Good morning,
I am having trouble understanding the concept of consumed and produced tags. I found a manual explaining how they work but still cannot grasp the purpose.
From what I have read, one can create a produced tag on one PLC and send the tag value to multiple other PLCs as consumed tags? Why not just create 1 base tag in the first PLC and then use an Ethernet connection and daisy chain to other PLCs and get all the same tags across all controllers? Or is this not how it works?
Any explanation would be appreciated, thanks! I've never used Multiple PLCs on one project before, I usually just have one per machine and never connected all of them together.
