Stopping the Program
If the user program is stopped, the mode switches from RUN to STOP/VALID
CONFIGURATION.
7.9.5
Program Test Mode
The test mode is started from the Control Panel, selecting Test Mode -> Test Mode with Hot
Start (...Cold Start, ...Warm Start). Each Single Cycle command is used to activate a single
cycle (one complete logic cycle).
Behavior of variable/signal values in test mode
The selection of cold, warm or hot start determines which variable values are used during the
first cycle in test mode.
Cold start: all variables/signals are set to their initial values.
Warm start: retain signals retain their value, the remaining signals are set to their initial value.
Hot start: All variables/signals retain their current values.
Finally, the Cycle Step command can be used to start the user program in single step mode. All
current values are retained for the following cycle (freezed state).
WARNING
Property damage or physical injury possible due to actuators in unsafe state!
Do not use the test mode function during safety-related operation!
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.
