With longer texts, it is possible to display the whole text by pressing the SELECT key.
When a program block is protected by a password, this softkey can be used to enable the
display of the ladder diagram.
A password is required for this. The password can be allocated during creation of a program
block in Programming Tool PLC802.
The selected program block is opened.
The name (absolute) of the program block will then be displayed on "Window 1..." softkey
(for "..." e.g. "Window 1 OB1").
Selecting this softkey activates or deactivates the program status display.
You can monitor the current status of the networks from the PLC cycle end.
The states of all operands are displayed in the "Program status" ladder diagram (top right in
the window). This LAD acquires the values for the status display in several PLC cycles and
then refreshes the status display.
