I am on a new project involving using a PLC to monitor other PLCs in a warehouse. I figure I can use an AutomationDirect PLC I have for spare parts using only input modules since all of the PLCs we have use 24VDC inputs and read directly off the inputs of the other PLCs. However, I am concerned that I may possibly hinder the operation of the machines since some of the inputs would have to drive 2 input modules in serial. Should I be concerned? If not, great! If so, why and besides trying to network all of these different brands of PLCs together in their own network, what could I do along my same lines?
