With online access, a distinction is made between safety-related functionality and
standard functionality. Access is controlled by double-clicking on the corresponding node
below 'Plant'. The cockpit of the safety-related CPU can be accessed via the 'Safety PLC'
node. The access is protected by the safety password you have assigned.
The monitoring mode enables read-only access to the safety-related PLC.
Since the execution of the application cannot be influenced by debug
commands, the monitoring mode is considered as a safe mode.
1. Load your project.
2. Double-click in the 'Plant' area on 'Safety PLC' node.
�� The cockpit of the safety PLC is opened.
3. Go online with your Safety CPU via
4. In the Cross-functional area in the toolbar at the bottom, click on
�� The 'Watch window' opens. In the watch window you can collect variables and
clearly show and monitor the online values while the application is running. You
can create multiple watch lists within the WATCH window. Each list can be saved
and loaded. In addition, the current online value of list elements can be loaded
from the control and used as a setpoint.
5. Drag the variables you want to monitor into the Watch window.
6. Activate the monitoring mode with
�� You now have read access to the variables in your project.
DANGER
Unintended operating state of the CPU
In contrast to the monitoring mode, the debug mode also grants write access
to the safety-related PLC. Since the execution of the application can be influ-
enced by debug commands, debug mode must be considered as non-safe
mode.
