Regardless of whether you want to test a block created in STL, LAD, or
FBD, you can always:
S Define the trigger condition,
S Select the test environment and
S Define the settings for the test display.
We will explain the meanings of
these settings below!
When you set the trigger condition, you set the call environment for the
block to be tested. The test function is only executed if the trigger condition
set is also fulfilled. You can choose between three different settings, as
shown in Figure 7-2:

Figure 7-2 Defining the Trigger Condition
For the sample program, the default setting ‘No Condition’ applies since the
call environment of the block to be tested is not important.
