Using test functions for control and monitoring of variables
For troubleshooting purposes and to display the status of certain variables
you can access certain test functions via the menu item Debug of the
Siemens SIMATIC manager.
The status of the operands and the VKE can be displayed by means of the
test function Debug > Monitor.
You can modify and/or display the status of variables by means of the test
function PLC > Monitor/Modify Variables.
This test function displays the current status and the VKE of the different
operands while the program is being executed.
It is also possible to enter corrections to the program.
Note!
When using the test function “Monitor” the PLC must be in RUN mode!
The processing of the states may be interrupted by means of jump
commands or by timer and process-related alarms. At the breakpoint the
CPU stops collecting data for the status display and instead of the required
data it only provides the PG with data containing the value 0.
For this reason, jumps or time and process alarms can result in the value
displayed during program execution remaining at 0 for the items below:
the result of the logical operation VKE
Status / AKKU 1
AKKU 2
Condition byte
absolute memory address SAZ. In this case SAZ is followed by a "?".
The interruption of the processing of statuses does not change the
execution of the program. It only shows that the data displayed is no longer.
