Check, Download, Start, and Test a Routine 4-5
Test a Routine Test a routine to check for and eliminate errors. You must have
Administrator or Read/Write access to test a routine. Test options are
discussed in the table below.
From the Test Mode menu on the Control Panel, choose the test
option you want
.
Test Option Description
Enter Test Mode (Hot Start) To enter test mode hot, a routine must be loaded and started in the controller.
After a security query, the routine is paused (FREEZE) while retaining the current process
data after terminating the cycle. No input signals are processed. The output signals retain
their current state.
Enter Test Mode (Warm Start) Halts the execution of the routine with the signals declared as Retain retaining their
values and with all other signals being reset.
Enter Test Mode (Cold Start) A routine must be loaded in the controller to allow you to enter test mode cold.
After a security query, the routine is initialized, started, and immediately enters FREEZE
mode. No input signals are processed, and all the output signals stay in their basic state.
If the routine was in RUN mode when enter test mode cold was selected, the cycle in
progress is terminated and the process data is re-initialized.
Single cycle Single cycle can only be executed when the controller is in the test mode. Use single cycle
to manually trigger the execution of a single cycle of the routine. The routine is executed
exactly once. The input signals are read in, processed, and the resulting output signals are
transferred.
Use the force editor to perform a step-by-step check of the data. See Chapter 5 for
information on forcing.
Continue with Run This option terminates the test mode. The routine mode changes from FREEZE to RUN
without re-initialization. The current process data are retained. (This corresponds to a
routine hot start.)
