6.16 Monitoring
For troubleshooting purposes and to study sequences of a user program you can
monitor the current state of the inputs, outputs and registers during operation.
6.16.1 Ladder diagram
With an open ladder diagram window you can start or stop the graphic observation
in the main menu under [Monitor]-[Start CPU Monitor].
The inputs and outputs are shown in different colours depending on their logical
state. The colours are freely adjustable in the dialogue [Adjust] (which can be
reached by the main menu [Options]-[Adjust]) under the [Colours] rider.
In addition to the states of the contacts, the time which has currently passed is
specified under the function ‘timer’.
Depending on requirements the interrogation/updating time of the monitoring can
be set in the dialogue [Configuration] (which can be reached by the main menu
[Options]-[Configuration]) under the instructions rider in a range of 100ms to
5000ms.
