First programming exercise

4.8 Status view (online)

4.8

Status view (online)

Select the menu item Debug > Start

Program Status to activate the status view

of the ladder diagram.

You can now view the status of the

operands in the PLC.

In the example, switch S0 is connected to

input I0.0.

If you now actuate the switch and observe

the program in ladder status view, the

operations which are passing current

(true) are filled in blue.

The status of the operations is read

cyclically from the PLC and updated on

the screen.

In this context, online means looking

inside the controller with a PC/

programming device to view the current

states and their cyclic changes.

Very fast events cannot be tracked in this way because the time required to transfer the

data to the screen is too long. A status view is also possible for a function block diagram

(FBD).
