Display in networks
Connecting lines are displayed in color according to their actual Boolean values (blue means TRUE, black means FALSE).
Display in LD
In the online view of a ladder diagram (LD), the connecting lines are displayed in color: connections with the value TRUE are indicated by a thick blue line, connections with the value FALSE by a thick black line. In contrast, connections with an unknown or analog value are displayed normally (thin black line).
The contact and coil elements are also indicated.
For contacts and coils, a prepared value (TRUE or FALSE) is displayed in a small view next to the element.
Important
The value of the connections is calculated from the monitored variables. This is not a genuine flow control.
Display in IL
Current values are displayed in a separate column.
