Loop Block
A loop compound is a compound or group that contains a loop block. You configure
other blocks and compounds inside the loop compound. The compound can be added
to one of the five scan groups defined in the Interface block. All the blocks inside the
compound will be executed at that scan rate.
• The compound will also have a Compound Signals menu that can be used to
make pre-defined connections in and out of this block. (We will not use this for
now. You can close it by clicking on the close button on its right hand side top –
the X button)
8. Open the Loop block (LP-1) by double-clicking on it. The block will open as shown in
the next figure. We will not change anything in this block. Just notice that scan group this
compound belongs to defaults to Scan Group 1. (200 ms– refer to step 4 - Interface block).
