VisSim allows you to group function blocks.
Highlight the block and edit it as a Compound Block.

PI and PID controller blocks are availablein the VisSim folder under the DeltaV
data. You can open these files and copyand paste the controller blocks whenrequired.
You might find it useful to check out theway these blocks are written.

Now we need to add the feedbackloop and a set point. The set pointcan be a constant.
The arrow block can be used towire in an organized manor.
To drill down to the controller just
click it!

You can save this file if you wish.
Try creating some simulations on your
own. Become familiar with the program,we will be using it from time to time.
