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.




NOTICE

The value of the connections is calculated from the monitored variables. This is not a genuine flow control.
