A really simple question for those who know ladder logic.
I'm using a Keyence KV PLC. I have 3 devices the plc will control the loading of. The problem is they can only be loaded one at a time, and the load request from these 3 devices can come in any order, or all at once.
I need to alternate the loading of these 3 devices so one does not load more often than the others.
I have played with latches, trying to toggle the load sequence, but seam to be confusing myself.
Any suggestions of a simple way of doing this, or where I can see a piece of ladder that performs something similar?
ANY help would be appreciated.
