7.9.6 Online Test
The Online Test function is used to add online test fields (OLT fields) to the program logic, to
display and to force signals/variables while the controller is operating.
If the Online Test Allowed switch is on, the values of signals/variables can be manually entered
in the corresponding OLT fields and thus forced. However, the forced values only apply until
they are overwritten by the program logic.
If the Online Test Allowed switch is off, the values of the signals/variables in OLT fields are only
displayed and cannot be modified.
For more information on how to use OLT fields, enter OLT field in the online help of the
programming tool.
