LOOP COMPOUNDS
Loop compound is a special compound that contains a loop block. Loop compounds are
placed at the top level of a function block diagram (where the IF, DIF, SE and ST blocks
are located). All the function blocks other than Input, Output, Modules, Communication
and System blocks have to be configured inside a loop compound.
The loop block that is present inside the loop compound specifies the scan group at which
the blocks inside the loop compound get executed. See the next figure:
Figure 1 .12.
Cancel Connection
The scan groups are configured in the Interface Block at the top level. There could be as
many as 5 different scan groups. The scan time is in multiples of 50 ms and can be as low
as 50 ms.
The next figure shows the Interface (IF) block configuration:
