Details
This trigger model template allows you to grade components and place them into up to four bins,
based on the comparison to limits.
To set a limit as unused, set the high value for the limit to be less than the low limit.
All limit patterns and the pass pattern are sent on digital I/O lines 1 to 4, where 1 is the least
significant bit.
After selecting a trigger model template, you can view the trigger model blocks in a graphical format
by pressing the front-panel MENU key and under Trigger, selecting Configure. You can also add or
delete blocks and change trigger model settings from this screen. You can use the
trigger.model.getblocklist() command to view the trigger model blocks in a list format.
