Description

 

 
 

 

Default  

Runs the selected subset of tests (1-9). 

 
 

 

Stepping Steps 

Runs the selected subset of steps (1-126). 

 
 

 

Looping Tests 

Runs the selected subset of tests (1-9) repeatedly. 

 
 

 

Looping Steps 

Runs the selected subset of steps (1-126) repeatedly. 

 
 

 

Slow Tests 

Runs the selected subset of tests (1-9) with a pause 

 

 

between the execution of each test. 

 
 

 

Slow Steps 

Runs the selected subset of steps (1-126) with a pause 

 

 

between the execution of each step. 

 
 

 

Slow Looping Tests 

Runs the selected subset of tests (1-9) repeatedly with a 

 

 

pause between the execution of each test. 

 
 

 

Slow Looping Steps 

Runs the selected subset of steps (1-9) repeatedly with a 

 

 

pause between the execution of each step. 

 
 

 

Display Step Line 

Runs the selected subset of steps (1-126) and displays the 

 

 

subroutine commands executed for each step. 

 
 

 

Display/Hold Lines 

Runs the selected subset of steps (1-126) and displays the 

 

 

subroutine commands executed for each step.  With this 

 

 

mode you must input a keystroke to continue after each 

 

 

command is executed. 

 
 

 

Over Night Loop 

Runs the selected subset of steps (1-126) repeatedly until  

 

 

an error is encountered or the module is reset.  If you select  

  

the 

All

 option from the second-level menu, all steps but  

 

 

the DIP switch and trigger steps are executed.  Since the  

 

 

DIP switch and trigger steps are interactive, they are not  

 

 

included in the Over Night Loop tests. 

 

 
 
By default, test result messages are printed to the serial port as each test is executed, and 
diagnostics execution terminates if an error occurs.  Using the Diagnostics Mode menu, you can 
suppress test result message printing and the abort-on-error logic.  Suppress printing with the 

p

 

toggle selection, and the abort-on-error logic with the 

e

 toggle selection.   

 
You can recall the last error at any time (before the module is powered-down or restarted) with 
the 

r

 selection.  The last detected error is retained even if the diagnostics mode is exited and re-

entered.  This is a convenient feature that you can use under these conditions:
