Programming a Multiple Instance
You can create multiple instances for any function block, even for valve control programs,
for example. If you want to work with multiple instances, note that both the calling and the
called function blocks must have multiple instance capability.
You can find more information under Help > Contents in the topics
"Programming Blocks" and "Creating Blocks and Libraries."
