Panel
• Text and colour is user
defined
SL-2005-022-a Introduction to Scorpion 4.0
June 12,2005 Page 23
Defining the constrains
• One or more logical
conditions can be used
• A logical condition is
either true (value=1) or
false (value=0)
• The logical conditions are
set in the tool box based
on testing results from any
vision tool against user
defined conditions
(distance, area, radius)
SL-2005-022-a Introduction to Scorpion 4.0
June 12,2005 Page 24
Define related commands
• Depending on
inspection result
(States), one or more
commands can be
executed:
– Sending status info to
PLC or Robot
– Sending data to PLC or
Robot or a database
– Save images

Inspection criteria
• A logical test of one or more measured
parameters generated by the vision system
• Used to define the Logical States equivalent
to the events that may occur in the
production line
SL-2005-022-a Introduction to Scorpion 4.0
June 12,2005 Page 27
Defining Inspection criteria
• Select inspection parameters:
– Measurements of area, dimensions (line, distance,
radius)
– Read or verify text or code
– Verify a colour or greyscale surface
– Find or verify position and rotation
– Counting number of areas, lines, circles
• Set inspection tolerances:
– Acceptable +/- values for each inspection parameter
SL-2005-022-a Introduction to Scorpion 4.0

Example of inspection criteria
• Logical States
– Object Present
– Type of object
– Inspection Passed
– Cannot measure

• Parameters
– Area of object within
certain limits

Sending Status data to a PLS
• We want to send status
data (object present or
absent) using the RS232
interface
• We will link the timing of
sending the data to the
event ”Inspection”
• Initially the event
inspection activate the
command ”Inspect”.
• After that we want the
system to send status data
SL-2005-022-a Introduction to Scorpion 4.0

Testing the communication
• Add a new RS 232
command
• Select the parameters to be
sent (All parameters from
all tools are available)
• In ”Communication” tab
you can monitor both
outbound and inbound
messages
